# AWS by HTTP

## Overview

This template is designed for the effortless deployment of AWS monitoring by Zabbix via HTTP and doesn't require any external scripts.

## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

Before using the template, you need to create an IAM policy for the Zabbix role in your AWS account with the necessary permissions.

Add the following required permissions to your Zabbix IAM policy in order to collect metrics.
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "ec2:DescribeInstances",
                "ec2:DescribeVolumes",
                "ec2:DescribeRegions",
                "rds:DescribeEvents",
                "rds:DescribeDBInstances",
                "ecs:DescribeClusters",
                "ecs:ListServices",
                "ecs:ListTasks",
                "ecs:ListClusters",
                "s3:ListAllMyBuckets",
                "s3:GetBucketLocation",
                "s3:GetMetricsConfiguration",
                "elasticloadbalancing:DescribeLoadBalancers",
                "elasticloadbalancing:DescribeTargetGroups",
                "ec2:DescribeSecurityGroups",
                "lambda:ListFunctions"
            ],
            "Effect": "Allow",
            "Resource": "*"
        }
    ]
}
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "ec2:DescribeInstances",
                "ec2:DescribeVolumes",
                "ec2:DescribeRegions",
                "rds:DescribeEvents",
                "rds:DescribeDBInstances",
                "ecs:DescribeClusters",
                "ecs:ListServices",
                "ecs:ListTasks",
                "ecs:ListClusters",
                "s3:ListAllMyBuckets",
                "s3:GetBucketLocation",
                "s3:GetMetricsConfiguration",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation",
                "elasticloadbalancing:DescribeLoadBalancers",
                "elasticloadbalancing:DescribeTargetGroups",
                "ec2:DescribeSecurityGroups",
                "lambda:ListFunctions"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, add the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "ec2:DescribeInstances",
                "ec2:DescribeVolumes",
                "ec2:DescribeRegions",
                "rds:DescribeEvents",
                "rds:DescribeDBInstances",
                "ecs:DescribeClusters",
                "ecs:ListServices",
                "ecs:ListTasks",
                "ecs:ListClusters",
                "s3:ListAllMyBuckets",
                "s3:GetBucketLocation",
                "s3:GetMetricsConfiguration",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation",
                "elasticloadbalancing:DescribeLoadBalancers",
                "elasticloadbalancing:DescribeTargetGroups",
                "ec2:DescribeSecurityGroups",
                "lambda:ListFunctions"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

To gather Request metrics, enable [Requests metrics](https://docs.aws.amazon.com/AmazonS3/latest/userguide/cloudwatch-monitoring.html) on your Amazon S3 buckets from the AWS console.

Set the macros: `{$AWS.AUTH_TYPE}`. Possible values: `access_key`, `assume_role`, `role_base`.

If you are using access key-based authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about managing access keys, see [official documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).

# AWS EC2 by HTTP

## Overview

The template to monitor AWS EC2 and attached AWS EBS volumes by HTTP via Zabbix that works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
*NOTE*
This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS EC2 by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template get AWS EC2 and attached AWS EBS volumes metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy with the necessary permissions for the Zabbix role in your AWS account.

Add the following required permissions to your Zabbix IAM policy in order to collect Amazon EC2 metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
              "ec2:DescribeVolumes",
              "cloudwatch:"DescribeAlarms",
              "cloudwatch:GetMetricData"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
  ```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "ec2:DescribeVolumes",
                "cloudwatch:"DescribeAlarms",
                "cloudwatch:GetMetricData"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "ec2:DescribeVolumes",
                "cloudwatch:"DescribeAlarms",
                "cloudwatch:GetMetricData"
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

For more information, see the [EC2 policies](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/security-iam.html) on the AWS website.

Set the macros: `{$AWS.AUTH_TYPE}`, `{$AWS.REGION}`, `{$AWS.EC2.INSTANCE.ID}`.

If you are using access key-based authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about manage access keys, see [official documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys)

|Credit CPU: Balance|<p>The number of earned CPU credits that an instance has accrued since it was launched or started. For T2 Standard, the CPUCreditBalance also includes the number of launch credits that have been accrued.</p><p>Credits are accrued in the credit balance after they are earned, and removed from the credit balance when they are spent. The credit balance has a maximum limit, determined by the instance size. After the limit is reached, any new credits that are earned are discarded. For T2 Standard, launch credits do not count towards the limit.</p><p>The credits in the CPUCreditBalance are available for the instance to spend to burst beyond its baseline CPU utilization.</p><p>When an instance is running, credits in the CPUCreditBalance do not expire. When a T3 or T3a instance stops, the CPUCreditBalance value persists for seven days. Thereafter, all accrued credits are lost. When a T2 instance stops, the CPUCreditBalance value does not persist, and all accrued credits are lost.</p>|Dependent item|aws.ec2.cpu.credit_balance<p>**Preprocessing**</p><ul><li><p>JSON Path: `$.[?(@.Label == "CPUCreditBalance")].Values.first().first()`</p><p>⛔️Custom on fail: Discard value</p></li></ul>|

# AWS RDS instance by HTTP

## Overview

The template to monitor AWS RDS instance by HTTP via Zabbix that works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
*NOTE*
This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

Additional information about metrics and used API methods:

* [Full metrics list related to RDS](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-metrics.html)
* [Full metrics list related to Amazon Aurora](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.AuroraMySQL.Monitoring.Metrics.html#Aurora.AuroraMySQL.Monitoring.Metrics.instances)
* [DescribeAlarms API method](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html)


## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS RDS instance by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template get AWS RDS instance metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy with the necessary permissions for the Zabbix role in your AWS account.

Add the following required permissions to your Zabbix IAM policy in order to collect Amazon RDS metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "rds:DescribeEvents",
                "rds:DescribeDBInstances"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "rds:DescribeEvents",
                "rds:DescribeDBInstances"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "rds:DescribeEvents",
                "rds:DescribeDBInstances",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the macros: `{$AWS.AUTH_TYPE}`, `{$AWS.REGION}`, `{$AWS.RDS.INSTANCE.ID}`.

If you are using access key-based authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about manage access keys, see [official documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys)

Also, see the Macros section for a list of macros used for LLD filters.

# AWS S3 bucket by HTTP

## Overview

The template to monitor AWS S3 bucket by HTTP via Zabbix that works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
*NOTE*
This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

Additional information about metrics and used API methods:

* [Full metrics list related to S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/metrics-dimensions.html)
* [DescribeAlarms API method](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html)

## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS S3 bucket by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template gets AWS S3 metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy for the Zabbix role in your AWS account with the necessary permissions.

Add the following required permissions to your Zabbix IAM policy in order to collect Amazon S3 metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
              "cloudwatch:DescribeAlarms",
              "cloudwatch:GetMetricData",
              "s3:GetMetricsConfiguration"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "s3:GetMetricsConfiguration"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "s3:GetMetricsConfiguration",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

To gather Request metrics, [enable Requests metrics](https://docs.aws.amazon.com/AmazonS3/latest/userguide/cloudwatch-monitoring.html) on your Amazon S3 buckets from the AWS console.

You can also define a filter for the Request metrics using a shared prefix, object tag, or access point.

Set the macros: `{$AWS.AUTH_TYPE}`, `{$AWS.S3.BUCKET.NAME}`.

If you are using access key-based authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about manage access keys, see [official documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys)

Also, see the Macros section for a list of macros used for LLD filters.

# AWS ECS Serverless Cluster by HTTP

## Overview

The template to monitor AWS ECS Serverless Cluster by HTTP via Zabbix that works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
*NOTE*
This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

Additional information about the metrics and used API methods:

* [Full metrics list related to ECS](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Container-Insights-metrics-ECS.html)
* [DescribeAlarms API method](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html)

## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS ECS Cluster by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template gets AWS ECS metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy for the Zabbix role in your AWS account with the necessary permissions.

Add the following required permissions to your Zabbix IAM policy in order to collect Amazon ECS metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
              "cloudwatch:DescribeAlarms",
              "cloudwatch:GetMetricData",
              "ecs:ListServices"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "ecs:ListServices"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "ecs:ListServices",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [

            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the following macros `{$AWS.AUTH_TYPE}`, `{$AWS.REGION}`, `{$AWS.ECS.CLUSTER.NAME}`.

If you are using access key-based authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about managing access keys, see [official documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys)

Refer to the Macros section for a list of macros used for LLD filters.

# AWS ECS Cluster by HTTP

## Overview

The template to monitor AWS ECS Cluster by HTTP via Zabbix that works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
*NOTE*
This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

Additional information about the metrics and used API methods:

* [Full metrics list related to ECS](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Container-Insights-metrics-ECS.html)
* [DescribeAlarms API method](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html)

## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS ECS Cluster by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template gets AWS ECS metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy for the Zabbix role in your AWS account with the necessary permissions.

Add the following required permissions to your Zabbix IAM policy in order to collect Amazon ECS metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
              "cloudwatch:DescribeAlarms",
              "cloudwatch:GetMetricData",
              "ecs:ListServices"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "ecs:ListServices"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "ecs:ListServices",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the following macros `{$AWS.AUTH_TYPE}`, `{$AWS.REGION}`, `{$AWS.ECS.CLUSTER.NAME}`.

If you are using access key-based authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about managing access keys, see [official documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys)

# AWS ELB Application Load Balancer by HTTP

## Overview

*Please scroll down for AWS ELB Network Load Balancer by HTTP.*

The template is designed to monitor AWS ELB Application Load Balancer by HTTP via Zabbix, and it works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

Additional information about metrics and API methods used in the template:
* [Full metrics list related to AWS ELB Application Load Balancer](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-cloudwatch-metrics.html)
* [DescribeAlarms API method](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html)
* [DescribeTargetGroups API method](https://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/API_DescribeTargetGroups.html)


## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS ELB Application Load Balancer with Target Groups by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template gets AWS ELB Application Load Balancer metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy with the necessary permissions for the Zabbix role in your AWS account. For more information, visit the [ELB policies page](https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/elb-api-permissions.html) on the AWS website.

Add the following required permissions to your Zabbix IAM policy in order to collect AWS ELB Application Load Balancer metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
              "cloudwatch:DescribeAlarms",
              "cloudwatch:GetMetricData",
              "elasticloadbalancing:DescribeTargetGroups"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "elasticloadbalancing:DescribeTargetGroups"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "elasticloadbalancing:DescribeTargetGroups",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the macros: `{$AWS.AUTH_TYPE}`, `{$AWS.REGION}`, and `{$AWS.ELB.ARN}`.

If you are using access key-based authorization, set the macros `{$AWS.ACCESS.KEY.ID}` and `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about managing access keys, see [official AWS documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).

# AWS ELB Network Load Balancer by HTTP

## Overview

The template is designed to monitor AWS ELB Network Load Balancer by HTTP via Zabbix, and it works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

Additional information about metrics and API methods used in the template:
* [Full metrics list related to AWS ELB Network Load Balancer](https://docs.aws.amazon.com/elasticloadbalancing/latest/network/load-balancer-cloudwatch-metrics.html)
* [DescribeAlarms API method](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html)
* [DescribeTargetGroups API method](https://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/API_DescribeTargetGroups.html)


## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS ELB Network Load Balancer with Target Groups by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template gets AWS ELB Network Load Balancer metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy with the necessary permissions for the Zabbix role in your AWS account. For more information, visit the [ELB policies page](https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/elb-api-permissions.html) on the AWS website.

Add the following required permissions to your Zabbix IAM policy in order to collect AWS ELB Network Load Balancer metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
              "cloudwatch:DescribeAlarms",
              "cloudwatch:GetMetricData",
              "elasticloadbalancing:DescribeTargetGroups"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "elasticloadbalancing:DescribeTargetGroups"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [

Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the macros: `{$AWS.AUTH_TYPE}`, `{$AWS.REGION}`, and `{$AWS.ELB.ARN}`.

If you are using access key-based authorization, set the macros `{$AWS.ACCESS.KEY.ID}` and `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about managing access keys, see [official AWS documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).

See the section below for a list of macros used for LLD filters.

# AWS Lambda by HTTP

## Overview

This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics.
For more information, please refer to the [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) page.

Additional information about metrics and API methods used in the template:
* [Full metrics list related to AWS Lambda](https://docs.aws.amazon.com/lambda/latest/dg/monitoring-metrics.html)
* [DescribeAlarms API method](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_DescribeAlarms.html)


## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS Lambda by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

The template gets AWS Lambda metrics and uses the script item to make HTTP requests to the CloudWatch API.

Before using the template, you need to create an IAM policy with the necessary permissions for the Zabbix role in your AWS account. For more information, visit the [Lambda permissions page](https://docs.aws.amazon.com/lambda/latest/dg/lambda-permissions.html) on the AWS website.

Add the following required permissions to your Zabbix IAM policy in order to collect AWS Lambda metrics.
```json
{
    "Version":"2012-10-17",
    "Statement":[
        {
          "Action":[
              "cloudwatch:DescribeAlarms",
              "cloudwatch:GetMetricData"
          ],
          "Effect":"Allow",
          "Resource":"*"
        }
    ]
  }
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {

            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",

        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, set the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",

                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the macros: `{$AWS.AUTH_TYPE}`, `{$AWS.REGION}`, and `{$AWS.LAMBDA.ARN}`.

If you are using access key-based authorization, set the macros `{$AWS.ACCESS.KEY.ID}` and `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about managing access keys, see the [official AWS documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).

# AWS Cost Explorer by HTTP

## Overview

The template to monitor AWS Cost Explorer by HTTP via Zabbix, which works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
*NOTE*
This template uses the Cost Explorer API calls to list and retrieve metrics.
For more information, please refer to the [Cost Explorer pricing](https://aws.amazon.com/aws-cost-management/aws-cost-explorer/pricing/) page.


## Requirements

Zabbix version: 7.4 and higher.

## Tested versions

This template has been tested on:
- AWS by HTTP

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.4/manual/config/templates_out_of_the_box) section.

## Setup

Before using the template, you need to create an IAM policy for the Zabbix role in your AWS account with the necessary permissions.

* [IAM policies for AWS Cost Management](https://docs.aws.amazon.com/cost-management/latest/userguide/billing-permissions-ref.html)

Add the following required permissions to your Zabbix IAM policy in order to collect metrics.
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "ce:GetDimensionValues",
                "ce:GetCostAndUsage"
            ],
            "Effect": "Allow",
            "Resource": "*"
        }
    ]
}
```
For using assume role authorization, add the appropriate permissions to the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "ce:GetDimensionValues",
                "ce:GetCostAndUsage"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
```
If you are using role-based authorization, add the appropriate permissions:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"
        },
        {
            "Effect": "Allow",
            "Action": [
                "ce:GetDimensionValues",
                "ce:GetCostAndUsage",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}
```
Next, add a principal to the trust relationships of the role you are using:
```json
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}
```
**Note**, Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the macros: `{$AWS.AUTH_TYPE}`. Possible values: `access_key`, `assume_role`, `role_base`.

If you are using access key-based authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`.

If you are using access assume role authorization, set the following macros: `{$AWS.ACCESS.KEY.ID}`, `{$AWS.SECRET.ACCESS.KEY}`, `{$AWS.STS.REGION}`, `{$AWS.ASSUME.ROLE.ARN}`.

For more information about managing access keys, see the [official documentation](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).

Also, see the Macros section for a list of macros used in LLD filters.
