# RabbitMQ cluster by Zabbix agent

## Overview

This template is developed to monitor the messaging broker RabbitMQ by Zabbix that works without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

The template `RabbitMQ Cluster` — collects metrics by polling [RabbitMQ management plugin](https://www.rabbitmq.com/management.html) with Zabbix agent.


## Requirements

Zabbix version: 7.2 and higher.

## Tested versions

This template has been tested on:
- RabbitMQ 3.5.7, 3.7.7, 3.7.17, 3.7.18, 3.8.5, 3.8.12 

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.2/manual/config/templates_out_of_the_box) section.

## Setup

Enable the RabbitMQ management plugin. See [RabbitMQ documentation](https://www.rabbitmq.com/management.html) for the instructions.

Create a user to monitor the service:

```bash
rabbitmqctl add_user zbx_monitor <PASSWORD>
rabbitmqctl set_permissions  -p / zbx_monitor "" "" ".*"
rabbitmqctl set_user_tags zbx_monitor monitoring
```

A login name and password are also supported in macros functions:

- {$RABBITMQ.API.USER}
- {$RABBITMQ.API.PASSWORD}

If your cluster consists of several nodes, it is recommended to assign the `cluster` template to a separate balancing host.
In the case of a single-node installation, you can assign the `cluster` template to one host with a `node` template.

If you use another API endpoint, then don't forget to change `{$RABBITMQ.API.CLUSTER_HOST}` macro.

Install and setup [Zabbix agent](https://www.zabbix.com/documentation/7.2/manual/installation/install_from_packages).

# RabbitMQ node by Zabbix agent

## Overview

This template is developed to monitor RabbitMQ by Zabbix that works without any external scripts.

Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

  The template `RabbitMQ Node` — (Zabbix version >= 4.2) collects metrics by polling [RabbitMQ management plugin](https://www.rabbitmq.com/management.html) with Zabbix agent.

  It also uses Zabbix agent to collect RabbitMQ Linux process statistics, such as CPU usage, memory usage, and whether the process is running or not.


## Requirements

Zabbix version: 7.2 and higher.

## Tested versions

This template has been tested on:
- RabbitMQ 3.5.7, 3.7.7, 3.7.17, 3.7.18, 3.8.5, 3.8.12 

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.2/manual/config/templates_out_of_the_box) section.

## Setup

Enable the RabbitMQ management plugin. See [RabbitMQ documentation](https://www.rabbitmq.com/management.html) for the instructions.

Create a user to monitor the service:

```bash
rabbitmqctl add_user zbx_monitor <PASSWORD>
rabbitmqctl set_permissions  -p / zbx_monitor "" "" ".*"
rabbitmqctl set_user_tags zbx_monitor monitoring
```

A login name and password are also supported in macros functions:

- {$RABBITMQ.API.USER}
- {$RABBITMQ.API.PASSWORD}

If you use another API endpoint, then don't forget to change `{$RABBITMQ.API.HOST}` macro.
Install and setup [Zabbix agent](https://www.zabbix.com/documentation/7.2/manual/installation/install_from_packages).
