# HPE Primera by HTTP

## Overview

The template to monitor HPE Primera by HTTP.
It works without any external scripts and uses the script item.

## Requirements

Zabbix version: 7.2 and higher.

## Tested versions

This template has been tested on:
- HPE Primera 4.2.1.6

## 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

1. Create a user on the storage with a browse role and enable it for all domains, for example "zabbix".
2. The WSAPI server does not start automatically.
   Log in to the CLI as Super, Service, or any role granted the wsapi_set right.
   Start the WSAPI server by command: `startwsapi`.
   To check WSAPI state use command: `showwsapi`.
3. Link template to the host.
4. Set the hostname or IP address of the host in the {$HPE.PRIMERA.API.HOST} macro and configure the username and password in the {$HPE.PRIMERA.API.USERNAME} and {$HPE.PRIMERA.API.PASSWORD} macros.
5. Change the {$HPE.PRIMERA.API.SCHEME} and {$HPE.PRIMERA.API.PORT} macros if needed.
