# Apache ActiveMQ by JMX

## Overview

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

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- Apache ActiveMQ 5.15.5

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.

## Setup

Metrics are collected by JMX.

1. Enable and configure JMX access to Apache ActiveMQ.
 See documentation for [instructions](https://activemq.apache.org/jmx.html).
2. Set values in host macros {$ACTIVEMQ.USERNAME}, {$ACTIVEMQ.PASSWORD} and {$ACTIVEMQ.PORT}.
