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 section.

Setup

Metrics are collected by JMX.

  1. Enable and configure JMX access to Apache ActiveMQ. See documentation for instructions.
  2. Set values in host macros {$ACTIVEMQ.USERNAME}, {$ACTIVEMQ.PASSWORD} and {$ACTIVEMQ.PORT}.

Macros used

Name Description Default
{$ACTIVEMQ.USER}

User for JMX

 admin
{$ACTIVEMQ.PASSWORD}

Password for JMX

 activemq
{$ACTIVEMQ.PORT}

Port for JMX
