# Ignite by JMX

## Overview

For Zabbix version: 5.0 and higher  
Official JMX Template for Apache Ignite computing platform.
This template is based on the original template developed by Igor Akkuratov, Senior Engineer at GridGain Systems and Apache Ignite Contributor.


This template was tested on:

- Zabbix, version 5.0
- Ignite, version 2.9.0

## Setup

> See [Zabbix template operation](https://www.zabbix.com/documentation/5.0/manual/config/templates_out_of_the_box/jmx) for basic instructions.

This template works with standalone and cluster instances. Metrics are collected by JMX. All metrics are discoverable.

1. Enable and configure JMX access to Apache Ignite. See documentation for [instructions](https://docs.oracle.com/javase/8/docs/technotes/guides/management/agent.html). Current JMX tree hierarchy contains classloader by default. Add the following jvm option `-DIGNITE_MBEAN_APPEND_CLASS_LOADER_ID=false`to will exclude one level with Classloader name. You can configure Cache and Data Region metrics which you want using [official guide](https://ignite.apache.org/docs/latest/monitoring-metrics/configuring-metrics).
2. Set the user name and password in host macros {$IGNITE.USER} and {$IGNITE.PASSWORD}.

## Zabbix configuration

No specific Zabbix configuration is required.
