# Ignite by JMX

## Overview

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.

## Requirements

Zabbix version: 6.0 and higher.

## Tested versions

This template has been tested on:
- Ignite 2.9.0

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/6.0/manual/config/templates_out_of_the_box) section.

## Setup

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}.

### Macros used
