Source: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/db/gridgain_jmx?at=release/7.4

GridGain by JMX

Overview

Official JMX Template for GridGain In-Memory Computing Platform. This template is based on the original template developed by Igor Akkuratov, Senior Engineer at GridGain Systems and GridGain In-Memory Computing Platform Contributor.

Requirements

Zabbix version: 7.4 and higher.

Tested versions

This template has been tested on:

  • GridGain 8.8.5

Configuration

Zabbix should be configured according to the instructions in the 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 GridGain In-Memory Computing Platform. See documentation for instructions. Current JMX tree hierarchy contains classloader by default. Add the following jvm option -DIGNITE_MBEAN_APPEND_CLASS_LOADER_ID=falseto will exclude one level with Classloader name. You can configure Cache and Data Region metrics which you want using official guide.
  2. Set the user name and password in host macros {$GRIDGAIN.USER} and {$GRIDGAIN.PASSWORD}.

Macros used
