Apache Tomcat by JMX

Overview

For Zabbix version: 6.2 and higher
Official JMX Template for Apache Tomcat.

This template was tested on:

Apache Tomcat, version 8.5.59

Setup

See Zabbix template operation for basic instructions.

Metrics are collected by JMX.

Enable and configure JMX access to Apache Tomcat. See documentation for instructions (chose your version).
If your Tomcat installation require authentication for JMX, set values in host macros {$TOMCAT.USERNAME} and {$TOMCAT.PASSWORD}.
You can set custom macro values and add macros with context for specific metrics following macro description.

Zabbix configuration

No specific Zabbix configuration is required.
