Apache Tomcat by JMX

Overview

This template is designed for the effortless deployment of Apache Tomcat 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 Tomcat 8.5.59

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

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.

Apache Tomcat by JMX

Overview

For Zabbix version: 5.4 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.

Macros used

Name	Description	Default
{$TOMCAT.LLD.FILTER.MATCHES}	Filter for discoverable objects. Can be used with following contexts: "GlobalRequestProcessor", "ThreadPool", "Manager"	`.*`
{$TOMCAT.LLD.FILTER.NOT_MATCHES}	Filter to exclude discovered objects. Can be used with following contexts: "GlobalRequestProcessor", "ThreadPool", "Manager"	`CHANGE IF NEEDED`
{$TOMCAT.PASSWORD}	Password for JMX	``
{$TOMCAT.THREADS.MAX.PCT}	Threshold for busy worker threads trigger. Can be used with {#JMXNAME} as context.	`75`
{$TOMCAT.THREADS.MAX.TIME}	The time during which the number of busy threads can exceed the threshold. Can be used with {#JMXNAME} as context.	`5m`
