Jenkins

Jenkins

Jenkins is a free and open source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery. It is a server-based system that runs in servlet containers such as Apache Tomcat.

Jenkins by HTTP

Overview

The template to monitor Apache Jenkins by Zabbix that work without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Requirements

Zabbix version: 6.4 and higher.

Tested versions

This template has been tested on:

  • Jenkins 2.263.1

Configuration

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

Setup

Metrics are collected by requests to Metrics API. For common metrics: Install and configure Metrics plugin parameters according official documentations. Do not forget to configure access to the Metrics Servlet by issuing API key and change macro {$JENKINS.API.KEY}.

For monitoring computers and builds: Create API token for monitoring user according official documentations and change macro {$JENKINS.USER}, {$JENKINS.API.TOKEN}. Don't forget to change macros {$JENKINS.URL}.

Macros used
