# 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: 7.0 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](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
## Setup
Metrics are collected by requests to [Metrics API](https://plugins.jenkins.io/metrics/).
For common metrics:
Install and configure Metrics plugin parameters according [official documentations](https://plugins.jenkins.io/metrics/). Do not forget to configure access to the Metrics Servlet by issuing API key and change macro {$JENKINS.API.KEY}.
For monitoring computers and builds:
Create API token for monitoring user according [official documentations](https://www.jenkins.io/doc/book/system-administration/authenticating-scripted-clients/) and change macro {$JENKINS.USER}, {$JENKINS.API.TOKEN}.
Don't forget to change macros {$JENKINS.URL}.
