Monitoring Jenkins using Metrics Plugin and Zabbix

This solution is composed by three parts

1. Jenkins' Metrics Plugin
2. A python (2) script, which gets metrics from above plugin and transform it in a readable Zabbix item.
3. A Zabbix Agentd config file which runs the above script and sends result to Zabbix server

Install

Install the Metrics Jenkins plugin, create a API Key (Jenkins->Configure->Metrics) Install this ansible role, configure the variables "zabbix_jenkins_url" and "zabbix_jenkins_key".

Appendix

How this python script works

It simply uses Jenkins' Metrics Plugin’s API to get a Json containing metrics and transforms it in a more readable file to Zabbix.

However you can also make use of it without a Zabbix, like shown bellow:

python jenkins-metrics.py

This will return all the metrics at once. If you want to get just one of the metrics, use a full path to a metric item. For example, to get this metric

{
  "gauges" : {
    "jenkins.executor.count.value" : {
      "value" : 52
    },
...

You can type:

python jenkins-metrics.py gauges.jenkins.executor.count.value.value
