Prometheus & Prometheus Jenkins plugin

[HK]

Hello,

I installed the Prometheus plugin in Jenkins 2.x.

I would like to know to configure Prometheus (yaml file) to get metrics from Prometheus Jenkins plugin.

In the simplest case, your prometheus.yml can look like:

---------

scrape_configs:

  - job_name: 'jenkins'

    scrape_interval: 15s

    static_configs:

      - targets: ['jenkins-host:12345']

---------

(where you'll want to change the target host / port to point to your Jenkins endpoint)

That's a static configuration of a target, but Prometheus also supports many different kinds of service discovery to dynamically discover targets.

If you need to change the endpoint to scrape from (/metrics by default, but could default to /prometheus in the Jenkins Prometheus plugin?), you can also set that:

---------

scrape_configs:

  - job_name: 'jenkins'

    metrics_path: '/prometheus'

    scrape_interval: 15s

    static_configs:

      - targets: ['jenkins-host:12345']

---------

It works fine with metrics_path: '/prometheus'

I am trying to scrape jenkins metrics. I have used it in same way mentioned above.
When I am trying to get metrices directly using jenkins url/prometheus. Its giving me the metrices list. 
But when I am configuring it n the prometheus config, I cant get any metrics in prometheus or in grafana.

Please suggest me the solution, I am trying to do this from so long.

Thanks in advance.

Is your Jenkins target up in the Targets page of the Prometheus UI?

You could also share your Prometheus configuration file and logs.

No, my jenkins target showing down on targets page on prometheus UI.

This is my prometheus config configurations:

- job_name: 'jenkins'

      metrics_path: '/prometheus'

      scrape_interval: 15s

      static_configs:

      - targets:

        - "jenkins_host:port"

When i try to configure Jenkins URL in Prometheus.yml file.it doesn't show any Jenkins Metrics in Prometheus UI dropdown.my prometheus.yml look like

# my global config

global:

  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.

  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration

alerting:

  alertmanagers:

  - static_configs:

    - targets:

      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.

rule_files:

  # - "first_rules.yml"

  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:

# Here it's Prometheus itself.

scrape_configs:

  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.

  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'

    # scheme defaults to 'http'.

    static_configs:

    - targets: ['localhost:1234']

    - targets: ['jenkins_host:4567']

And what is the error message? It should give you a clue about the problem.

Thanks Simon for replying the immediately and addressing pro-actively.

My issue has fixed. It was something network issue. I was using previously the loadbalancer url. Now I have given it to route53 url. And it worked.
I don't have to do any modifications.

Thanks.
