1.Set up Jenkins, prometheus, grafana

docker run -d --name jenkins -p 8081:8080 -p 50000:50000 jenkins/jenkins:latest
docker run -d --name prometheus -p 9090:9090 prom/prometheus
docker run -d --name grafana -p 3000:3000 grafana/grafana

2. Configure Jenkins prometheus

2.1 Install necessary plugin in Jenkins

Go to “manage Jenkins” then “manage plugins” and install “Prometheus metrics”.

Prometheus metrics

docker restart jenkins

prometheus plugin doesn’t support dynamic loading. Jenkins needs to be restarted for the update to take effect.

You can see the output of this plugin visiting this URL “http://Jenkins_HOST:PORT/prometheus”

2.2 Configure Prometheus to scrape metrics from Jenkins:

In the scrape_configs part you need to add a job for Jenkins server:

docker exec -it prometheus sh

tee -a /etc/prometheus/prometheus.yml <<EOF
  - job_name: jenkins
    metrics_path: /prometheus
    static_configs:
      - targets: ['172.17.0.1:8081']
EOF

172.17.0.1 docker bridges ip docker restart prometheus

check it: go to http://localhost:9090/targets

3.Add dashboard on grafana

• 1.Go to Grafana server localhost:3000 and login. The default user and password are “admin/admin”

• 2.From “ Home Dashboard” click on “add data source” then click on “Prometheus”.

• 3.add a exist dashboard

Login to Grafana, and add Dashboard with ID: 9964
