jenkins_builds_duration_milliseconds_summary wont get displayed in prometheus

add following environment vars:

PROMETHEUS_NAMESPACE=testing
PROMETHEUS_ENDPOINT=metrics

when i check my metrics

http://localhost:8080/metrics/

# HELP testing_jenkins_builds_duration_milliseconds_summary Summary of Jenkins build times in milliseconds by Job
# TYPE testing_jenkins_builds_duration_milliseconds_summary summary
testing_jenkins_builds_duration_milliseconds_summary_count{job="TEST1",} 1.0
testing_jenkins_builds_duration_milliseconds_summary_sum{job="TEST1",} 1.0
testing_jenkins_builds_duration_milliseconds_summary_count{job="TEST2",} 31.0
testing_jenkins_builds_duration_milliseconds_summary_sum{job="TEST2",} 31.0

But i cant see these entries in prometheus… All the other metrics are working fine and get displayed.

I experienced the same problem. My solution was to set ACL in Jenkins to allow anonymous user to read jobs as that is the user prometheus scrape client is using.

Now that I got it working, let me share what I did and also describe the situation we have…

We are using the Multi-branch plugin and have a private organisation on Github. So our repos are private. We can use our (personal) Github account to log into Jenkins. The prometheus plugin was not able to show the build metrics for those repos. Since we have also have a ‘generic’ user that is allowed to access Github and clone repos in order to be able to build them, I used the same user to create a token which I then use to do the authentication for the plugin for.

In the prometheus.yml (where we do the scraping of the metrics) I added a basic_authentication part where the username is the username of the ‘generic’ user. The password is the token that was generated on Github.

After this, it worked for me!
