Plugin does't expose metrics of jobs on /prometheus endpoint

[looks6]

I have issue with the plugin, I don't see metrics for a jobs for example default_jenkins_builds_duration_milliseconds_summary and so on.
I have tried everything enabled\disable authentication, and I thing that I used every possible combination of plugin configuration, but still witout desired result.
Could someone help with this issue or even direct to correct way to solve this issue?
I have poduction environment with a jenkins ver. 2.497, and prometheus metrics plugin ver. 801.
The same version have on staging env and there this works without problem
Thanks in advance

Did you use a browser for checking? If not, in some scraping Tools you need to configure a trailing / at the end. If that does not help, please check the Jenkins Controller Logs for errors and provide your Plugin configuration so we can check

I see metrics but not that which are related with job execution, so endpoint works correct.
But something impact to expose metrics from Job Collector.
I mean this metrics:
default_jenkins_builds_duration_milliseconds_summary
default_jenkins_builds_success_build_count
default_jenkins_builds_failed_build_count
default_jenkins_builds_unstable_build_count
default_jenkins_builds_total_build_count
default_jenkins_builds_aborted_build_count
default_jenkins_builds_health_score Health
default_jenkins_builds_available_builds_count
default_jenkins_builds_discard_active
default_jenkins_builds_running_build_duration_milliseconds

I have checked logs of Jenkins controller but there no related with this plugin.
Plugin config:
Path: prometheus
Default namespace: default
Enable authentication for prometheus end-point: checked
Count duration of successful builds: checked
Count duration of unstable builds: checked
Count duration of failed builds: checked
Count duration of not-built builds: checked
Count duration of aborted builds: checked
Fetch the test results of builds: checked
Job attribute name: jenkins_job
Collect disk usage: checked
Collect node status: checked

I don't know where to start troubleshooting. No logs.

Have you compared the other plugins of your dev/staging instance to the production instance? When you say that the dev/staging is working with that prometheus version it must be a difference on the Jenkins setup between staging and prod. I guess both use Java 17 for the jenkins controller? You could enable debug logging for org.jenkinsci.plugins.prometheus.JobCollector to see if that is collecting anything
