I have installed Prometheus-metrics plugin on my Jenkins, version 2.0.11.
Some of the metrics (metrics starting with 'default_jenkins' concerning build stats, but not all of them) are not returned on all scrapes, and it looks like they are showing up only while the jobs are running in Jenkins.
This is how some of the metrics look on the graph on Prometheus:
Is this the expected behavior?
How can I expose all of the metrics all of the times?

Background: I have a linux server where I configured my jenkins and installed the prometheus plugin to scrape the jenkins instance metrics. I am using grafana dashboard to visualize and monitor the jenkins server. In grafana I have used the grafana's pre-configured jenkins dashboard for jenkins monitoring and prometheus datasource to import the metrics to Grafana.
> Jenkins url - https://<ipaddr>:8080/test
> Prometheus scrape jenkins metrics url: https://<ipaddr>:8080/test/prometheus
Problem statement: Whenever I stop the jenkins process on my jenkins server then the grafana dashboard show as "no data available" or whenever there is some issue with prometheus plugin then also it shows "no data available". I know this is happening because prometheus is unable to scrape the metrics since the jenkins server itself is down which results in blank data passed to grafana from prometheus datasource. I just wanted to know is there any way where I could display the specific metrics in grafana which says jenkins down when jenkins process is stopped. Grafana should say the exact error at jenkins instead of just saying "no data available". Is there any custom grafana way to display the error message atleast when there is a problem with jenkins server itself.
We have multiple Jenkin masters and have enabled Jenkins Prometheus plugin and connected these masters as data sources to Grafana. I am currently interested in finding jobs which are waiting for executors for more than a certain time and create an alert based on this. I looked at Jenkins metrics but did not find any suitable metric to have monitoring for this use case. How can I achieve this?
You can access the Jenkins build queue via Groovy and check for entries waiting for too long.
It is possible to run Groovy scripts via the Jenkins REST API, which then will be your interface for polling for such "blocked" jobs.
I am facing some issues in fetching Jenkins build data into influxDB. Actually, the main requirement is to show Jenkins job build results on Grafana dashboard. So, I have created a Jenkins freestyle job and also installed influxDB plugin(1.17) and then I executed Windows batch command (as I am using a Windows 7 machine). it throws nullpointerexception. Please let me know what i need to do.
Images are given below.

I currently am using filebeat to ship my Jenkins build log from /var/log/jenkins.
I grok the build logs with Logstash so I can display the success/fail etc in Kibana and make some dashboard --> this is working well.
One thing I cannot seem to get is the total build times for the job as a whole.
I am using pipeline and multi pipeline build job types.
I can see the build stage time totals in the console logs but no matter the logging level I set globally for Jenkins, these do not display in the logs.
Has anyone managed to get this right?
Thanks
We have been using this Jenkins logstash-plugin https://wiki.jenkins.io/display/JENKINS/Logstash+Plugin
successfully to stash the data from Jenkins jobs to elasticsearch.
Supported indexers by this plugins are available in this link
https://wiki.jenkins.io/display/JENKINS/Logstash+Plugin#LogstashPlugin-IndexersCurrentlySupported
We are using the elasticsearch indexer which stashes the data directly to elasticsearch but if you want your data to go via logstash you can use Logstash indexer.
The payload format for the data is as below

I have a jenkins instance running around 200 jobs. What I need is a plugin to show the build statistics for all the jobs.
Total Builds for each project
Failures
Success
Average time per build.
Searched a lot, but couldn't find a proper report plugin. Please help
These are few which you can look depending on how much customization/features you want to do/display:
https://wiki.jenkins-ci.org/display/JENKINS/Global+Build+Stats+Plugin
https://wiki.jenkins-ci.org/display/JENKINS/build-metrics-plugin
https://wiki.jenkins-ci.org/display/JENKINS/Project+Statistics+Plugin
https://wiki.jenkins-ci.org/display/JENKINS/eXtreme+Feedback+Panel+Plugin
https://wiki.jenkins-ci.org/display/JENKINS/InfluxDB+Plugin
https://wiki.jenkins-ci.org/display/JENKINS/CouchDB+Statistics+Plugin
And there is Dashboard-View too.
For collecting nodes machine metrics (CPU Time/ Used Memory / Build Time per node etc.), I found the monitoring plugin to be the best.
https://wiki.jenkins.io/display/JENKINS/Monitoring
When it comes to aggregates build times group by job, I couldn't find anything good within Jenkins UI, but if you have a datadog license, you can just enable the datadog Jenkins plugin, configure the datadog api key and hostname in Jenkins Config, and you are good to go.
