[JENKINS-32689] Load statistics graph don't show the correct number of executors #7804

Open timja opened 8 years ago

timja commented 8 years ago

I just set up a new Jenkins and was checking out how the load was during our nightly builds, when I noticed that the graph is missing 2 executors. Playing with shutting down the slaves it appears to be the executors on the master that are not included in the graph.

I am showing the graph for the whole installation, not for any specific node. I must say that checking the graph for the master only actually does show 2 executors!

Please check the attached screenshots. On the screenshot with the running project, you can actually see the graph is going down – this also made me think that Jenkins is not calculating the master executors.

We have a single (master) Windows Jenkins node with 4 executors, no slaves. Running Jenkins v2.48

Viewing the load statistics for the entire system (http://jenkins/load-statistics ) only displays queue length, with zero executors (online, busy or available)

Viewing the load statistics just for the master node (http://jenkins/computer/(master)/load-statistics ) over the same period, displays the executors, but zero queue length.

Surely these two graphs should look the same, and both include all 4 metrics?

Beware of https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/slaves/NodeProvisioner.java when fixing this.
