Overall jobs timeline

[Fabian Cenedese]

Hi

I want to find out when the Jenkins instance is loaded the most,
in the sense of how many jobs are running in parallel, how long
do they need etc.
There's the build history with timeline in every single job. But I'd
like to have an overview over all jobs, maybe in a gantt diagram
like the jenkins-timeline-plugin does for one job.

Does something like this exist? Would I need to poll all jobs
to get their build times and create my own diagram?

Thanks

bye Fabi
