Keeping track of buildbot usage

Mozilla Release Engineering provides some simple trending of the Buildbot continuous integration system, which can be useful to check how many jobs are currently running versus pending. There are graphs of the last 24 hours broken out in various ways – for example compilation separate from tests, compilation on try and everything else. This data also feeds into the pending queue on trychooser.

ImageUntil recently the mapping of job name to machine pool was out of date, due to our rapid growth for b2g and into Amazon’s AWS, so the graphs were more misleading than useful. This has now been corrected and I’m working on making sure it stays up to date automatically.

Update: Since July 18 the system stays up to date automatically, in just about all cases.
