11Zuul comes with support for the statsd protocol, when enabled and configured
Michael Prokop526926a2013-10-24 16:16:57 +0200[diff] [blame]12(see below), the Zuul scheduler will emit raw metrics to a statsd receiver
James E. Blaireff5a9d2017-06-20 00:00:37 -0700[diff] [blame]13which let you in turn generate nice graphics.

James E. Blairded241e2017-10-10 13:22:40 -0700[diff] [blame]18Statsd support uses the ``statsd`` python module. Note that support
19is optional and Zuul will start without the statsd python module
20present.

131which took 40 seconds to build, the Zuul scheduler will emit the
132following statsd events:
