buildbot-profiler 1.0.0

"Profiler for buildbot master and its UI"

This plugin implements a profiler for buildbot master.

• It uses statistical profiling loosely based on plop https://github.com/bdarnell/plop

• Suitable for prod as statistical profiling is very low overhead

• Profiles all threads including main thread and db threads

• Removes noise samples when the threads are actually in the main loop

• In-browser UI based on nvd3 and d3-flame-graph

• Show cpu and memory percent over time

• flame graph can be restricted to a subset of the trace

• Detailed caller/callee are displayed when clicking on a function

c['www']['plugins']['profiler'] = True
