"Profiler for buildbot master and its UI"

Project description

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

Usage

installation:

pip install buildbot_profiler

then in master.cfg:

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