Checkout http://pycounters.readthedocs.org/ for more details.

0.7:

• Fixed: a busy leader which doesn’t respond to a ping on a timely fashion was not handled correctly.

0.6:

• NEW: new types of counters MaxWindowCounter, MinWindowCounter

• IMPORTANT: changes in package structure, counters module split int sub modules. Backward compatible as long as no internals were used.

• Fixed: removing a counter by name caused an exception

• Fixed: too short queue on multi process server caused pycounters to fail if used on >~10 processes

• Fixed: starting up a new process in a multi-process auto election setup caused JSON reporter to output an empty file (which will then be updated in the next cycle)

• Fixed - locking issue with JSON output files

• Fixed - EventCounter did not respond to events keyword argument

0.4:

• Added a role option to multi process reporting initializations.

• Made all report_* and shortcuts decorators usable as context managers.
