Mona Chitnis commented on OOZIE-1817:
-------------------------------------
I agree we can get rid of the meters. they are not useful at the moment since
our logging levels are not quite perfect, and also errors/warns here can be due
to myriad reasons - user definitions etc, and do not necessarily pinpoint to
system issues.
the JSON attachment show useful metrics around locks and times they were held.
That will be useful.
taking a second look at code now

> Oozie timers are not biased, that is, the statistical metrics they expose are
> over the run-time of the Oozie server instead of a window of time. This makes
> them not very useful especially after the server has been running for a while
> (codehale has very efficient and easy to use biased histograms that can be
> used instead).
