Sravya Tirukkovalur updated SENTRY-477:
---------------------------------------
Attachment: SENTRY-477.WIP.patch
Attaching a WIP patch which generates timer metrics for each meta data
modifying thrift operation, that is create role, drop role, grant, revoke etc.
Console reporter or JMX reporter can be configured using Sentry property
"sentry.service.reporting" to either "console" or "jmx". Following is the
information exposed by timer metrics of codahale:

It mainly exposes rates of each operation, and a histogram of time taken to
serve the request, which can be useful for monitoring purposes. [~lskuff],
[~prasadm]: any suggestions on what other metrics would be good to capture? I
was also planning to
- Add some timers to jdo layer to get a sense of what % of time is being spent
in jdo operations in the entire thrift call.
- Also add the timer metrics for non meta data modifying thrift calls.
