Hello Kudu Jenkins, Adar Dembo,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/15212
to look at the new patch set (#5).
Change subject: [hybrid clock] KUDU-3048 introduce new clock metrics
......................................................................
[hybrid clock] KUDU-3048 introduce new clock metrics
Introduced additional metrics for the hybrid clock:
* whether hybrid clock is using extrapolated readings for the
underlying clock instead of actual readings
* histogram for the duration of intervals when the underlying clock
was extrapolated
* histogram for the maximum errors reported by the underlying clock
I ran a small Kudu cluster to manually verify the behavior of the
newly introduced metrics: I'm not sure it's worth adding automated
tests for this given the already existing 'hybrid_clock_error' metric
didn't have any test coverage.
