IMPALA-11553: Add event specific metrics in the
table metrics
This patch adds an event specific metric "avg-events-process-duration"
at the table level metrics. This metric is also extended to last 1min,
5mins, 15mins duration. This mertic is useful to identify the average
events processed duration on the table. This is helpful to identify if
a particular table is causing event procssor lagging and as a temporary
workaround, event processing can be disabled on that table.
Another metric is also added in the event processor summary page,
"events-consuming-delay-ms", is the time difference in milliseconds of
the event created in the metastore and event processed by event
processor. This is another useful metric to gauge how the event
processor is lagging.
Tests:
- Manually verified the metrics on catalogD UI page when running some
hive workloads.
