Summary: Expose pause monitor metrics
Key: IMPALA-7416
URL: https://issues.apache.org/jira/browse/IMPALA-7416
Project: IMPALA
Issue Type: Improvement
Components: Backed, Frontend
Affects Versions: Impala 3.1.0
Reporter: bharath v
Impala has two instances of pause monitor threads that try to detect system
(IMPALA-3114) and GC pauses (IMPALA-6857). They detect the pauses and log
something to the daemon logs. The idea here is to summarize and expose this
information in the form of metrics in the web UI page. Something like,
* Last n pause times and timestamps (system/GC)
* Max/min pause times (system/GC)
* Total count of pauses (system/GC)
* Distribution of pause times (50%le, 75%le...99%le)
* Anything else?...
