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?... -- This message was sent by Atlassian JIRA (v7.6.3#76005)
