             Summary: Add catalog metrics for total pending events and lag time of the event-processor
                 Key: IMPALA-12492
                 URL: https://issues.apache.org/jira/browse/IMPALA-12492
             Project: IMPALA
          Issue Type: New Feature
          Components: Catalog
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


We have last-synced-event-time and latest-event-time on the catalogd WebUI. It's tedious for users to calculate their difference to get the lag time. It'd be useful if the WebUI shows the lag directly, especially in a human readable format.

Showing the total number of pending events will also be useful.
