[jira] [Created] (KUDU-2705) /scans should show more useful time metrics

Adar Dembo created KUDU-2705:
--------------------------------

             Summary: /scans should show more useful time metrics
                 Key: KUDU-2705
                 URL: https://issues.apache.org/jira/browse/KUDU-2705
             Project: Kudu
          Issue Type: Bug
          Components: supportability, ui
    Affects Versions: 1.9.0
            Reporter: Adar Dembo


Currently /scans shows the monotonic time since a scan started as well as its "duration", which is the total amount of wall time for which a scanner was live.

We should also publish other useful time metrics, like:
 * cumulative CPU time
 * cumulative I/O time
 * a second wall time, including all time spent by the tserver servicing a scan (maybe that's just a sum of CPU and I/O time above?)
