    • Release Note:
      Changed capacity scheduler UI to better present number of running and pending tasks.

      Description

      The UI for capacity scheduler displays 'pending tasks' counts. However the capacity scheduler does not update these counts to be the actual values for optimization purposes, for e.g. to avoid walking all pending jobs on all heartbeats. Hence this information is not very accurate.

      Also, while 'running tasks' counts are useful to compare against capacities and limits, 'pending tasks' counts do not add too much user value. A better count to display would be the number of running and pending jobs.
