> following metrics are being implemented, including but not limited to:
> Worker:
> # Kill Count by Category - Assignment Change/HB too old/Heap Space
> # Time spent in each state
> # Time to Actually Kill worker (from identifying need by supervisor and
> actual change in the state of the worker) - per worker?
> # Time to start worker for topology from reading assignment for the first
> time.
> # Worker cleanup Time/Worker cleanup Retries
> # Worker Suicide Count - category: internal error or Assignment Change
> Supervisor:
> # Supervisor restart Count
> # Blobstore (Request to download time)
> - # Download time individual blob (inside localizer) localizer gettting
> requst to actually download hdfs request to finish
> - # Download rate individual blob (inside localizer)
> - # Supervisor localizer thread blob download - how long (outside
> localizer)
> # Blobstore Update due to Version change Cnts
> # Blobstore Storage by users
> There might be more metrics added later.
> This patch will also refactor code in relevant files. Bugs found during the
> process will be reported in other issues and handled separately.
