Mayank Jain commented on ATLAS-4297:
------------------------------------
[~dharshmk] ,
This is not a bug, since by design the metrics shown on UI are maintained
in-memory, so after restart the data gets reset. Using appropriate Sink
implementation, we can persist it to storage like graphite, etc.
For reference :
