Description Mohit Agrawal 2021-02-15 11:03:47 UTC

Added latency tracking of rpc-handling code. With this change we
should be able to monitor the amount of time rpc-handling code is
consuming for each of the rpc call.

After merging this patch we can easily measure latency at rpc level on the brick side.

Comment 1 Mohit Agrawal 2021-02-15 11:06:27 UTC

The patch is helpful to track performance issue in the customer environment so i would
like to consider this for 3.5.5.There is no specific testing required, only need to generate
the statedump to verify the patch.

The patch is already merged in upstream

Thanks Mohit for walking through the patches and clarified the possibility of regression and
stability of the fix. That helped QE to accept this bug for 3.5.5
