Mudit, can you please take a look at the 4.9 branch PR: https://github.com/red-hat-storage/ocs-operator/pull/1842 
It should be good to go... Let me know if any has to be done from my end

Done
Comment 18 Ramakrishnan Periyasamy 2022-12-06 15:50:51 UTC 
Observed IOPS, Throughput and Used Capacity values in Performance card are closely matching with StorageSystems Block and File card.
But there were around ~2ms Latency difference between those 2 pages which is big difference.

After discussion with Arun came to know about comment https://bugzilla.redhat.com/show_bug.cgi?id=2026144#c20 that value calculation of those params are using different queries and timeline and due to that there is a difference expected, so according to this comment moving this BZ to verified state.

Also Opened new BZ https://bugzilla.redhat.com/show_bug.cgi?id=2151291 to track the value mismatch issue mentioned in comment https://bugzilla.redhat.com/show_bug.cgi?id=2026144#c20

Note: 
1. During this test ran some IO 
2. Updated chart values for 24hrs in Performance and StorageSystems Block and File card
3. Took one specific time eg: 10.03 and gathered values for all mentioned params in 1st line 
4. Values are not exact but its closely matching, even time is not exact its +/- 0.02
