Doc Text:

.Ceph node Network Packet drop alerts are shown appropriately on the Ceph dashboard Previously, there was an issue in the query related to Ceph node Network Packet drop alerts. As a consequence, those alerts would be seen frequently on the Ceph Dashboard. With this fix, related query no longer causes the issues and Ceph node Network Packet drop alerts are shown appropriately.

Description of problem:
[ceph-Dashboard] RHCS 6.0 - Ceph node Network Packet drop alerts are  seen frequently in RHCS 6.0 dashboard 

Version-Release number of selected component (if applicable):
ceph version 17.2.3-21.el9cp (c988b360f12cbb4bc1c80ee7a9771814bc0f49d6) quincy 

How reproducible:


Steps to Reproduce:
1. Have a cluster with 5.2 and perform upgrade to 6.0 with 250+images across pools cluster with 60+ filled (OS is upgraded from 8.6 to 9.0 before performing ceph upgrade to 6.0)
2. once upgrade is successful check the dashboard alerts section
3. Observe the behaviour 
We see continuous popups throwing "Network packet drop alerts" in RED in alert sections

NOTE: cluster health status was good and there was no significant network related errors in the ceph status

Actual results:
We are seeing continuous network packet drop errors in the ceph dashboard alert section

Expected results:

We should not see any network related alerts with packet drops
