I'm new to c-mode, unified manager, & perf. manager.
I have a FAS2552.
I'm running 8.3.2
I have one volume (approx 200GB) used for NFS on the cluster with not many IOPS.
I'm getting latency alerts in performance manager for the following policy:
-------------------------
Object Type: Volume
Object Counter Condition* Avg Latency ms/op Warning: 20 Critical: 30
Thresholds must be crossed for at least* 5 Minutes
----------------------------
The volume is reporting critical errors because the latency ms/op for this volume averages 274 with a high of 743.
I break down the details and discover that the source of the latency is being caused by the 'Network Processing' Cluster component. All other components are contributing 0 to the latency.
My read/write latency is < 0ms
IOPS avg around 100.
Thoughts?
(CPU isn't doing anything either.)
