Thanks for your question. I think you may have stumbled across a bug. Can you please file a support ticket for this case?
So this is the difference between those two metrics:
We are querying two different objects in the NetApp API:
For Ops Per Sec - Object: cifs_ops Metric: total_ops 8B RAW NONE Total number of SMB operations since filer was started CM_DIAG
For CIFS Total Ops/sec - Object: cifs Metric: cifs_ops 8B RATE PER_SEC Total number of CIFS operations per second CM_BASIC
I think the bug is that we are treating both as pure counters, when one is actually just a pure counter and the other is a rate. In this case, I would trust Ops Per Sec and not CIFS Total Ops/sec.
Also, it looks like there may be a problem with the way we calculate the "others" (i.e. non-Read/Write) metric. Like I said,to verify this, please submit a ticket and we can verify from your diagnostics exactly what the root cause is. Sorry for the inconvenience.
Regarding what may be causing the spike in CIFS ops (regardless of the number) in the "other" category, it could be either antivirus or File Analysis if you have that enabled in Storage Manager.
