I am setting up an internal lab where I have a couple of FAS clusters and an instance of Active IQ Unified Manager. I am generating I/O in one of the volumes:
POC-filer::> statistics volume show -vserver svm-cifs -volume RH -interval 5 -iterations 11
POC-filer : 10/31/2019 07:41:26
*Total Read Write Other Read Write Latency
Volume Vserver Ops Ops Ops Ops (Bps) (Bps) (us)
------ -------- ------ ---- ----- ----- --------- ----- -------
RH svm-cifs 1762 1762 0 0 114690048 0 1998
POC-filer : 10/31/2019 07:41:30
RH svm-cifs 1481 170 1288 22 11059200 83812352
But Unified Manager will never show the performance information (latency, IOPs and MBps), it only show "No data to display. (See screenshot). I've tried some KBs already but problem persists.
Any ideas what may cause this?
it could be:
But i suggest you collect support bundle and open a case so it's properly investigated. the performance part of active IQ is actually a separate component that only integrated into the same product few years back, so from that screenshot seems that it can also just be something broken in the communication between the two products.
Thanks for your input. But heavy load should not be a problem here. I am in a lab environment and neither the storage systems nor the OCUM VM are under heavy load. All I have is a windows client generating disk IO in a CIFS volume.
