Disk I/O SNMP monitoring cluster mode

Hello there,

I am having trouble monitoring disk read/write + network received/sent via SNMP on cluster mode.

Looking into the documentations, I notice that there are some OIDs that will meet my requirement. However, they are not supported under cluster mode.

miscNetRcvdKB 1.3.6.1.4.1.789.1.2.2.2.0
miscNetSentKB 1.3.6.1.4.1.789.1.2.2.3.0
miscHighDiskReadBytes 1.3.6.1.4.1.789.1.2.2.15.0
miscLowDiskReadBytes 1.3.6.1.4.1.789.1.2.2.16.0
miscHighDiskWriteBytes 1.3.6.1.4.1.789.1.2.2.17.0
miscLowDiskWriteBytes 1.3.6.1.4.1.789.1.2.2.18.0

Note: no results are returned when I run a snmpwalk on them whilst other OIDs are working such as:

nodeName 1.3.6.1.4.1.789.1.25.2.1.1

Thanks!

Hi,

Yes, your observation is correct. SNMP has very limited MIBs exposed for cDOT (Unlike 7-mode). Most of the performance related metrics are accessed through 'ontap API' in cDOT. You may be aware - NetApp has a in-house Monitoring tool called 'OnCommand Unified Manager/Active IQ Unified Manager', this is a free tool does a good job in monitoring both health & performance related metrics (latency/IOPS/MBps/CacheMissRatio/Available_IOPs/Utilization/Perf.CapacutyUsed etc).

Thanks!
