Get “disk utilization” from a NetApp filer via SNMP

netappsnmp

On a NetApp filer's command line I'm running "sysstat -u" to show disk utilization, (actually the utilization of the single busiest disk). By disk utilization, I mean "percent of time the disk is busy", not "how much space on the disk is being used to store data/metadata".

Is there a way to get disk utilization info through SNMP? The netapp.mib file doesn't appear to expose this. It does have CPU utilization, disk usage & capacity information, etc, but not disk utilization. The MIB-II (rfc1213) seems to be the only other information exposed by the filer through SNMP. I hope I am missing something.

The "CP (consistency point) time" metric is exposed through the NETAPP-MIB in SNMP, but this seems to only partially correlate with disk utilization under write load, and not really at all under read load.

Best Answer

Disk utilization as reported by sysstat is not exposed through SNMP.
