Due to a customer request, we would like to show how the switch --perfdata_uom_string can be used in situations where monitoring systems have issues with unit of measurement (UOM) strings (the unit for performance data) and can not be displayed properly.
For example, if the WAFL check returns the CP counter per second …
On some occasions, one might not want to collect all counters from the filer. This does not happen very often, but there are at least two cases where it is required or in the very least useful to exclude a specific counter:
If counters are not available in an older version of DataONTAP: our tests for PerfDisk after the …
PerfVolume will soon receive a new switch in order to calculate and check the average of all volumes (useful for latency for instance) or the the sum of all volumes (for total_ops for instance_)._ check_netapp_pro.pl PerfVolume -H _filer_ -z _counter_ --math=average|total Please refer to the help page of PerfVolume to …
The Input-/Output Operations per Second (IOPS) or Operations per Second (OPS) can be monitored on various levels:
System Operations (total_ops) This is why the counter total_ops in the PerfSys check exists. Unfortunately, this counter is deprecated and will no longer be supported by NetApp in new versions of DataONTAP. …
PerfDisk measures disk_busy for each disk. Using ‑‑raid_group disks of a specific aggregate can be monitored. Recently we added the possibility to monitor the average utilization, measured for all disks (‑‑average ). In combination with ‑‑raid_group an average value of disk_busy can now be measured and monitored for …
The usage for each processor can be monitored with PerfCpu. Not long ago we received a request to monitor the average CPU usage (for all CPUs). If Prozessor0 has a usage of 40% and Prozessor1 a usage of 80%, the check in this mode would return OK up to a threshold of 60% (average of 40 and 80). This option will be …
Version 3.0.7 of our Monitoring Plugins for NetApp (check_netapp_pro) will be available soon and will include a number of new features that have been implemented based on feedback we received from our customers:
New Check PerfSys: Not entirely new, but taken over from the stable version 2.x to version 3.x. In this new …
