BadlyPerformingDisks-Check

Checks the number of badly performing (=highly utilized) disks.

Usage

$ check_netapp_pro.pl BadlyPerformingDisks -H <host> [...][ --highly_utilized=n% ] [--help]

Description

This plugin checks firstly the disk-usage per disk. Than it counts the number of disks, which are highly utilized. What exactly we consider to be a high utilization, is set by the option --highly_utilized.

An alarm is output, if the number of badly performing disks exceeds a given percentage-threshold.

If you would like to check the usage per disk you should use the PerfDisk plugin.

Simple Examples

[S1] ./check_netapp_pro.pl BadlyPerformingDisks -H filer -w 85 -c 95 --highly_utilized=90

Checks all disks - warns if more than 85% of the disks are highly utilized (=have a utilization of more than 90%).

[S2] ./check_netapp_pro.pl BadlyPerformingDisks -H filer -w 85 -c 95 --highly_utilized=80

Same as above, but we consider a disk to be highly-utilized if it has a utilization of more than 80%.

[S3] ./check_netapp_pro.pl BadlyPerformingDisks -H filer -w 75 -c 90 --highly_utilized=90

Checks all disks - warns if more than 75% of the disks have a utilization of over 90%.
