check_diskio.ps1

Project Notes

powershell script to get all disks iops & bytes/s activity in one check.
can be used with nrpe & nsclient and offers graph metrics.

uses windows performance counters. since these are OS language dependent, you might adapt the script if you use a non en-us OS.

nsclient.ini config requirements:
[/settings/NRPE/server]
allow arguments = true
allow nasty characters = true
[/settings/external scripts]
allow arguments = true
[/settings/external scripts/scripts]
check_diskio = cmd /c echo scriptscheck_diskio.ps1 -show "$ARG1$"; exit($lastexitcode) | powershell.exe -command -
