check_csv_freespace.ps1 for MS HyperV

Project Notes

as your Cluster Shared Volume (CSV) is mounted as c:ClusterStorage<CSV-Name> there's no easy way to check if your Storage is running out of diskspace

the script returns status as well as perf-data

running the script on the hyperv-host:

.check_csv_freespace.ps1 -n <CSV-Name> -w 80 -c 90
e.g.: .check_csv_freespace.ps1 -n csv1-scsi -w 80 -c 90

how to use with nagios:

* copy the script to your nsclient++ directory
* add command alias to nsc.ini
* command[check_csv_freespace]=cmd /c echo .check_csv_freespace.ps1 -n $ARG1$ -w $ARG2$ -c $ARG3$ | powershell.exe -command -
* set allow_arguments=1
* restart nsclient++ service
* add nagios command

define command {
command_name check_hyperv_csv_freespace
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_csv_freespace -a $ARG1$
}

* add nagios service check

define service{
use remote-service
hostgroup_name hyperv-hosts
servicegroups hyperv-services
service_description Cluster: CSV1-SCSI free disk space
check_command check_hyperv_csv_freespace!csv1-scsi 80 90
}
