I would like to submit this to the original author, but I created this instead.

Check free space on windows partitions. It tries to resemble as much as possible with check_disk from the Official Nagios Plugin package.

** Modified Barry W. Alder 2013/09/24
changed code so that an error is reported if no disks are found with the /x flag and an error is reported if the disk specified in the /d flag is not found



It checks all partitions, a list or all but an exclusion list.
Limits can be in % or in standard units (B | kB | MB | GB)

Results are displayed in standard Nagios format.

nrpe.cfg config file declaration:
command[check_disk]=c:Windowssystem32cscript.exe //NoLogo //T:10 c:adminnrpecheck_disk.vbs /w:$ARG1$ /c:$ARG2$ /p /d:$ARG3$ /x:$ARG4$ /u:GB

Connand line syntax:
cscript //Nologo check_disk.vbs /w:INTEGER /c:INTEGER [/p] [/d:DRIVE_LIST | /x:DRIVE_LIST] [/u:UNITS] [/h]

/w: warning limit

/c: critical limit

/p: limits in %, otherwise in UNITS

/d: included drives list

/x: excluded drives list

/u: B | kB | MB | GB, default MB

/h: this help
"!!!!!You MUST specify a drive list or ALL for the /d parameter. If not the script will give no output!!!!!"
check_disk.vbs /w:15 /c:5 /p /d:CDE /u:kB - result will be displayed in kB, limits are in percents

check_disk.vbs /w:500 /c:250 /d:ALL - result will be displayed in MB, limits are in MB, all fixed drives
check_disk.vbs /w:500 /c:250 - result will be displayed in MB, limits are in MB, all fixed drives
