Perl script that uses SNMP (via snmpget) to get disk usage information from Windows hosts. Outputs usage %, total, used and free space in human-readable format with auto-scaling (KiB up to TiB).

Based on the check_win_snmp_disk.pl script posted here by jakubowski Benjamin, this enhanced version: * prints usage information if incorrect parameters are given * handles exceptions (more) gracefully * automatically scales output to TiB, GiB, MiB or KiB I have tested this updated script against Windows 2003 server (including R2) only, but it should work with most windows hosts.
I added the magic threshold adaption from check_mk for large disks to the script. https://github.com/pashol/nagios-checks/blob/master/check_win_snmp_disk.pl Documentation for the magic number: https://mathias-kettner.de/checkmk_filesystems.html (Chapter df magic number) I also eliminated the rounding of percentages. For large disks with a narrow warning/critical levels it could potentially cause problems.
It works great on systems with multiple drives.
Here is an update made by Alexander Tikhomirov: 1) add performance data 2) cosmetic changes http://pastebin.com/MFBeNkiK
The script reports the D drive when specifying the parameter number 2 which is for the C drive on certain servers. For example - on one Windows 2003 machine, specifying a parameter of 2 for the C drive yields a reading from the script of the D drive.
Effortless Plugin. ./check_win_snmp_disk.pl 10.0.64.173 public 2 80 90 OK : Percent Used : 33%, Total : 33.8 GiB, Used : 11.2 GiB, Free : 22.6 GiB
