A Message From The Founder...

As the founder of Nagios, I'm asking for your help in a cause that's dear to my heart.

I'm launching a new project to help better the world by providing the information, ideas, and inspiration that I believe can improve the lives of people everywhere.

I know you're busy managing networks, but I would appreciate it if you would consider liking my Facebook page and showing your support for the content and messages I produce by sharing them with your friends and family.

You can learn more about my project by visiting ethangalstad.me/nagios. Thank you for your time. I wish you all the best in your endeavors, whatever they may be.

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.

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

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.
