When I use the filesystems unstead of the mount points in the nrpe.cfg it works fine with disks 1, 2 and 3. The only disk that nrpe is not able to read is disk4 which is mounted on /vservers/fred/data. This is the version of nrpe I'm using: NRPE Plugin for Nagios Copyright (c) 1999-2006 Ethan Galstad (<a href="mailto:nagios@nagios.org">nagios@nagios.org</a>) Version: 2.5.1 Last Modified: 04-09-2006 License: GPL v2 with exemptions (-l for more info) SSL/TLS Available: Anonymous DH Mode, OpenSSL 0.9.6 or higher required The Nagios-plugins were installed using the rpm on the server I'm running the check against. I changed the nrpe.cfg for disk4 to the following: command[check_disk4]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /vservers/fred/data When I run /usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /vservers/fred/data from the monitored server it outputs the information fine. But when running ./check_nrpe -H <a href="http://my.server.com">my.server.com</a> -c check_disk4 from the Nagios server I get the following: DISK CRITICAL - /vservers/fred/data does not exist Is this a bug with nrpe? <div class="gmail_quote">On Jan 11, 2008 6:12 AM, Thomas Guyot-Sionnest <<a href="mailto:dermoth@aei.ca">dermoth@aei.ca</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On 10/01/08 05:25 PM, Jake Solid wrote: > *I'm getting the following message when monitoring one of my disks from <div class="Ih2E3d">> my nagios server.* > > DISK UNKNOWN - free space:| </div>Hi Jake, Can you tell me which version of check_disk you are using? Did you compiled Nagios-plugins on the server you're running the check against? The -p argument normally takes a mountpoint. Can you try with that? Can you also try running it as the same used NRPE is sunning as?
