<div>Hi John,</div> <div> Your problem is that you're trying to invoke a service that is not local, thus it shouldn be defined not only in your Nagios server configuration files, but also in the nrpe.cfg file used when the nrpe daemon starts on the target machine. </div> <div> I'll try to explain just a little bit what I did since I suffered the same situation:</div> <div> </div> <div> 1) Define a new service in Nagios Engine for monitoring non-local disks, as follows:</div> <div> </div> <div><FONT size=1>define service{</FONT></div> <div><FONT size=1> use local-service ;Name of service template to use</FONT></div> <div><FONT
size=1> host_name <EM>[the servers in which you have nrpe installed]</EM></FONT></div> <div><FONT size=1><EM> </EM>service_description Remote check disk</FONT></div> <div><FONT size=1> check_command check_nrpe!check_hda1!20%!10%!/</FONT></div> <div><FONT size=1>}</FONT><BR></div> <div> 2) I used check_hda1 instead of check_disk to identify the way I use this in the target machines. Then you need to include this type of call in your target machine's nrpe.cfg file, as follows (at the very end):</div> <div> </div> <div><FONT size=1># The following examples use hardcoded command arguments...<BR>command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p /dev/hda1</FONT><BR></div> <div>
This way, nrpe tells the target machine to call it's /usr/local/nagios/libexec/check_disk command when the Nagios core engine calls check_nrpe!check_hda1 on this target machine.</div> <div> </div> <div> Hope it helps, and most important that you understand what I tried to tell you ;-)</div> <div> Regards,</div> <div> </div> <div> </div> <div>Sebastian Ganame</div> <div> </div> <div> </div> <div class=MsoPlainText style="MARGIN: 0in 0in 0pt"><FONT face=Verdana>-----Original Message-----<BR>From: nagios-users-bounces@lists.sourceforge.net [mailto:nagios-users-bounces@lists.sourceforge.net] On Behalf Of Jonathan Murray<BR>Sent: Miércoles, 30 de Mayo de 2007 07:49 p.m.<BR>To: nagios-users@lists.sourceforge.net<BR>Subject: [Nagios-users] NRPE: Command 'check_disk' not defined</FONT></div> <div class=MsoPlainText style="MARGIN: 0in 0in 0pt"><?xml:namespace prefix = o ns =
