Nrpe needs to be running on the remote box.<o:p></o:p> <o:p> </o:p> So if you wanted to check_disk on the linux box, you want nrpe on, and chkconfig it on so it always starts. Open nrpe.cfg and edit the check_disk check to your liking, make sure nrpe.cfg includes the ip address of your Nagios Host box to allow check_nrpe to call it.<o:p></o:p> <o:p> </o:p> To get the variables you can add, you’d do ./check_disk –help in the plugins directory (something like /usr/lib/nagios/plugins)<o:p></o:p> <o:p> </o:p> I’m rather new as well, but that’s my understanding.<o:p></o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='margin-left:.5in;text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: nagios-users-admin@lists.sourceforge.net [mailto:nagios-users-admin@lists.sourceforge.net] On Behalf Of Dimitri Yioulos Sent: Tuesday, November 23, 2004 3:01 PM To: nagios-users@lists.sourceforge.net Subject: Re: [Nagios-users] Some things don't work<o:p></o:p> </div> <o:p> </o:p> I use NSClient to monitor Windows, my check_command looks like:<o:p></o:p> define command{<o:p></o:p> command_name check_nt_disk<o:p></o:p> command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 5668 -v <o:p></o:p> USEDDISKSPACE -l $ARG1$ -w $ARG2$ -c $ARG3$<o:p></o:p> }<o:p></o:p> <o:p> </o:p> In services it's defined as:<o:p></o:p> define service{<o:p></o:p> use generic-service<o:p></o:p> host_name xone,xthree,xfour<o:p></o:p> service_description check_nt_disk<o:p></o:p> is_volatile 0<o:p></o:p> check_period 24x7<o:p></o:p> max_check_attempts 3<o:p></o:p> normal_check_interval 5<o:p></o:p> retry_check_interval 1<o:p></o:p> contact_groups Test-Admins<o:p></o:p> notification_interval 120<o:p></o:p> notification_period 24x7<o:p></o:p> notification_options c,r<o:p></o:p> check_command check_nt_disk!c!90!95<o:p></o:p> }<o:p></o:p> <o:p> </o:p> <o:p> </o:p> Jan,<o:p></o:p> <o:p> </o:p> I followed the directives in you post, as per the above, and … it works! Many thanks to you.<o:p></o:p> <o:p> </o:p> Now, I don’t want to appear lazy; I’ve done my best to get the nrpe piece configured properly. I should say that I’ve used the Dag Wieers rpms to install nagios, nagios-plugins-nrpe, and nagios-nrpe (I don’t know the difference between the last two). Once again, at least afaic, the documentation isn’t that good. So, I’m going to push my luck and ask:<o:p></o:p> <o:p> </o:p> Do I have to add anything nrpe-related to the client machines? What directives must I add to what files on the nagios server? I’d like to start out by monitoring Current Users, Total Processes, and Disk Free Space. All of these boxes are Linux.<o:p></o:p> <o:p> </o:p> I’m real close here.<o:p></o:p> <o:p> </o:p> Dimitri<o:p></o:p> <o:p> </o:p> </div> </body> </html>
