The nrpe.cfg file on ns2 has this relevant entry: (this server correctly reports 1 user logged in) command[check_users]=/usr/local/nagios/libexec/check_users -w $ARG1$ -c $ARG2$ Now, I stay logged into ns2 (<a href="http://207.158.10.18">207.158.10.18</a>), and then from the nagios server I execute the command: [root@dev2 nagios]# ./libexec/check_nrpe -H <a href="http://207.158.10.18">207.158.10.18</a> -c check_users -a 1 1 USERS OK - 0 users currently logged in |users=0;1;1;0 I'm running running RHEL 4.6 on ns2, and the nagios server is running CentOS 4.5. How do I go about debugging this situation? --Gil <div class="gmail_quote">On Dec 11, 2007 10:53 PM, Olivier 'Babar' Raginel <<a href="mailto:nagios@babar.us">nagios@babar.us</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="Ih2E3d">On Tue, Dec 11, 2007 at 12:45:29PM -0800, Gil Vidals wrote: > root@ns2 nagios]# ./libexec/check_users -w 1 -c 1 > USERS CRITICAL - 1 users currently logged in |users=1;1;1;0 > However, running the same command from my nagios server, fails: </div>> [root@dev2 nagios]# ./libexec/check_nrpe -H [1]207.158.10.18 -c <div class="Ih2E3d">> check_users -a 1 1 > USERS OK - 0 users currently logged in |users=0;1;1;0 > This condition is only happening on two servers out of 30.

On the second test, I guess you're no longer logged in, thus the server is reporting no users are currently logged in, which seems fair to me. Anyway, having a look at your NRPE configuration might help, but from your output, everything looks fine to me. -- Babar. ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
