Oops, Looks like i had an error in my configuration file. Next question: Any idea why check_nagios can't find the running process? $/usr/lib/nagios/plugins/check_nrpe -H 10.10.10.41 -c check_nagios NAGIOS CRITICAL: Could not locate a running Nagios process! Nothing in /var/log/nagios2/nagios.log about this message. I can verify the nrpe and nagios are working as the following command returns succesfully. $ /usr/lib/nagios/plugins/check_nrpe -H 10.10.10.41 -c check_load OK - load average: 1.00, 1.04, 1.05|load1=1.000;15.000;30.000;0; load5=1.040;10.000;25.000;0; load15=1.050;5.000;20.000;0; Thanks, JJ <div class="gmail_quote">On Mon, Jun 15, 2009 at 1:10 PM, Jeremiah Jester <<a href="mailto:jeremiahjester@gmail.com">jeremiahjester@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hello Nagios Users, I'm attempting to setup a second nagios server up to do failover monitoring in case my primary nagios server goes down. Running into a odd problem in talking to the nrpe daemon on the master server..... When I run the following cmd prompt, nrpe does not allow me to connect from the new host even though it is specified in the master nagios server nrpe.cfg file. SLAVE$ /usr/lib/nagios/plugins/check_nrpe -H 10.10.10.41 -c check_load Connection refused by host However, when i run the same cmd for another host, it returns successfully. SLAVE:~$ /usr/lib/nagios/plugins/check_nrpe -H 10.10.10.43 -c check_load OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0; **Note thta the IP for the nagios failover server IS listed in the nrpe.cfg allowed_hosts directive and the nrpe daemon has been restarted. Any insight on this issue? I am running Nagios 2.11. Thanks, JJ </blockquote></div>
