do you have the extended output enabled for your check command as per the doc says( that is output after the | symbol ).. <div class="gmail_quote">On Thu, Jun 9, 2011 at 10:00 PM, Tristan Drinkwater <<a href="mailto:tristand@micro-p.com">tristand@micro-p.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div link="blue" vlink="purple" lang="EN-GB"> <div> Hi guys, I’ve followed the install instruction from here (<a href="http://docs.pnp4nagios.org/pnp-0.4/install" target="_blank">http://docs.pnp4nagios.org/pnp-0.4/install</a>) to install pnp4nagios v4 on my nagios 3.x running on a fedora 14 box but I’m stuck when verifying the install. When I do <a href="http://servername/Nagios/pnp" target="_blank">http://servername/Nagios/pnp</a> my first error is ‘Hostname is not set’ followed by ‘perfdata folder is empty’ and ‘no rrd files’ I’ve looked and sure enough there are no rrd files in the folder, plus there is no entry in the log file. To me this suggests that Nagios isn’t firing the command ‘process-service-perfdata’ after completing a check. My commands.cfg file looks correct; # Added by Tristan for PNP 4 Nagios define command { command_name process-service-perfdata command_line /usr/local/nagios/libexec/<a href="http://process_perfdata.pl" target="_blank">process_perfdata.pl</a> } define command { command_name process-host-perfdata command_line /usr/local/nagios/libexec/<a href="http://process_perfdata.pl" target="_blank">process_perfdata.pl</a> -d HOSTPERFDATA } And so is my Nagios.cfg file; process_performance_data=1 host_perfdata_command=process-host-perfdata service_perfdata_command=process-service-perfdata these tow are the only things I’ve changed from the default install. Any ideas what I’ve missed?? Any tips on how I can drill down further to see what’s not happing and why? Thanks in advance J Regards, Tristan Drinkwater </div> <hr> Micro Peripherals Limited.
