Hi All, I am have rcently upgraded my nagios from 1.3 to 2.2, and am having trouble with nagiosgraph's insert.pl ever since. If I set up my process-service-perfdata command like so: define command{ command_name process-service-perfdata command_line /usr/bin/printf "%b\n" "$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$" >>/var/log/nagios/service-perfdata.out } I get lovely lines of perfomance data, and can run these lines as a parameter to the insert.pl script like so and it logs the data in the appropriate rrd, and nagiosgraph.log (logging is turned on in the script). sudo -u nagios /path/to/insert.pl "1146750185||printer||PING||OK - <a href="http://192.168.0.200"> 192.168.0.200</a>: rta 27.302ms, lost 0%||rta=27.302ms;100.000;500.000;0; pl=0%;20;60;;" or su - nagios /path/to/insert.pl "1146750185||printer||PING||OK - <a href="http://192.168.0.200">192.168.0.200 </a>: rta 27.302ms, lost 0%||rta=27.302ms;100.000;500.000;0; pl=0%;20;60;;" However, with my process-service-perfdata command set to this: define command{ command_name process-service-perfdata command_line /usr/lib/nagios/nagiosgraph/insert.pl "$LASTSERVICECHECK$||$HOSTNAME$||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$" } no rrds are updated, and nothing appears in the nagiosgraph.log. Firstly, has anyone had a similar problem with performance data in general, and secondly, can anyone see anything obviously wrong in what I have done? Googling has gotten me nowhere, the manual has put me on the right track in a lot of ways, but I can't fathom why the script is, apparently, not being run by the daemon. Thanks in advance. John
