The performance data can be found in the output of the plugin, if the plugin supports it. There are two types of output actually. The first part before the pipe is handled as "output", this will be shown in your Nagios UI and in notifications. The second part behind the pipe is handled as "performance data". With this data you'll be able to generate graphs. See here for an example with check_ping: # ./check_ping -H <a href="http://google.com">google.com</a> -w 20,50% -c 50,70% PING OK - Packet loss = 0%, RTA = 15.99 ms|rta=15.987000ms;20.000000;50.000000;0.000000 pl=0%;50;70;0 Everything behind the pipe is performance data. <div class="gmail_quote">On Sun, Apr 8, 2012 at 5:28 PM, <<a href="mailto:asmith@dms.cat">asmith@dms.cat</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, I'd like to be able to log performance data from Nagios but I have a couple of doubts. First and most fundamental, will I be able to use the normal Nagios perfdata support with passive NSCA clients? Secondly, I have been reading the documentation, ie <a href="http://nagios.manubulon.com/traduction/docs14en/perfdata.html" target="_blank">http://nagios.manubulon.com/traduction/docs14en/perfdata.html</a> And it says that a plugin must return additional data after a pipe "|" sign for Nagios to accept any perforamnce data from that plugin. I was having a look at the standard plugins and they don't seem to have any support for performance data, ie: # ./check_ping check_ping: Could not parse arguments Usage: check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>% [-p packets] [-t timeout] [-4|-6] There is no option to enable performance data in the plugin output. Am I getting this wrong or do none of the standard plugins allow any performance data capture? thanks in advance!
