perfdata pnp4nagios tweak
by agentdavidson, April 30, 2017

I found I had to add a 'space' in the perfdata print statement in order for pnp4nagios to process the perfdata correctly -$perfdata = sprintf("| SessActive=%s,SessMax=%s,SessFail=%sn", +$perfdata = sprintf("| SessActive=%s, SessMax=%s, SessFail=%sn", Thanks


works well - I have a patch to include Session Fails and perf data

Works fine

Plugin works fine. The diff works well too. (Juniper SSG).


Very useful
by svindler, March 31, 2013

Works fine. I have used on a Nagios Core running on Ubuntu, and on Nagios XI running on centos. I made the following change for Nagios XI to automatically create graphs: 143c143 $answer = sprintf("host '%s', sessions : %s/%s (%2.2f%%)|Current=%s;Maximum=%sn", 147c147,149 $session_used, > $response->{$snmpnsResSessActive}, > $response->{$snmpnsResSessMaximum}
