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 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}
