Bug in pnp template.
by dannyvz, October 31, 2015
When i use the template i get the message "Undefined offset: 2"

Found out that you need to change the following line:
$def[2] .= "DEF:cputime=$rrdfile:$DS[3]:AVERAGE " ;

To
$def[2] = "DEF:cputime=$rrdfile:$DS[3]:AVERAGE " ;

Checks with 'OK' status will return no performance data
by Lang, April 30, 2014
The plugins well but contains a syntax flaw which causes it to NOT return performance data if the check returns an 'OK' status. You will need to correct the following line to allow for performance data on all returns (Critical, Warning & OK). If you don't need trending data of when the return is 'OK', then you have nothing to change. In my environment I would like to see the entire trend, not just the few spikes of when a process goes hot.

Original Line:
echo "OK - ${output} | ${perfdata} ]"

Modified Line to allow perf data:
echo "OK - ${output} | ${perfdata}"

Great, but can't get perf graphs to work
by Admin_UCOP, July 31, 2013
The stats are working, but for some reason I just can't seem to figure the issue with the performance graphs. Saved the .php template, named the command after the template and still no graphs. I also re-checked the actual php template and it looks legit to me. Anybody else had this issue?
