From what I understand it's all about what is returned by the check back to nagios. See this topic http://support.nagios.com/forum/viewtop ... graph#p263
I've tried duplicating a service and changing the check command but I don't get a performance graph.Admin said:
When on the detail page, click the "Advanced Tab". If the performance data line is empty, there isn't anything that can be used to generate a performance graph.
For example, this known service "'Paging File usage" check seems to generate a graph.
So I duplicated the service and customised it so it looked at a different counter and gave it differernt -w and -c values. However no graph is being generated. The particulars are:
$USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$ $ARG3$
$ARG1$ = COUNTER
$ARG2$ = -l "\\Memory\\Committed Bytes","Committed Bytes is %.f " -w 1171330000.0 -c 1491330000.0
So looking at the original service that generates a graph, I look at the performance data line:
'Paging File usage is %.2f %%'=53.080000%;70.000000;90.000000;
Then I look at my service and it's performance data line is:
'Committed Bytes is %.f '=1153570000.000000%;1171330000.000000;1491330000.000000;
So what am I doing wrong here, what else do I need to do for performance graphs to appear?
