Re: [Nagios-users] Trying to figure out the PCRE expression for Nagiosgraph Map
OK. So to make more sense of the whole thing, the only thing that is taken into account is the actual numerical value? In other words, it's automatically parsed? This is what I wasn't sure of. Here is the entry in the mapfile I was using: I guess the reason I'm having issues with this is the following snippet from the nagiosgraph.log: Fri May 10 12:57:51 2013 insert.pl warn output/perfdata not recognized: hostname:mymachine servicedesc:Apache Processes output:PROCS OK: 11 processes with args apache perfdata: the problem is there is no perfdata and the rrd file isn't being populated, (and obviously, no graph). I'm attributing this to the fact that the map file entry is wrong. This is really where my problem lies. Am I looking in the wrong place? Thanks.

Here is the entry in the mapfile I was using: /output:PROCS.*:(\d+) processes with args 'apache'/ and push @s, ['apache', ['connections', GAUGE, $1] ]; This works, too, when you only want to parse the process checks for apache. You give the RRD description the name connections. I don't think that the number of Apache processes really represent the number of connections. In this case, I suggest you use check_netstat.pl. the problem is there is no perfdata and the rrd file isn't being populated, (and obviously, no graph). I'm attributing this to the fact that the map file entry is wrong. This is really where my problem lies. Am I looking in the wrong place? It's check_procs which doesn't create perfdata. You might need to manually patch it.
