[Nagiosplug-help] Trouble with Nagiosgraph

[Ralph.Grothe at itdz-berlin.de]

Hi Peter et al.,

sorry for the late reply.

But I have a good excuse because I attended this year's
Nagios-Konferenz at Nürnberg last Thursday and Friday.
http://www.netways.de/de/nagios_konferenz/

It was great meeting the Nagios experts there and even a few I
already knew from this mailing list.

But as for my problem with Nagiosgraph.

It looks as though I defined an incorrect data template (only
four fields instead of five)
and forgot the $SERVICEOUTPUT$ field.
Thus my map regex never matched the perfdata: string why no RRD
file has been generated at all.

I could easily verify this in a Perl Debugger session.


  DB<5> p $data
1192456552||arno||icmp-host-alive||rta=2.098ms;1000.000;10000.000
;0; pl=0%;50;80;;

  DB<6> l
52==>     my @d = split( /\|\|/, $data);
53:       return ( lastcheck    => $d[0],
54                 hostname     => $d[1],
55                 servicedescr => $d[2],
56                 output       => $d[3],
57                 perfdata     => $d[4],
58               );
59      }
60 
61      # Write debug information to log file
  DB<6> .
main::parseinput(/usr/lib/nagios/nagiosgraph/insert.pl:52):
52:       my @d = split( /\|\|/, $data);

  DB<6> n
main::parseinput(/usr/lib/nagios/nagiosgraph/insert.pl:53):
53:       return ( lastcheck    => $d[0],
54:                hostname     => $d[1],
55:                servicedescr => $d[2],
56:                output       => $d[3],
57:                perfdata     => $d[4],
58:              );
  DB<6> x @d
0  1192456552
1  'arno'
2  'icmp-host-alive'
3  'rta=2.098ms;1000.000;10000.000;0; pl=0%;50;80;;
'



And here is my wrong template definition in nagios.cfg


# grep \|\| /etc/nagios/nagios.cfg
service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$||$S
ERVICEDESC$||$SERVICEPERFDATA$

So changing to

# grep -n \|\| /etc/nagios/nagios.cfg
694:service_perfdata_file_template=$LASTSERVICECHECK$||$HOSTNAME$
||$SERVICEDESC$||$SERVICEOUTPUT$||$SERVICEPERFDATA$

and restarting nagios almost immediately created the RRD files.


Nevertheless, I got so many inspirations from the conference.
So I am yet not sure whether to shift to PNP.
The only thing I would consider a degradation with this
was that it is based on PHP and I daresay that any Perl hack is
far superior to any PHP candy.
Also because of custom regex one can put in the map file,
with Nagiosgraph I don't even need a plug-in to conform to the
official guidelines how to 
display perfdata but can match any sort of output easily.
But that's my own bias.

Rgds.
Ralph
