Capturing perf data from check_snmp

[James Whittington]

I'm using Nagios version 1.3 with Plugins version 1.4-2 on a debian
sarge system.

I am using perfparse to capture performance data to mysql.

I am trying to capture an rfinput value of a wireless device through the
check_snmp plugin and write it to a mysql db for reporting.

 

Since check_snmp does not currently write performance data in the output
I was trying to write a simple perl script to use check_snmp but add the
performance data to the output.

To make a long story short my simple perl script is adding performance
data to the output and perfparse is picking it up, but I noticed that
the service status in Nagios is always "OK" even when the Status
Information says otherwise.

SNMP WARNING - *55* neg-dbm 

 

 

Here's how it looks through check_snmp

./check_snmp -H10.0.10.12
-oSNMPv2-SMI::enterprises.2378.1.1.2.1.2.80.1.1.3.5 -w 22:50

SNMP WARNING - *51*

 

Here's the modified output from the perl script that triggers perfdata
but kills status funtionallity in Nagios.  

./check_rfinput3 -H10.0.10.12

SNMP WARNING - *54* neg-dbm|rf-input=54

 

Here's the very very basic script that did the damage.

/usr/lib/nagios/plugins# more check_rfinput3

#!/usr/bin/perl

if ($ARGV[0] eq "") {

       print "Hostaddress required\n";

        print "ie.. script.pl 123.123.123.123\n";

}else{

        $HOSTADDRESS = $ARGV[0];

        $HOSTADDRESS =~ s/-H//;

$RFINPUT = `/usr/lib/nagios/plugins/check_snmp -H$HOSTADDRESS
-oSNMPv2-SMI::enterprises.2378.1.1.2.1.2.80.1.1.3.5 -w 22:48 -c 20:55 -u
neg-db

m`;

$RFRAW = $RFINPUT;

$RFRAW =~s/[^0-9]//g;

chomp($RFINPUT);

print "$RFINPUT|rf-input=$RFRAW";

}

 

 

 

 

 

I even tried to modify the check_snmp source code which fixed the status
info but did not get me perfdata for some reason.

./nagios-plugins-1.4/plugins/check_snmp -H10.0.10.12  -oSNMPv2-SMI::
enterprises.2378.1.1.2.1.2.80.1.1.3.5 -w 22:60

 54

SNMP OK - 54|SNMP= 54

 

The output from the perl wrapper looks pretty much the same and the
output from plugins that have perf data built in to them so I am at a
loss as to why it doesn't work.

I'm not a not a perl of nagios guru yet, so I figured I would through
this out to the list to see how other folks many have solved this
problem already.

 

Thanks for any guidance you all may provide.
