Nagios and performance data

[Frederik Vanhee]

Hello,

I'm doing some experiments with performance data, but experience some 
strange behaviour
I have a plugin 'check_iftraffic.pl' that returns this :

Total RX Bytes : 145.74 MB, Total TX Bytes: 242,75 MB, Average Traffic: 
2,89 kB/s (0,0%) in, 6,25 kB/s (0,0%) out | inUsage=0.0,85,98 
outUsage=0.0,85,98

In nagios.cfg, I put 'process_performance_data=1'
So I expect that Nagios splits the plugin output in two Macros :
The text before the | should be the service output and the text after 
the | should be recognized as performance data

$SERVICEOUTPUT$=Total RX Bytes : 145.74 MB, Total TX Bytes: 242,75 MB, 
Average Traffic: 2,89 kB/s (0,0%) in, 6,25 kB/s (0,0%) out
$SERVICEPERFDATA$=inUsage=0.0,85,98 outUsage=0.0,85,98

Instead of what I expect, Nagios drops the text before the | and the 
text after the | is treated as the plugin output, so in my status-cgi's, 
I get :

inUsage=0.0,85,98 outUsage=0.0,85,98

and I don't get any performance data.

I thought it had something to do with an illegal character, this is what 
I have in nagios.cfg :
illegal_macro_output_chars=`~$&|'"<>


Any hints ?
Apart from perfparse, what programs are you using to interpret 
performance data ?

Thanks,
Frederik
