RES: check_rrd modifications

[Marcio Queiroz]

Hi,

i´m using check_rrd_data.pl (contrib directory) to monitor bandwith usage,
and i make a litle script that gives a warning and critical messages in 70%
or 90% of the bandwith. It work´s for what i need. I call that script
check_rrd. If you could send me your when you have finished the
modificatios.

here is the script :

#/sbin/sh

# usage : check_rrd <RRd index in rrd-files> <warning value> <critical
value> <Ds Number : 0 for in/ 1 for out>"

exitstatus=0

saida=`/usr/local/nagios/libexec/check_rrd_data.pl $1 'return "Traffic over
70%: Warning\n" if ($value > '$2');' 'return  "T
raffic over 90%: Critical\n" if ($value > '$3');' 'printf"Traffic Ok - Value
= %.2fKbytes\n", $value; return 0;' $4`
if [ "$saida" = "Traffic over 70%: Warning" ]; then
   exitstatus=1
else if [ "$saida" = "Traffic over 90%: Critical" ]; then
     exitstatus=2
      else if [ "$saida" = "Traffic Ok - Value = nanKbytes" ]; then
              saida="Unknown"
              exitstatus=3
                 else if [ "$saida" = "Can't open data file for $1" ]; then 
                   exitstatus=3
                      fi
           fi
     fi
fi
echo $saida
exit $exitstatus

> The output of check_rrd run from the command line appears like so:
> OK - Current BW In: 1132077 bps
> However, when run from within Nagios the output appears this way:
> OK - Current BW In: bps

> As you can see, the actual data is not passed to the cgi or something.
> This seems odd, because both the 'In' and '1132077' are variables within
> the script, so the first one is displayed and the second is not.

> Any ideas?

> Also, let me know if anyone is interested in the modified script and
> I'll be glad to post it once I get this last bit figured out.
