Debuggin Check-Scripts

[Thomas Guettler]

Hi,

I had difficulties to debug the check commands.
I wrote a little wrapper script, which logs some
informtion into a logfile. The is usefull if you want
to see how variables (e.g. $USER1$) get expanded and
which command is actually run.

Use it like this. You need absolute path $USER$ gets only
expanded once!

command_line    /usr/local/nagios/libexec/log_checkcommand $USER1$/check_...

Here is the script:

#!/bin/bash
SCRIPT=`basename $0`
LOGFILE=/usr/local/nagios/var/checkcommands.log
if [ ! -w $LOGFILE ]; then
   echo "$SCRIPT: Can not write to $LOGFILE"
   exit 3
fi
echo `date` >> $LOGFILE
echo `id`   >> $LOGFILE
echo $@     >> $LOGFILE

for arg in ${1+"$@"}; do
    echo "arg $arg" >> $LOGFILE
done
echo       >> $LOGFILE
${1+"$@"}
