[mrtg] Re: crontab & MRTG emails

[Peter Wirdemo (MO/EMW)]

I always use a wrapper script for mrtg...

#!/bin/sh

LOG=/var/tmp/mrtg.out.$$
rm -f ${LOG}

/usr/bin/mrtg /etc/mrtg/mrtg.cfg > ${LOG} 2>&1

if [ -s ${LOG} ]; then
        cat ${LOG} | mail -s "MRTG Report"  someone at domain.com
fi

rm -f ${LOG}

And then in cron....
0,5,10,15,20,25,30,35,40,45,50,55 * * * * wrapper.sh > /dev/null 2>&1
