[mrtg] Re: mrtg doesn't work from crontab

[PAUL WILLIAMSON]

How about trying adding a shell to the command and putting the commands
into a shell script?

*/5 * * * * bash /path/to/bash/script

script:

/usr/local/bin/mrtg /usr/home/adam/mrtg/cfg/mrtg.cfg --logging
/var/log/mrtg.log

Just make it executable and add your magic line at the top and you're
all set!

Dear All,

I am having trouble running mrtg with cron and I'd really appreciate
some input.  I'm using mrtg 2.12.2 and perl 5.8.7 It works without
problems from the command line and this is the line I've added to the
crontab:

# MRTG every 5 minutes
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/local/bin/mrtg
/usr/home/adam/mrtg/cfg/mrtg.cfg --logging /var/log/mrtg.log


I've read some other suggestions for fixing this.  I have tried adding
a user to this function call in the crontab; both as a user and root.  I
have tried including a cd/ temp too and of course checking the logs. 
The only real clue is the emails being sent to whoevers inbox it is. 
There are three flavors:
