Thanks for your comments. I've just tried putting a command which produces error output to the same crontab. With the redirection "> /dev/null 2>&1" , I didn't get any email from that cron job. However, mrtg produces mail from error messages.
I am sure that is the specific cron job that mrtg is run, because there is no other crontab of any other user. I don't know why mrtg produces these. I can't track it also, because the error is not occuring at each run. Anyway, I installed Cacti running RRDtool. Maybe I'll pass to Cacti. Thanks.

The OS handles the ooutput of the cronjob - not mrtg. Maybe someone else who uses CentOS can chime in, but some things to try: Like I mentioned before, set up a cron job for every 10 minutes to do a LS / > /dev/null 2>&1 Does that get e-mailed? Are you SURE it's that cronjob? Set up that same job every 10 minutes. Do you get an e-mail every 10 minutes? Do you have other cron jobs that have output to /dev/null ? Do they get e-mailed also? Everything I'm seeing on CentOS says > /dev/null 2>&1 Works. -- View this message in context: http://n2.nabble.com/keep-getting-cron-warning-mails-even...-tp2187838p2199464.html Sent from the MRTG Users Mailinglist mailing list archive at Nabble.com. _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
