No .log files. Something happened, either at 06:15 or between 06:15 and 06:20.

1: next time, show "date; ls -la". This adds current local time, and last directory change.
2: look at "df", perhaps you have disk full
3: look at your mail. Errors and warnings should arrive there. No, "mrtg >/dev/null 2>&1" in your crontab is not a good idea.


Here is the output of date; ls -la:

[r...@missioncontrol mrtg]# date; ls -al

Disk drive isn't full:
[r...@missioncontrol mrtg]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              19G   15G  3.4G  82% /
none                  124M   12K  124M   1% /dev/shm
/dev/sdb1              19G   18G  374M  98% /mnt/hdb1

I had emailing to root disabled, my ISP blocks outbount port 25 so I couldn't have it email this address. I've changed it to mail localhost, so I'll let it run for a bit and see what happens. I also changed the cron to add logging:

0-59/5 * * * * root env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --logging /var/log/mrtg.log
