messages in /var/log/

I have a whole load of entries that look like: 

Aug  3 14:48:38 gandalf -- MARK --
Aug  3 15:08:38 gandalf -- MARK --
...


These are repeated every 20 minutes. How can I determine where are they
coming from and what they mean? 

Thanks,

-K

Second things first ... what they mean is that the system was operational 
at the times associated with the timestamps. If you try to log on to your 
system and find it dead as a doornail, needing a hard reboot, the last MARK 
you find in the logs after a reboot will tell you the approximate time of 
the failure.

As to where they are coming from ... on my Debian systems, it's a built-in 
feature of syslogd. Check your man page for the -m option to see if yours 
matches mine (I haven't seen a question from you in awhile, and I forget 
what distro you are running). You can change the frequency with -m, and 20 
minutes is the default.

syslogd puts it in /var/log/messages, see 'man syslogd'
The -m option is supposed to turn it off, i remember years ago it was not 
possable to turn it off completly, as to it working now i have not tryed.

Hi, K:

Tell us which distribution-release, and kernel version.
On my Slackware-9.1, 2.4.22, it comes from
  /etc/rc.d/rc.syslog
in the line
  /usr/sbin/syslogd
the default 'argument value' is 20 minutes
  -m 20
and can be set to zero (never) with
  -m 0

See 'man syslogd'.

  It may be used to determine, approximately, when a system 'died'.

HTH, Chuck
