If you find that your workstation's /var/log/messages file is cluttered with every-10-minute cron entries like these:
Feb 21 07:00:01 oilslick cron[19045]: (root) CMD (test -x /usr/sbin/run-crons && /usr/sbin/run-crons ) Feb 21 07:10:01 oilslick cron[19097]: (root) CMD (test -x /usr/sbin/run-crons && /usr/sbin/run-crons ) Feb 21 07:20:01 oilslick cron[19149]: (root) CMD (test -x /usr/sbin/run-crons && /usr/sbin/run-crons )
And, if you want to drop these (for the sake of clarity in your /var/log/messages, one way is to filter out all cron-related messages, by adding the bolded/red lines. Think twice, though, if this is really, really what you want to do :-O It may be better to continue to log, but just to a separate file which you can review when/as needed
destination messages { file("/var/log/messages"); }; # We will take out the annoying cron notifications filter nocron { not facility(cron); }; # We will also remove the annoying spamd notifications filter nospamd { not program(spamd); };
# By default messages are logged to tty12... destination console_all { file("/dev/tty12"); }; # ...if you intend to use /dev/console for programs like xconsole # you can comment out the destination line above that references /dev/tty12 # and uncomment the line below. #destination console_all { file("/dev/console"); }; log { source(src); filter(nocron); filter(nospamd); destination(messages); }; log { source(src); destination(console_all); };
