There are two places which configure logging:
/system logging action and
/system logging. The former is more general and sets destinations of log messages, while the later configure actual logs to be generated (and stored).
By default, there are 4 entries in
/system logging:
[user@router] /system logging> print
Flags: X - disabled, I - invalid, * - default
# TOPICS ACTION PREFIX
0 * info memory
1 * error memory
2 * warning memory
3 * critical echo
There are probably more if you added some logging actions and you should (prior to removing entries in
/system logging action) remove entries with action set to custom actions (see below) by executing commands such as
remove <index> after you executed
print, with
<index> being index number from preceding print command output.
By default, there are 4 entries in
/system logging action:
[user@router] /system logging action> print
Flags: * - default
0 * name="memory" target=memory memory-lines=1000 memory-stop-on-full=no
1 * name="disk" target=disk disk-file-name="flash/log"
disk-lines-per-file=1000 disk-file-count=2 disk-stop-on-full=no
2 * name="echo" target=echo remember=yes
3 * name="remote" target=remote remote=0.0.0.0 remote-port=514
src-address=0.0.0.0 bsd-syslog=no syslog-time-format=bsd-syslog
syslog-facility=daemon syslog-severity=auto
(disk-file-name in rule #1 could be different depending on device type).
With your additions you'll see additional actions and those you can remove (by executing e.g.
remove <index> after you executed
print, with
<index> being index number from preceding print command output).
