Today I was in a requirement to clear the Mikrotik LOG window and clear all the commands from the Terminal console history dueto some security and privacy reason. Since I couldn’t found a simple command base method to clear LOG window, I followed a workaround and it worked like a charm.

CLEAR Mikrotik LOG WINDOW HISTORY [Jz]
/system logging action set memory memory-lines=1
It will delete all previous entries.
/system logging action set memory memory-lines=100
It will change it back to the default number of lines. or let it set to 1 , if you dont want any info, which is not recommended in any case 🙂
CLEAR Mikrotik TERMINAL CONSOLE HISTORY [Jz]
In newer version of mikrotik 6.x, you can clear console commands by using
console clear-history
Note: Sticking with newer firmware (but surely stable one) is always a Good idea so that you stay safe and secure with lots of new features 🙂
However I really wish that Mikrotik can add an “CLEAR ALL LOGS” button in the future 😉

,
I have this error displaying on log window “Running out of disk space, when minimum 500kb is reached UM will be stopped!” Can’t figure out how to turn it off or fix it. Googled everywhere, didn’t find anything. Will appreciate if anyone could hint how to disable it or fix it.
