Disable log output to tty1

[The_Raven]

Maybe a "stupid" question, but how can i disable the log output to tty1?

The log is filling my screen with "spam"

Do you mean kernel messages?

setterm --msg off

Perfect, it looks like it's that! 

LOL, i googled and duckduckgoed around the world, found a lot of "stupid things" like change config files and such things, but at the end it is so easy... 
Thank you very much!
