change size of logfile of webserver

[emmi]

hi,
i don't know if this is the right forum.

i want to change the size of the access logfile of the webserver but i didn't find any possibility in plesk to do this. i have can only show, store and delete it.

where can i do this? in plesk or must i change any other configuration of the server?

thanks for your help

best regards
emmi
