Menu: Filter -> Filter LogLevel
Filter Loglevel is a submenu of the Filter menu containing an item for each of the four Loglevels: Info, Error, Warning and Alarm.
These submenu items fully correspond to the Loglevel buttons on the Loglevel filter toolbar. So they work as toggles to activate or deactivate filtering for this Loglevel.
We recommend using the Loglevel filter toolbar instead of this submenu.
