In the http.log module is the keyword exceptonly for paths is there another possibility do not log this line or should I open a RFE (=Request for enhancement) to add such a feature?
Yeah, sounds like a candidate for a feature request on the Github repo.
I don’t know how much traction it will get, though - just about every log viewing tool in existence has very simple methods to exclude arbitrary lines from its output (e.g. grep -v "Pingdom.com_bot"), and it can be stripped out after the fact equally as easily, so there’s not much need to exclude this data at the collection stage.
