I only recently updated to Sierra (10.12.4). Now when I use the Console program to view console messages, I see a massive amount of logging by WebKit, especially about "Current memory footprint":

enter image description here

This makes it very hard to use Console to view messages by any other application. Is there any way to hide specific application messages in the new version of Console? Failing that, is there a way to make Safari stop logging this level of detail, or log them elsewhere?

Select one of those "com.apple.WebKit.WebContent" entries and right-click. There are a few different options to help you hide these verbose WebKit entries. You can filter them out by process name, process ID, category, etc.

Similarly if you want to just focus on the output of one application, you could right-click on one of its entries and select "Show Process 'com.mydomain.myapplication'" to only see entries generated by that application.

  • Ack! I checked for Toolbar items but it didn't occur to me to check if a right-click action might be possible. Now I feel dumb. Anyway, thanks for this – this is perfect.

While the accepted answer probably represents the right thing to do, there’s another way to narrowly answer the question, i.e. how to reduce the logging verbosity of the WebKit subsystem (permanently):

sudo log config --subsystem 'com.apple.WebKit' --mode "level: error"

Now, only error-level messages should be logged. (Caveat: I haven't tested it.)

But I won't recommend this; rather just filter for the messages you need.


Also on the Console app under the Action menu item one can [un]tick the Include Info Messages and Include Debug Messages to change the level of information displayed.
