Is Chrome running in a container? NO
Snippet of code to obtain timeline information
rawEvents = []
Tracing.dataCollected(function(data){
var events = data.value;
rawEvents = rawEvents.concat(events);
});
Page.loadEventFired(function(){Tracing.end()});
Tracing.start(); Page.navigate({'url': 'http://github.com'});
When I dump the contents of rawEvents in a file and load inside chrome’s performance tab using the graphical interface, it gives an empty timeline.

I didn’t thoroughly check the output, I just noticed that something has been loaded.
Anyway, if you inspect DevTools during the tracing you can see that it’s using something like this:
Maybe you could try playing with the
categories
param (not sure if it defaults to “everything”). I’m shooting in the dark here…Perfect, that seems to work. Thanks a lot!
I don’t know why the dev protocol says the ‘categories’ option is deprecated since not using that doesn’t work with the latest version of Chrome. I would leave it up to you guys if the dev protocol should be updated, or the example provided as a part of this repo.
I’ll be closing this issue.
