Unable to log Timeline events

[Ido Abelman]

Using ChromeDriver from Selenium on Python

When I enable performance logging  (setting 'goog:loggingPrefs' on the DesiredCapabiities object to {'performance': 'ALL'}) it is my understanding that by default Network, Page and Timeline events should be logged - however I only see Page and Network events.

If I try to enable Timeline events using something like this:

chrome_options.add_experimental_option('perfLoggingPrefs', {

            'enableNetwork' : True,

            'enablePage' : True,

            "enableTimeline": True

            })

I get this:

selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: cannot parse capability: goog:chromeOptions

from invalid argument: cannot parse perfLoggingPrefs

from invalid argument: unrecognized performance logging option: enableTimeline

Any ideas?

Looking into it a little more I realized Timeline is deprecated. This is a proposed fix that I found: https://github.com/cabbiepete/browser-perf/commit/046f65f02db418c17ec2d59c43abcc0de642a60f'

However when I use this I don't seem to get events for my JS function calls which is what I'm looking for. Any idea?
