Does WPM has the capabilities to gather details like google analytics?
I am going to say probably not, but it depends on what you're actually looking for with metrics. Google Analytics, as I understand it, helps you determine things like ROI for your various elements your pages by tracking where people click, what lead users to continue using the site versus leaving the site, things like that. Web Performance Monitor does not do these things, its main focus is to record steps a person takes to, for example, login to a webpage and makes sure that an image is loading correctly. Its main job is to tell you when your website is slow, and where within the TCP stack slowness may be occurring. There is no focus on user traffic in and of itself, but if the webpage is 100% available to any potential users and if not, why.
Hope that helps!
