How to capture Android Web Browser performance metrics?

I have an ask for capturing performance metrics from a mobile web browser called Silk.

My device is an Android device so I can ADB to it. Is there a way I can capture a performance metrics from an Logcat or any type of logs?

The types of performance metrics I am trying to capture are like: Frame Drops, Latency, Time To First Frame, Error Rate etc...

An example scenario is like this: Go to website X, then navigate to page Y and capture the latency, time it took to render the frame.

Another example is: While on the web page, scroll Up/Down and capture the frame drops, time it took for scrolling etc...
