问题
Chrome developer tools has an option to Start/Stop Recording profiling data with respect to Memory,Paint,Screenshots,JS Profile on the Timeline tab. Once I refresh a page the recording begins automatically and stops when the page has loaded.
Is there a way to
1)Start this recording in the background automatically without needing to open developer tools in chrome/node-webkit window. Maybe the recording can be enabled via some Chrome API which can be called when the application loads
2)Dump the recorded data into a log file (e.x. a json file) once the recording is over.
Any pointers in the right direction will be appreciated.
