Can you clarify which metrics you'd like monitored? Other smoothness tests are generally monitoring some combination of:

input_event_latency_discrepency
mean_input_event_latency
frame_times
mean_frame_time
first_gesture_scroll_update_latency
touch_scroll_latency_discrepency

Sorry about that. We'd like monitored:
frame_times
mean_frame_time

Thanks.

Ken: there is also frame_times_discrepancy, which is the best metrics that reflect jank according to Manfred

That sounds good too, thanks.

Added monitoring.
