Per spreadsheet at https://docs.google.com/a/chromium.org/spreadsheets/d/1R_1BAOd3xeVtR0jn6wB5HHJ2K25mIbKp3iIRQKkX38o/edit?usp=sharing , and comment by nednguyen@, we would like

image_decoding.image_decoding_measurement

to be monitored, so alerts are generated for it. I am not very familiar with this perf test but I would imagine we want notifications for:

frame_times, and
mean_frame_time

I believe reveman@ is the owner of this particular test. I would also like to receive notifications if possible.

Thanks!
