1160634 - [Meta] Implement Metrics DOM API for exposure to FxOS

Status: RESOLVED WONTFIX

(Core :: DOM: Core & HTML, defect)

Description

[Tamara Hills [:thills]]

This bug is the meta bug for tracking all the work related to implementing a DOM API which exposes metrics collection capabilities to Gaia.  The API would leverage the existing /toolkit/components/telemetry capabilities to send histograms to the server.

Is there a design doc, or anything similar, for this API? FWIW, I've talked about something similar with a few Chrome folks in the past and I'd like to understand what you guys are thinking: shape of API, functionality, overlap (or not) with other perf-measurements APIs, etc.

Hi Ilya,

We don't have a formalized design document as of yet.  We are still in process of figuring out what metrics are already collected in gecko that we can leverage.  We may choose to focus on this set first due to time constraints.  There will be some set of the metrics that will need to be triggered from Gaia.  One example of this is something like an app startup time.  The initial list of what is requested for us to deliver is here:  https://wiki.mozilla.org/Gaia/Metrics#Phase_1_Requirements_for_Architecture_Validations

Thanks,

I'm actually more interested in the API itself, not the metrics: "... DOM API which exposes metrics collection capabilities to Gaia. The API would leverage the existing /toolkit/components/telemetry capabilities to send histograms to the server."

I'd like to understand how this is different from User Timing, and how you guys are planning to handle histograms, etc.

I don't think we are going to work on this anymore. Closing.
