Meta bug of sorts. We need to make sure any client code gets landed in understand success of Push and Notifications project.

NI: product - we need to figure out what questions we want to ask from Push Notification ASAP - if we need to land code for Fx42 or Fx43.

Will set up a meeting with :wmaggs to address this.

Key KPIs for 44: % of users who see a permissions prompt that grant permission (good to know in general, but useless unless we have at least some per site. % of notifications that are seen by a user that are interacted with

Ian sent email on this a while ago: - Number of Push API subscription requests that fail in the client (server offline, client offline, something else happens) - Denominator: number of Push API subscription requests total - Number of Push messages that fail with an error (an exception or timeout in the service worker, or the service worker being killed before completion) - Denominator: number of Push messages - Stats around the permission dialogs (click throughs, rejections, maybe neither accepting nor denying but navigating away). Maybe this already exists. - How often people tweak the permissions later, and to what end - Stats around popup notifications. - Number of popups - How often people click any of the different parts of the popup (what parts there are depends on the result of UX) - There might be something about how the popup onclick is implemented. Does it fail back to the default action? Does it open a new page? Focus an existing page? Apparently do nothing? This one might be a little harder, as it's action at a distance.

I think the KPI of the feature is: primary: * percent users who disable the feature completely over time - this value is the ultimate signal that I don't like this feature. secondary: * percent of sites blocked vs total sites that prompted permission dialog over time - if the percent is high, their general perception and experience of the feature is negative. we could also A/B test different display duration times against the secondary KPI.

I think we will get a lot of these metrics from bug 1207089 and then we can add push-specific ones on top.

We should add Do Not Disturb probes too

Kit and I discussed the probes and clarified some in https://public.etherpad-mozilla.org/p/notification-telemetry

I think we can close this out and file follow-up bugs for any additional probes that we may need.
