Telemetry

We are brainstorming what would be the useful information to collect. Please help with your wisdom too!

1. Page views and how long people keep the page open. For example, the events/telemetry page may not be the most visited page, but users can have it open and running for a long period of time.
2. The very error that caused the app to crash (the error stack preserved in ErrorBoundary)
3. Service calls and it's status code returned. If necessary, we can also add request body and response. We shall prioritize the work based on the issues being filed. For example, the very first API call we make is 'get devices' where most users would have trouble getting the first call to work if users' environment is being blocked.
4. We are interested to the know how many users proactively click the 'update to newer version of the app'.
5. Issues being reported where telemetry could help should be prioritized.
