FR: Counters

[akauppi]

Use case:

One wants to monitor some events, or incrementing amounts (see later), on a central way.

• increments can be any float (defaults to 1)
• increments can have tags (eg. for a visitor count, the country, browser type and client language).

Considered:

• Firebase Events needs Google Analytics to be enabled; don’t want to force that..
• Plausible Analytics has goals, but they a) seem to be increment-by-1 only, b) don’t have so nice graphs output as Sentry dashboard (percentiles; tag distribution)
• Sentry…. TBD. What was the reason not to??

Implementation:

The counts would be sent with eventual consistency. Cloud Functions writes the data to eg. Firestore (see notes, later).

There’s a local dashboard in the project that reads from such (online) storage and presents the graphs to the developer.

Notes:

• The local dashboard feel a good approach. No need for an online admin tool. (Why do people even make those???)
• Use of Firestore is not ideal (yeah, I know) but most familiar. Backend can be changed, later, since it doesn’t affect the web app.

Estimation:

• Storing counters by Jun 2022 milestone
• Admin UI by Sep 2022 milestone

Storing counters done (next.jun22 branch)

For Sep stone:

• [. ] study use of Graphana (within DC) for visualization and configuration
