Expose per-user coding stats as Prometheus metrics

[muety]

If the user, that you're requesting the /metrics endpoint with, is an admin user (is_admin flag on the user object), all metrics, including such prefixed with wakatime_admin_*, should be included.

User that i request is admin! in prometheus i am getting wakatimeadmin*

assume that i have small team! and i want to make dashboard in grafana for metrics -- all spent time for each language for all team -- all user that how many time spent and so on how can i do that in wakapi_admin_* just 4 labels

Per-user coding stats (languages, editors, etc.) are indeed not exposed through the metrics endpoint. You can always only get the ones for the current user, who is doing the request. So currently, you would have to have a separate Prometheus scrape job for every member of your team, including their respective API keys.

I can add this as a feature request, but with low prio, though. So please don't expect me to get to implementing this any time soon.

We won't expose entity-specific data (languages, projects, editors, etc.) as part of Prometheus metrics, because it would blow up cardinality way too much.

Total coding time per user will be included from the next release on.
