Thanks for the contribution @jermarchand , this looks reasonable to me
@jermarchand this works as long as users are created or register through the UI. When using the API to create users (like e.g. the keycloak operator does) no register or create event is fired and the users are not counted. One solution would be to count the users on every regular and admin event. Not sure if this could lead to excessive database queries when scraping metrics often?
I don't know how operator work :/ If it use the "Registration flow" a user event "Register" is generated. If it use the Keycloak Admin REST API an admin event "CREATE USER" is generated.
Motivation
Add a new metric which is a gauge of the total number of users on the Keycloak instance. https://github.com/aerogear/keycloak-metrics-spi/issues/81
What
Add 1 Gauge :
Why
Show the number of users
How
On REGISTER or CREATE/DELETE User events, count the users of the realm.
Verification Steps
Add the steps required to check this change. Following an example.

Progress
Additional Notes
I'm a newby with Prometheus metrics, so fell free to comment and propose better implementation.
Until first REGISTER or CREATE/DELETE User events, the metric is not set.
