## What?
|
|
|
|
Resuses micrometer from Quarkus distribution to add metrics for Keycloak for events.
|
|
|
|
### User Events
|
|
|
|
User events are added with key `keycloak_event_user_total` and tags:
|
|
|
|
* `type`: [EventType](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/EventType.java#L27) from [Event#type](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/Event.java#L44)
|
|
* `realm`: realm id from [Event#realmId](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/Event.java#L46)
|
|
* `client`: client id from [Event#clientId](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/Event.java#L48)
|
|
* `error`: error from [Event#error](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/Event.java#L56), only present for error types
|

|
|
|
|
Admin events are added with key `keycloak_event_admin_total` and tags:
|
|
|
|
* `realm`: realm id from [AdminEvent#realmId](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/admin/AdminEvent.java#L44)
|
|

|
|
* `resource`: [ResourceType](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/admin/ResourceType.java#L24) from [AdminEvent#resourceType](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/admin/AdminEvent.java#L51)
|
|
* `error`: error from [AdminEvent#error](https://github.com/keycloak/keycloak/blob/main/server-spi-private/src/main/java/org/keycloak/events/admin/AdminEvent.java#L59), only present for error types
