Re: [keycloak-dev] NPE in keycloak logs in MetricsEventListener
Hi David, Hi Jose,
we’ve also seen this today when debugging Keycloak with Jose. Looks like we need to add
null checks to
https://github.com/aerogear/keycloak-metrics-spi/blob/mobile-metrics/src/...
<https://github.com/aerogear/keycloak-metrics-spi/blob/mobile-metrics/src/...
and
https://github.com/aerogear/keycloak-metrics-spi/blob/mobile-metrics/src/...
<https://github.com/aerogear/keycloak-metrics-spi/blob/mobile-metrics/src/...
Jose found another issue: For the metrics to work we need to add the metrics-listener to
every Realm we are interested in (metrics wise). That happens automatically for the
Project realm. But if the user creates a new Realm in Keycloak or through a custom config
file then this listener is not added. To enable metrics the user would have to add the
listener manually in the Keycloak Admin Panel.
@David: do you think this is an issue? It means additional config steps for custom Realms
that need to be documented.
I think it’s possible to add the metrics-listener to every realm automatically by
configuring it in standalone.xml:
http://www.keycloak.org/docs/3.3/server_installation/topics/config-subsys...
<http://www.keycloak.org/docs/3.3/server_installation/topics/config-subsys...
Especially by running a CLI command to add a SPI to the config:
http://www.keycloak.org/docs/3.3/server_installation/topics/config-subsys...
<http://www.keycloak.org/docs/3.3/server_installation/topics/config-subsys...
Will look into this with Jose.
Regards,
Peter

@Jose, @Peter,
sharing this on the lists in case anyone else comes across it (I came
across it while chatting with Jose on IRC).
I also see successful events being logged in keycloak and getting
through to prometheus & the grafana dashboard.
