A lot of _created metrics provide huge values with Keycloak 18.0.2

[dj-wasabi]

Description

Add a brief and meaningful description.

Several _created metrics provides huge values, which doesn't make any sense.

Expected Behavior

I expect actual representative values that shows how many are created. The values for _created are way higher than the _total metrics.

Actual Behavior

See in steps to reproduce, where I pasted output of metrics.

Environment

• Operating system: Amazon Linux 2
• Project Versions: Keycloak 18.0.2, keycloak-metrics-spi: master

Steps to reproduce

Updated the gradle.properties to:

keycloakVersion=18.0.2
prometheusVersion=0.15.0

Then executed:

./gradlew jar

Copy the jar file to a path that was mounted as /opt/keycloak/providers/ in the Official Keycloak 18.0.2 Docker image. Enabled the metrics-listener event in the realm, added environment variable where to find the pushgateway.

I then get the following when doing a curl on pushgateway metrics endpoint:

keycloak_refresh_tokens_total{client_id="security-admin-console",instance="172.16.2.1",job="keycloak",provider="keycloak",realm="master"} 3

I get a really high value for the items that ends with _created items. This info is shown via "https://FQDN/auth/realms/master/metrics" and via the pushgateway metrics endpoint.

@dj-wasabi did you find any solution ? I am facing the same issue with KC 21 with latest spi 3.0.0.

Hi, no I let it go back then as I believe I was not able to fix it.

Hi!

Just noticed it also. It seems like these values are timestamps!

Those are unix-timestamps in science notation.
