[keycloak-user] Keycloak 1.8.1 JMeter Performance Test - Login, Refresh Token

[Mustafa Kuru]

Hi,

I am testing Keycloak's Login and Refresh Token with JMeter but getting
errors (~1.50% of responses) by refreshing token.

Login responses are ok.

Path:{server}:8080/auth/realms/customer/protocol/openid-connect/token

The JMeter configuration: 20 Threads, Ramp-Up Period: 5

Responses looks like:

{"error_description":"Client session not active","error":"invalid_grant"}
{"error_description":"Session not active","error":"invalid_grant"}

Keycloak is clustered on the server and has 3 nodes.

Do you have any idea?

Thanks,

Kind regards
Mustafa Kuru
