      In Keycloak, turn the KEYCLOAK_STATISTICS flag to true. Open  http://localhost:9990/metrics  endpoint. See that some metrics are duplicated.

      We are using Keycloak which generates metrics using the jBoss CLI: https://github.com/keycloak/keycloak-containers/blob/master/server/tools/statistics.sh

       We want to use Telegraf (with the Prometheus input plugin) to read the generated metrics. However, we get the following error:

      Error in plugin: error reading metrics for http://localhost:9990/metrics: reading text format failed: text format parsing error in line 34: second HELP line for metric name "base_gc_total"

      The base_gc_total metric appears twice for some reason. See the full metrics output in the attachment.
