Dear Team,
I am planning to implement monitoring using Prometheus and Grafana. To do this, I am adding the necessary JARs and WAR file to Artemis version 2.33. taking these files and building the project using Maven, I followed the steps from the provided GitHub URL. However, upon starting Artemis, I am encountering the following error in the console. https://github.com/rh-messaging/artemis-prometheus-metrics-plugin Error Hawtio loginRedirectFilter is using 1800 sec.
