I have deployed redmine over kubernetes and a monitoring stack consisting prometheus, grafana and alertmanager. I have to perform application monitoring through prometheus for which I need to expose the metrics of redmine. There is only one plugin available for this named 'redexporter': https://www.redmine.org/plugins/redexporter

I have successfully installed it but it is not working. Maybe the problem is due to the compatibility issues since this plugin is compatible with 3.x.x but the official images present over docker hub include only 4.x.x versions.. I am not able to think of any other alternative to this.. The only thing I want to do is expose the metrics of redmine to prometheus.. So, what should I do now ??
