trouble exposing metrics in a wildfly domain

[Giulio Gentile]

Hello everyone,
i hope you can help me, i've been trying to figure out how to get to export metrics,
i have a topology with two hosts X two server groups, so domain mode with 4 servers.

i can see status statistics and datasources in the management interface, but i need a way to expose them so i can bring them to Prometheus.

It might be simple, but i'm a little lost.

i tried using prometheus jmx exporter, but it clashes with wildfly logger and the server won't start.

Does micrometer work in this situation?
Is there an existing API i can use?

thank you,
Giulio

There should be a /metrics endpoint on the management port iirc.
Not sure how it is done in domain mode though.

If I recall correctly, metrics doesn’t work in domain mode, as it needs a context on the management interface, which is not available in domain.
