To be clear, you're saying that you're not getting any endpoints from the "monitoring" namespace?

[Misterhex]

@brian-brazil yes. no endpoints from monitoring, same configuration work for 2.2.1 but did not work in 2.3.1.

[brancz]

@Misterhex could you share the whole config as well as the logs of the instance?

[simonpasquier]

I've got a fix, just need to write some tests.
