Monitoring with Prometheus+Grafana

Description

Hi,
I’m new to RocketChat and I have a few questions.
I configure monitoring on two instances but in the Grafana can see only one on the “Users Online” panel. How to can I see metrics from the second instance in Dashboard?

P.S.What is “DDP users”?

Thanks!
