Official Prometheus Exporter Plugin for Discourse

The Discourse Prometheus plugin collects key metrics from Discourse and exposes them in the /metrics path so prometheus can consume them.

Adding custom global collectors

The global reporter can pick custom metrics added by other Discourse plugins. The metric needs to define a collect method, and the name, labels, description, value, and type attributes. See an example here.
