Module metrics 

Prometheus metrics for monitoring calls and server load.

GET metrics::PATH returns 200 OK in Prometheus text exposition format with content type metrics::CONTENT_TYPE. Configure Prometheus to scrape this endpoint. Send PromQL queries to Prometheus, for example:

sum(osfu_users_active)
sum by (stage) (rate(osfu_ws_connections_total[5m]))

metrics::MetricName lists exported names and their meanings. The scrape response includes each metric’s HELP, TYPE and labels.
