A Prometheus exporter for NATS metrics, exposing server monitoring information including connections, subscriptions, routes, and JetStream statistics.
Prometheus NATS Exporter is a Prometheus exporter for NATS server metrics. It collects monitoring information from NATS server endpoints and exposes them at an HTTP endpoint that Prometheus can scrape.
The exporter aggregates metrics from various NATS monitoring endpoints including varz (general server info), connz (connections), subz (subscriptions), routez (routes), healthz (health status), and JetStream statistics. This enables comprehensive monitoring of NATS infrastructure in Prometheus-based observability stacks.
