Metrics service

/metrics exposes operational metrics of the pantahub-base process itself in Prometheus text format — Go runtime statistics (goroutines, heap, GC), process stats (CPU, memory, file descriptors) and scrape-handler counters. It exists for operators running their own Hub, not for devices or end users.

Point a Prometheus scrape job at it like any other Go service:

scrape_configs:
  - job_name: pantahub-base
    metrics_path: /metrics/
    static_configs:
      - targets: ["base:12365"]

Don't confuse this with the metrics scope of the apps service, which guards user-level metric resources.
