Statistics Center

The Statistics Center provides detailed numbers beyond the Overview KPIs. It has two tabs.

System tab

Point-in-time infrastructure metrics:

  • Go runtime — uptime, goroutines, heap, GC cycles and pause.
  • PostgreSQL — server connections, application pool state, transaction totals, buffer hit ratio, deadlocks.
  • NATS — messages and bytes in both directions, client reconnects.
  • JetStream streams — stored messages, sequence ranges and per-consumer backlog (pending, redelivered, ack floor).
  • MQTT broker — type and number of connected clients.

Business tab

Tenant-wide activity for a chosen time range (last 1 hour, 24 hours or 7 days):

  • Fleet totals and devices by profile.
  • Telemetry volume timeline.
  • Alarms by state and severity; commands by current state.
  • Count of active rule chains.

Refresh

Both tabs refresh automatically every 30 seconds. Use the pause button to stop auto-refresh, or the reload button to refresh immediately.

For monitoring systems

The same metrics are exposed in Prometheus format at /metrics. Point Prometheus at that endpoint and import the Grafana dashboard from deploy/monitoring/.
