Management console

The broker embeds a FluentUI console on the admin listener (admin.addr, default :8081, plain HTTP). Sign in with the admin operator credentials.

Panels:

  • Overview — connection count and message counters (also on $SYS/#).
  • Sessions — active and stored (offline) sessions; disconnect a session, or forget its persistent state.
  • Topics — a bounded recent-traffic view (at most ~1000 topics, 256 payload bytes each, idle entries dropped after ~30 minutes), not the full live subscription tree.
  • Clients — the builtin MQTT credentials and their ACL rules (create / edit / delete), plus blocked and rejected clients.
  • Users — the admin-panel operator accounts (who can log into this console) — separate from MQTT clients, no MQTT ACL.
  • Auth — the active provider chain and the anonymous-access toggle.
  • Test client — a browser MQTT client (over WebSocket) that connects to this broker to publish and subscribe live.

Backed by the Admin REST API.
