Connected Clients view in the Coreflux HUB showing two active MQTT v4 connections with an empty detail panel
Why View Connected Clients?
You need to know which clients are connected to your broker—devices, applications, or the Coreflux HUB itself. The Connected Clients view shows all active MQTT connections with detailed connection info, traffic statistics, session data, and last activity so you can verify connectivity and troubleshoot disconnections.When to Use It
- Verifying device connections — Confirm that sensors or gateways are connected
- Troubleshooting — Check if a client has disconnected or failed to connect
- Monitoring — See how many clients are using the broker and their traffic
- Debugging — Inspect session state, pending messages, and last activity timestamps
