MQTT Client Monitoring

View live MQTT client data, search for and delete unconnected MQTT clients.

You can use the MQTT client monitor to delete inactive MQTT clients. You can view metrics on the following information for MQTT clients that are disconnected, durable subscribers:

• Client ID

  The client ID is the identifier that is associated with an MQTT client.

• Last Connection Date

  The most recent date that the specified client ID connected to Eclipse Amlen.

If a client is not connected to Eclipse Amlen for a significant time, then you might want to consider deleting that client. For example, consider deleting a client if a device is lost, or damaged. When you delete a client, you also delete any durable subscriptions (and associated buffered messages) created by that client. Alternatively, there might be an error that is preventing that client ID from connecting.
