[Dashboard] Replicant Connection Number is Wrongly Displayed about emqx HOT 5 CLOSED

If you don't want clients to have sessions, you may set clean_start = true and Session-Expiry-Interval to 0, when using MQTT protocol v5, or just clean start = true when using older MQTT protocols:

Hi @TxMat .

Do you perhaps mean that you expected "Connections" and "Live Connections" to be the same value? For example, from your screenshots, did you expect the "Connections" field in the dashboard overview to display 5?

Hi,

In a way yes, but I am a bit confused on what to expect because 2 of the core nodes were also connected to the Load Balancer and didn't suffer the same bug (or feature ?). Also the fact that sometimes the "connection" value decrements on a client disconnect and sometimes not is adding to the confusion

from emqx.

"All Connections" in the dashboard include also persistent sessions (i.e., clean start = false), even if the clients are disconnected.

Does "Live Connection" match what you expect?

from emqx.

Oh okay thanks for the clarification, in that case how should I handle disconnection for the client to be "removed" from the persistent session ? I thought that not making a clean start resumes the current session if they were one or creates a new one if none was found.

Yes the live connection value is working as expected.
