Hi all,

I'm a new one Mosquitto. I want to know how many connections are connecting to Mosquitto server? I'm recommended using this command($SYS/broker/clients/active), but I don't know how to configure to execute it, Currently my mosquitto is running at default model.

Everyone please tell me know. thanks for any help.

Regards,

Phuc

Hi Phuc,

$SYS/broker/clients/active is a topic on the broker that you can subscribe to using an mqtt client. The client will then receive the messages published to this system topic by the broker.
