Hi,
I am looking at using mosquitto for some project. I wanted to understand
one thing. Is it possible to subscribe to some topic which can give
information about the list of current topic subscriptions in the broker? I am
looking at a use case wherein I would have a publisher publish a message
for a topic only if there are subscribers for that topic. I understand that
the publisher and subscriber should be independent, but just wanted to
check if this is possible

Hello,

I would like to join in for this question, because I have the same issue. In my application though, I am using a webapp as an interface between the user and the MQTT server and its clients. Because the clients change dynamicaly I need a command to get all the subscribed topics on the broker so the webapp can provide them as "options" to the user.

Thank you all in advance for your help.

Kind regards

Simon
