Broker $SYS topic

[Navorski]

I wrote a handler when a client connects to the server, i would like the server to send some system information to the client

$SYS/version
$SYS/uptime
$SYS/clients/active = x
...

But how can i send this information to the newly connected client alone? since all the other connected clients don't need an update.

Or what would be the correct way to handle this?

• don't use MQTT for this, as the "brokering" isn't needed
• use a client-unique topic for this -- i.e. the client sends a Guid with the connect, then the server publishes and the special topic (that uses that Guid as part of the topic) the desired info

I understand but i got the idea because of a common Mosquitto server, such a server is also doing that.
