Unique identifier for clients? #519

Closed afrozl closed 8 years ago

afrozl commented 8 years ago

I am using collectd to forward messages to mosca. The client id set by collectd defaults to the hostname or can be manually set. Is there a unique identifier that mosca server assigns to each connection? I need this to ensure that clients don't end up stepping on each other. There is always the possibility that 2 clients/hosts might have the same name...

If each connection has a unique identifier, I can prepend that to the topic to endure that no collisions occur.

If you don't specify an id, Mosca will automatically generate one for you. However, this will be private. Either you generate a unique id on the collectd side, or you allow multiple instances to publish on the same topic.

thanks - I'll create a unique id/identifier on the client.
