Scan mode?

[aptonline]

Is there a chance to add a scan mode (similar to how Mqtt.fx does it) where is would show you all available topics from the MQTT server?

For posterity, I'll repeat my opinion:

@apt brokers can carry millions of topics. I would not want that feature or my iOS would go ‘boom!’

But maybe I'm just too conservative. :-)

I am not sure what you mean.

MQTTInspector already collects all topics received, but it limits it to the last 256 topics received.
It also collects the last 512 PUBLISH messages received and the last 1024 low level MQTT commands.

This means when you subscribe to # on m2m.eclipse.org, it will overwrite the list as there are currently about 4500 topics on that broker (retained and published). The number may obviously change any time.

I am not sure if I want to make the size of the collections configurable...

@jpmens strangely I didn’t see your additional tweet until now. Was posting here as your original tweet ‘not to my knowledge’ made me thing I should investigate further.

I was asking the question as I haven’t purchased MQTT inspector yet and it’s really the main reason I would want to purchase it.

From your answers it sounds like it does do what I want so I’ll take the plunge.

To confirm I want to be able to list the available topics on a server (like MQTT.fx does with there scan feature).
