MQTT problems

I'm running TW 7.2.0-b155 on AWS, which was installed for me by Thingworx.

I'm attempting get data from MQTT into Thingworx.  I verified that the data is reaching my broker and can be subscribed to. However the data is not showing up in Thingworx.

I've checked that the topic names match in all places.

For one of my things, lastConnection is "2017-08-28 11:10:33.833", isConnected is false and lastUpdated (set to the eventTime) is really old.

1) How can I tell if Thingworx is connected to the broker?

2) How can I tell if Thingworx is receiving messages?

Is there a log setting in the Monitor that would allow me to see that information?

Thanks for the help,

Dan

Hi, Dan.

I don't know if you've seen this article, but maybe it will help guide you.

Re: MQTT problems

No..these connections were working and stopped last week with no known config changes to Thingworx.

Does Thingworx log when it opens a connection with an MQTT Broker? And if so, where can I find that information?

Hi Dan,

Did you check the CommunicationLog? It may give you some hint.

Re: MQTT problems

The comms log is set to debug and it is quite literally empty.
