You're going to have to provide more information.
It looks like you're already connected with Ignition, but if you're using SparkplugB, it's not as easy to just eavesdrop and monitor the data going back and forth. SparkplugB does make it easy to get your tags as it automatically will bring in tags as they're published from the edge (MQTT Transmission). If you're using plain MQTT topics without SparkplugB, you'll have to do a custom namespace, which I've never done personally, but there should be documentation on how to do this on Cirrus Link's website.
