trex values with curl

Question

I'm looking to use curl to get the metrics from the trex ZMQ server so far I have been trying to do something with curl http://localhost:4500/trex-global -H "Accept: application/json". For this example I would like to get Tx Bw from the output below using curl, the output below is taken from the trex cli
