Parse one tag value from the tags on the New Relic integration message alert fields

Question

Hi everyone!

I have a New Relic integration in my OpsGenie that works pretty well, with working tags incoming from New Relic. I would like to parse the value of a single tag from my notification channel into the Message field of the integration. Please refer to the screenshots bellow:

How do I parse a single tag value in the yellow highlight above?

For the final solution I used Regular Expressions. This one works well with another tags or with just one:

As seen, I am using the existent cmp_ tags already used for the StatusPage integration.

Works like a charm!
I just have to create a better algorithm because the closing braket ("]") is appearing, as expected. I'll refer to the docs to create a refined parser.

thank you very so much!
