I don't believe we want -1 or 1-.

I believe the below regex is what we're looking for.
(You'll be able to accept my suggestion by clicking "commit suggestion".)

Suggested change

	^\s+[-\d]+\s+frame
	^\s+(-|\d+)\s+frame

Based on my example on your other PR #1964, please include test data for this PR.

The required test data should include:

• raw cli output (remove/sanitize sensitive info)
• and generate structured YAML data with helper scripts

Information about setting up your development environment.

Edit: You'll also want to rebase your patch-1 branch off of the current state of the NTC master branch. It's not all that difficult, but it is a small hurdle. The reason to do this is to make sure there aren't any merge conflicts (and if there are conflicts you can resolve them early).
