Hey @rgordill,

Thanks for your contribution. I see some test scripts failing, mainly because of metric name usage in thresholds. Please update those as well.

@rgordill Thanks for the fix.
Would you please fix the formatting of the script files with prettier? I'll fix that.

Thanks for your contribution!
