Hi @ferdisn, yes I spot this issue while doing my example.
I started a thread about it on the mailing list: Look for "Metrics Gauge
Example and Bug".
Send your PR there and ask questions on how to fix it. This is a great
example of bug you can fix.
I checked the TCK yesterday and I was trying to find the solution for this
as well.
It seems to be a problem with the jsob provider. ---
