Monitor KPIs

I have selected on the Monitor Components one IS service and two broker documents. I called the service several times and published the documents also but no KPI is shown on the monitor pages on MWS.

I am using 7.1.2, but this was also happening on 7.1.1.

I guess something is wrong on my instalation but can figure it. Did some of you ever had a similar problem? Any ideias to fix this (where to look). How to reset everythig and start over?

I also do not quite understood the expression in red.

On InfraDC logs I actualy see these KPI values being collected:
