Output Metrics not working ?

Hello.

I'm trying to figure how to use the Output Metrics. I've searched the forum but can't find much. The wiki says nothing about this component :( No example in the samples folder. So here I am.

I've tried different thing but nothing works.

1st test: Table Input -> Flat File -> Output step Metrics
In the output metrics, can't see any step in there.

2nd test: Table Input -> Flat File with a standalone Output step Metrics (guessing that I might not have to attach it to anything),
Still can't see any step.

In both tests, I select the "Get step" button an nothing is returned. If I select the dropdown, nothing.

I'm using version 5.0.1-Stable on Windows 64 bits if that might help. What is it that I'm not doing correctly?

Thanks.
