Here is the link that has the info on the default values for those fields.

That was the link that led me to the right answer.
It told me the two columns mentioned in the question values are not NULLABLE, and always show the value recorded by the system since the last reset.
It also mentioned they are not configurable.
I am certain this is why the two rows in this view have values on my QA 2008 R2 server becuase resource governor has always been disabled on this system.
😎
I read that bit too but considered that statement to be if the system had resource governor enabled. And since those fields default to 0, and resource governor being disabled resets those fields to their default values - I interpreted the question that to equate to Always 0. However, I am leery of any answer that has "Always" in it. I just don't think this question is as straight forward or unambiguous as some may think.
What were the values in your columns (mentioned in the question)?
I've got 0's for the internal group and 38036 and 90888 for the default group. I can enable and disable resource governer as much as I like and the values don't change.
If I then run ALTER RESOURCE GOVERNOR RESET STATISTICS, the values return to 0.

Thanks. That helps alot. I only get one recordset - just the internal group. Excellent learning topic. Thanks all.

Great question, thanks.
I could deduce the correct answer since I ran the query on my development machine.
Not all results were zero and the columns aren't nullable, so there were two options left.
I have never had resource governer enabled, so I chose the 3rd option, which was the correct one.
It was only looking for the results of those two columns though - not all results. The default for those two columns is 0.

OK, I wasn't specific enough 🙂

The values for those two specific columns was 0 for 1 row and 1024-ish-something for a second row.

Thanks for the question, it is nice to know that the RG gathers the stats even when it is disabled.

There is no implication in the question, at least not from what I read, that RG was enabled and disabled. It is "disabled" for non-internal groups by default, and doesn't work in Standard Edition.

In SE, it appears that only one row is returned, the internal group. In that case, I am not sure that it will return anything above zeros, but technically the feature isn't enabled at all.

In DE or EE, it is supposed to return and track the values, regardless of whether or not you have enabled RG for use by the admins to manage pools of connections and limit resources.
