How to view current users with Performance Monitor?

Tinkering with Performance Monitor, I see:

• Web Service -> Current Connections
• Web Service -> Get Requests/sec

Are there better counters to look at? Or perhaps other software?

Thanks, -E

• As you can see in the image below, using Web Services -> Get Requests/sec is mostly sufficent for my needs. But, I was hoping on something more elaborate.

  But considering how this is free, can't beat free.
