Is there a way to know how many Apps users are logged on at a specific time?

I suppose we can do "ps -ef | grep LOCAL=NO". Would that give accurate information? How do I get a total of those?

Is there any way to query database tables to get this info?

Something like Top Sessions in OEM?

Spotlight on Oracle from Quest has # of users on its screen.

We are on Apps 11.0.3.

Anything else? Thanks.
