Subprocesses don't necessarily count, though:

$ quiz

Quiz> $qtp ...

is one licence.
We watch cognos$license:cognosda.log;* - that shows peak usage.
As far as I know that's the only way to track how much headroom you 
have/haven't got. I've a little DCL procedure that mails peak usage 
monthly or thereabouts.
It's embarrassing to find you've just taken on a bunch of temps for peak 
season, and they can't use the systems because you've not got enough 
licence.
You can also manage your licences - if you've a bunch of screens that 
sit in powerhouse all day, and get used occasionally, there's obviously 
scope for economy by having them exit to DCL between use - the downside 
is it'll take a bit longer when they are used. That technique can also 
be used as an emergency get around if you do get caught short.
