That's actually a big topic.  My favorite tools include:

- ORCA
- dim_STAT
- vmstat / mpstat / iostat / sar / prstat / pmap

The hard part is taking an environment that 's already in use and trying to divine out what the max limits are on it.  Production level system have lots of valleys and peak in their performance curves.   You can do capacity planning on this systems but it takes longer and is prone to more error generally.  The better way is to build a test env and beat it up - 99% of folks I've worked with just glare at me real ugly when I say this.

You might want to consider a training class:

I've taken classes from this guy.  Very good - maybe a little too deep at times though.

You might also want to consider a Capacity Planning book like this one:

Here are some older Sun Blueprint document on capacity planning and performance management:

You should see what Adrian Cockroft has on his blog site (actually I do too - I haven't read it in a while)

You might want to check out his book too.  Its rather old but the concept are still very relevant.
