There's a very good guide that's attached to every AirWave installation
Check out the "Aruba and AirWave Best Practices Guide"
It's located under Home -> Documentation
There's an appendix that helps differentiate what can be gotten via polls vs traps
The end of Appendix A in particular has a list of traps that AirWave utilizes
Link to most current on support site.
Beyond that, any trap can be tracked using the System -> Triggers -> Device Event or Device IDS Event triggers.
