You would have to run the netmon trace and get practiced at reading it.

All of that information is in there but it not available any other way.
 There been many appends on this list about people doing that.

Well james, to clarify a little, a way of checking to see if netmon is
contribution to any performance on the AIX box.  Is netmon falling behing
on polling ?  Is the poll list too long for netmon ?  Is netmon polling too
many nodes ?  how long is the snmp poll list ?  Should I increase/decrease
my polling frequency because netmon is falling behind ?  Just a way of
telling if netmon is performing optimally.

Thanks for any assistance.
