Basically BMC and NMON do the same thing. However as BMC professes to be Platform Agnostic it is not as useful as NMON for tracking down performance problems. BMC also doesn't seem to understand the consequencies of Dynamic LPARing.
I'll be honest, that most AIX locations I've seem - whether or not there is end to end monitoring by BMC Patrol or something else, the local sys admins maintain an NMON trace of the system as well anyway, as they eitehr don't have the access to BMC data when they need it - or else they don't understand it.
Also Memory Managemen Monitoring on an AIX box is always interesting as Memory is allowed to fill up on AIX and is therefore almost always 100% full. Only tools that can Monitor the vmstats can actually see what the memory is doing.
