i'm doing that kind of setup. each of my lpars (about 30 so far)
has a daily cronjob that fires nmon and collects data every 5 minutes.
then another server, where Nmon graphs are generated, has cronjob
running a script to:
1. scp for the remote nmon outputfiles at an hourly basis
2. delete the current day nmon graphs
3. generate graphs from the scp'd output files
the nmon script i'm using is also updating a long term report that
can show the last 4 weeks of utilization for each lpar.
you can get a lot of info from this site:

the later releses of nmon and nmon2web scripts have a different
approach but i haven't tried them out yet.
