I'm posting this to declare aixmonitor inactive. There is a follow-on project (rrdmon) if you are looking for similar features.
1) AIXmonitor is based on source I don't own and the owner was not cooperative.
2) AIXmonitor was working fine on AIX V4, but with AIX V5 some development / fixes would be necessary.
3) I was something working on multiple platforms, at least AIX and Linux, Solaris would be nice too.
Just hop over to http://sourceforge.net/projects/rrdmon/ for the new rrdmon.
