The undefined nice cpu metric is reported as zero. Only linux reports the disk data, I believe, which is why you won't see it on AIX. (The info is most likely there, I just haven't written in support for it, and nobody else cares enough to submit a patch. :) Conversely, AIX has the cpu io wait metric, which other platforms don't. Unfortunately, ganglia 2.x doesn't have a good way to deal with different platforms having some metrics and others not. I believe the in-development 3.0 version will have sane ways to deal with heterogeneous clusters. Check the archives of this and the developers list for the problems that have popped up with this. -- Preston Smith <[EMAIL PROTECTED]> UNIX Analyst Purdue University Physics Computer Network GPG Fingerprint: 6D27 5DAA F58D C42B 7A6B 8F48 04E4 2465 F353 03F6
