rstatd returns certain information about the system when queried via RPC calls. Perfmeter (on Suns) displays ten parameters (cpu, disk, swap, context, etc.) rstatd, however, returns four values for CPU and four for disk, which are wildly different. Anybody know what each of these values means, and how to scale the values returned to a fixed scale? I'm trying to write (extend) a Java applet I wrote so that it can be used as a quick reference to system performance, and I don't know how to deal with these values.

<URL:http://www.hesketh.com/schampeo/Faces/> is the previous Java applet, if anyone wants to check it out. The idea is that a face will be more easily and more quickly recognizable - buggy eyes for lots of swapping, frowning for lots of disk activity.

The four time values returned by rstatd cp_time[CPUSTATES] are
the times for each of the valid cpu states, as normally found
in <sys/dk.h>:

#define      CP_USER            0
#define      CP_NICE            1
#define      CP_SYS            2
#define      CP_IDLE            3

This information can be used to paint some pretty good pictures
about cpu utilization.  Some systems (such as those from Convex)
which have multiple CPU's will average the total of all CPU's,
while others will just give overall totals and require you to
divide by cpu count manually, which can be hard if you are truly
running remotely.

If you need details of the meanings of the states post a followup.
