What command line utilities come standard with sunos to do system monitoring?

I've been able to find prstat, but I would like something that will tell me memory usage and IOWAIT as well.

It looks like this particular machine uses sunos 5.8

vmstat, iostat, sar, ... prstat does tell you about memory usage. Also, time for an update, 5.8 is getting really old. – Mat Sep 12 '12 at 20:06
You don't need to include "solaris" in your title, that's what tags are for – warl0ck Sep 13 '12 at 7:25
What you have is actually Solaris 8. – bahamat Sep 13 '12 at 7:49

There are plenty of monitoring CLI commands with Solaris. They are easy to find as almost all share the stat suffix:

  • vmstat
  • mpstat
  • iostat
  • netstat
  • lockstat
  • nfsstat
  • prstat
  • busstat
  • cpustat
  • kstat
  • sar
  • swap

kstat (or the equivalent netstat -k) provides all of the kernel statistics in raw form.

About the IOWAIT statistic, note that the fact it was often poorly understood, wrongly interpreted and meaningless with fast and/or multi core / multi threaded CPUs, it is no more reported by vmstat on modern (10+) Solaris releases.
