Hey guys,
I was task to look at a couple DNS servers for a co worker, Now they are running Solaris 2.6 on some Ultra 10 systems. How can I check the kind of load these systems are taking, I know that I can look at the network size and how many zones these servers are SOA of, but I looking in a hardware perspective
Pick up Adrian Cockroft's Sun Performance and Tuning book. It will be the best book for learning about performance monitoring on your older than Solaris 10 systems. For Solaris 10, I'm using Solaris Performance and Tools from Richard McDougall et.al. So far it's been a big help in tracking down problems.

I would start with the basic perf tools: top, iostat, vmstat, etc.
top isn't typically installed on Solaris 6 by default but you can get it from the sunfreeware site. iostat and vmstat (and sar, etc) are good tools but if you're not familiar with performance monitoring you may not really know what you're looking at or even how to use it correctly. Specifically for a Solaris 6 system, I'd suggest chasing down a copy of Adrian's book. It's even been helpful for HP, Linux and AIX systems however since I'm generally a Solaris admin, it's the book to have for performance monitoring on older Solaris. Heck, a quick look at Amazon shows a copy going for $1.39 not including shipping (usually another $3.50 or so). That's a great buy. He also discusses kstat and tracking down I/O hogs.
