"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Which version of SunOS?

For SunOS 5.x
CPU: psrinfo -> show cpu information (number of cpu/speed/status)
MEM: Check in "dmesg" or "/var/adm/messages".

Number of logged in session you must use "ps" and "grep" telnet session, or use "netstat -na | grep 23" (Check number of connection on port 23-port telnet)

TIP: If you use sun4d, or sun4u you can use /usr/platform/sun4d<or sun4u>/sbin/prtdiag. It will show many usefull information about CPU, Memory, etc.
