How can I look at what my system is doing?
The best tool for monitoring your system is HP GlancePlus. In the U.S.
call 800.237.3990 for a trial version. Outside the U.S. contact your HP
sales representative. HP sells other performance tools as well including
HP Performance Collection Software, HP PerfRX (for long-term performance
analysis of a single system), and HP PerfView which runs under OpenView
(for simultaneous monitoring of a network of systems including HP-UX,
Solaris[TM], and AIX[R].
A couple cheaper, but less robust, options are the sar(1M) and top(1)
On 9.x systems, you can use /usr/contrib/bin/monitor.
