What's New in System Accounting
This section describes new or changed features in system accounting in the Solaris
Solaris Process Accounting and Statistics Improvements
Solaris 10: Changes have been made to the internals of the load averaging, cpu usr/sys/idle, and
accounting functions. Microstate accounting has replaced the old accounting mechanism and is enabled
by default all of the time. As a result, you might notice slightly
different process usage and timing statistics.
Switching to microstate accounting provides substantially more accurate data about user processes and
the amount of time they spend in various states. In addition, this information
is used to generate more accurate load averages and statistics from the /proc
file system. For more information, see the proc(4) man page.
