on hpunix cpu usage fields
i have found a structure contained in file global _pstat_body.h at the path
/usr/include/sys/pstat which is
named __pst_dynamic . A field by name psd_cpu_time is
an array of maximum cpu states the kernel supports .
i,e psd_cpu_time [PST_MAX_CPUSTATES] specify all
the cpu timings in an array . i wanted to know which
index into the array spesify which element state i,e
whether the psd_cpu_time[0] is cpu time in user mode
and psd_cpu_time[1] is cpu time in kernel mode and so on .

In response to your cpu usage answer
I too read sys/sysinfo.h but , if we put these values to access the repective time fields in the array pst_cpu_time which is a member of the structure pst_dynamic values doesn't seem to match, why is like this? (0 Replies)

On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

CPU(1) General Commands Manual CPU(1) NAME
cpu - connection to cpu server SYNOPSIS
cpu [ -h server ] [ -c cmd args ... ] DESCRIPTION
Cpu starts an rc(1) running on the server machine, or the machine named in the $cpu environment variable if there is no -h option. Rc's standard input, output, and error files will be /dev/cons in the name space where the cpu command was invoked. Normally, cpu is run in an 81/2(1) window on a terminal, so rc output goes to that window, and input comes from the keyboard when that window is current. Rc's cur- rent directory is the working directory of the cpu command itself. The name space for the new rc is an analogue of the name space where the cpu command was invoked: it is the same except for architecture- dependent bindings such as /bin and the use of fast paths to file servers, if available. If a -c argument is present, the remainder of the command line is executed by rc on the server, and then cpu exits. The name space is built by running /usr/$user/lib/profile with the root of the invoking name space bound to /mnt/term. The service envi- ronment variable is set to cpu; the cputype and objtype environment variables reflect the server's architecture. FILES
The name space of the terminal side of the cpu command is mounted on the CPU side on directory /mnt/term. SOURCE

Binds and mounts done after the terminal lib/profile is run are not reflected in the new name space. CPU(1)
