7. HP-UX
Gurus,
Having a GS1280 box with OSF1 v5.1 installed (16 processors), the run queue value from the vmstat command reports a very high value (about 25 to 30). Does this reflect a CPU bound system. Note that the average CPU utilization is about 60 % which means that the CPU is not that loaded.

I am new to Unix and script writing so I was wondering if this would be possible and how I might do it.

SADC(8) Linux User's Manual SADC(8)
NAME
sadc - System activity data collector.
SYNOPSIS
/usr/lib/sa/sadc [ -I ] [ -V ] [ -x pid ] [ -X pid ] [ interval [ count ] ] [ outfile ]
DESCRIPTION
The sadc command samples system data a specified number of times ( count ) at a specified interval measured in seconds ( interval ). It
writes in binary format to the specified outfile or to the standard output. If outfile is set to -, then sadc uses the standard system
activity daily data file, the /var/log/sa/sadd file, where the dd parameter indicates the current day. When the count parameter is not
specified, sadc writes its data endlessly. When both interval and count are not specified, a dummy record, which is used at system startup
to mark the time when the counter restarts from 0, will be written. For example, one of the system startup script may write the restart
mark to the daily data file by the command entry:
/usr/lib/sa/sadc -
The sadc command is intended to be used as a backend to the sar command.
Note: The sadc command reports only local activity.
OPTIONS
-I Tell sadc to report statistics for all system interrupts. By default, sadc only reports statistics for the total number of inter-
rupts.
-V Print version number and usage then exit.
-x pid Tell sadc to report statistics for the process whose PID is pid.
-X pid Tell sadc to report statistics for the child processes of the process whose PID is pid. The SELF keyword indicates that statistics
are to be reported for the child processes of the sadc process itself.
EXAMPLES
/usr/lib/sa/sadc 1 10 /tmp/datafile
Write 10 records of one second intervals to the /tmp/datafile binary file.
BUGS
/proc filesystem must be mounted for the sadc command to work.
All the statistics are not necessarily available, depending on the kernel version used.
FILES
/var/log/sa/sadd
Indicate the daily data file, where the dd parameter is a number representing the day of the month.
/proc contains various files with system statistics.
