Real Time?  Nothing is real and there's never enough time.

I'll assume that you want tools for OSR5 (Open Server 5).

Start with sar.  There's quite a bit on sar in the SCO documentation.
Getting it setup for 24hr data collection requires a bit of tweaking:
        http://www.cruzio.com/~jeffl/sco/sar24hour.txt
There are also tools for interpreting the results.  See:
        http://www.sarcheck.com
There's a Sarcheck Lite on the Skunkware 99 cdrom.

For generating real time statistics and traffic graphing, there are
various SNMP (Stupid Network Management Protocol) tools.  SCO's SNMP
implimentation sucks but can be convinved to function.  See:
        http://www.cruzio.com/~jeffl/sco/snmp_install.txt
To extract the SNMP data and graph the results, use MRTG (Multi-router
traffic grapher).
        http://www.mrtg.org
        http://ee-staff.ethz.ch/~oetiker/webtools/mrtg/users.html

Incidentally, real time means that the system will service an IRQ in a
guaranteed minimum amount of time.  I'm sure this is not what you
meant.  Any additional question, please clarify what you are trying to
accomplish.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
