Hi
It was me, not Radoslav, who put this "disputed" question .
The idea not from the z/OS side, but we have a client/server object
oriented product, run in several platforms, and it has a
feature to display the CPU utilization, disk-load, network-load etc. etc.
So maybe the client user has no idea, where the server is running .
So the guys from the PC , AIX development side asked if we can also
produce this information.
If you get a question like this, i.e it is possible in other platforms,
you try to find a solution, in any means ...
The first idea was, to get this information from RMF, but for this, it
was necessary to activate the RMF data gathering, by the customers site.
A while ago someone here , in the list , pointed to the RCT control
blocks, and from the Resource Manager control blocks, it was
simple to get the CPU utilization , and channel load.
So we are here now, for me the main motivation, "it is possible on other
platforms", but if it is not possible, or not so simple, I will have no
problem to say "impossible".

Radoslaw,
What should have been asked is Why.
Unless you are writing a performance monitor (again why) there is no likely
reason as to why they need to know.
There are a lot of people that think they need to know this type of info,
especially application types who think they should programically be able to do
better than Z/os does.
It should be strongly discouraged as control blocks change and then the program
becomes dependent on the then current level of the OS. It be ones a nightmare
that will come back to haunt everyone and for no good reasons.
