System Resource Utilization

Hi All,
I'm planning to write a script that will collect system resouces utilization every one hour. System resource utilization like I/O, Memory, and CPU - do you have any idea which DCL or lexical I can get this information?

Hope to get reply on this.

regards,
ronald

Re: System Resource Utilization

Ronald,

a lot of this really comes back at yourself!

I know, we got a similar request 9 years ago.
We made a preliminary small DCL, presenting some data.
Those lead to more precise info requests, the sript evolved accordingly, and now it really presents everything that "theÿ" consider worthwhile.

Start i=out with a simple script that collects what they want. Put that into a temporary file, do it again after , compare the values, present the differences.

Now for the big deal: "What do they want to see specifically".
Your script wi;ll evolve quickly, and it will be uniquely tailored to your site's desires.

You'll see: it quickly will become THE most important piece of software.
But: very quickly, just BECAUSE of its predictability, the interest will whither, and all you are left with is a nice set of metrics.

But, whenever any question arises, you now have the ability to produce a wealth of historic data.

But, only YOU can estimate what is important at YOUR site!

ymmv.

Proost.

Have one on me.

Re: System Resource Utilization

The classic tools for this are MONITOR and parse the text files, T4 and now you can use
TDC and GETRMI.

TDC

T4
http://h71000.www7.hp.com/openvms/products/t4/

You can get some basic info from f$GETSYI, f$GETJPI. See
http://dcl.openvms.org
for plenty of examples.

Re: System Resource Utilization

F$GETSYI() offers some potentially useful
items:

FREE_PAGES
MEMSIZE

PAGEFILE_FREE
PAGEFILE_PAGE

(PAGE_SIZE)

You'd need to do your own sampling.

Most of the potential items are discussed in
more detail in the documentation for $GETSYI:

Re: System Resource Utilization

Ronald,

nowadays, I would strongly suggest to use T4 on any recent OpenVMS Alpha or OpenVMS I64 system. This is a low overhead performance data collector used by OpenVMS engineering since a couple of years. It can automatically manage the collected data and present daily graphical overviews via e-mail. If you then need to focus on more specific data, it's just there and you can manually analyze the data using TLviz, which provides graphical output much better than any home-grown DCL script could do.

T4 is very easy to install and configure.
