AIX normally runs topas in the background all the time. Do &quot;ps -ef | grep topas&quot; and you will see the process.<br />
<br />
If you are not familiar with topas, use the man pages for an overview.<br />
<br />
The output normally goes in /etc/perf/daily, with the output in files ending in .topas.<br />
<br />
You can't view these files directly, but use the man pages on topasout to see how to view the result.

I am familiar with topas but that was not my question<br />
I want to use nmon to capture top cpu activity processes via a script

<div class="content wysiwyg-content">
I have been up the last three nights being paged about high cpu usage on AIX 7.1<br />
I can run nmon the press c then press u and nmon displays the top cpu processes/programs<br />
<br />
is there a way to run that in a script and capture the output?<br />
<br />
any help would be appreciated<br />
I have tried several options to put the info in a file but cannot get the output desired<br />
the summary of top cpu when running the command includes<br />
PID %CPU ResSize Char Command - don't really need the Char column

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
