Unfortunately it's not really possible to record nmon's output to a file the way you desire.<br />
(&quot;topas&quot; followed by &quot;-&quot; is in fact &quot;nmon&quot;).<br />
You can try for yourself (to see that the output isn't really readable):<br />
<br />
export NMON=&quot;m&quot;; nmon -b -B -c 3 &gt;&gt;&nbsp;nmon_m.out<br />
<br />
The above will produce just 3 samples, I think that will be enough for our purpose.<br />
<br />
nmon has a builtin recording facility, but that's a very comprehensive thing.<br />

How about good old &quot;vmstat&quot;? Its output can easily be recorded.<br />
<br />
vmstat 2 1800 &gt;&nbsp;vmstat.out<br />
<br />
Try the various flags of vmstat, if required.

Unfortunately it's not really possible to record nmon's output to a file the way you desire.
("topas" followed by "-" is in fact "nmon").
You can try for yourself (to see that the output isn't really readable):

export NMON="m"; nmon -b -B -c 3 >> nmon_m.out

The above will produce just 3 samples, I think that will be enough for our purpose.

vmstat 2 1800 > vmstat.out

I need a script that will show me what is going on in memory on an aix 6.0 system<br />
<br />
I can run topas - then hit &quot;~&quot; - then hit &quot;m&quot; and get what is going on in memory but need something that produces the same information in a script<br />
<br />
is there a way to script this and get the same information as this plus a short history - say the last hour or so?<br />
<br />
thanks

aix unix memory check

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
