I want to monitor all the processes that are loaded in µClinux (CPU usage, memory usage,...).

Hi,

To do so I executed the ps command, it gives all the stuff I need, unfortunately there is no top command so I got to write a script to execute the ps command every 3s and write results to a file.

If anybody could help in that, that&#39;s gonna be cool.

Warm Regards.

Hi MFM,

I haven&#39;t tried it yet, but it looks like top command may already have been been ported http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

* Follow step 13 here...

http://forum.niosforum.com/forum/index.php?showtopic=3174# (http://forum.niosforum.com/forum/index.php?showtopic=3174#)

* Select Miscellaneous Applications --> Propcs tools --> top

Oops. I tried building the top and setserial apps from dist-test, however no binaries were generated.

Any ideas?

Hi,

well, I wrote that script and it works fine with one exception:

I want to launch the ps command every 3s and save results in mfm.txt till the q key is pressed.

I&#39;m still testing it in Redhat before implementing it in µClinux.

The only problem is how to get the q key stopping the execution of the script

# ##################################

# !/bin/sh

touch mfm.txt

until [ "$*" = "q" ];

do

sleep 3

date >> mfm.txt

ps >> mfm.txt

echo " " >> mfm.txt;

done

# ##################################

Can anybody help me with that ?

Warm Regards

Hi,

I&#39;ve tried to execute that script under µClinux after changing the sleep 3 command, which isn&#39;t implemented in µClinux, by the following:# ###############

for ((a=1;a<300;a++))

do echo

done# ###############

But unfortunately it won&#39;t work http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif

I&#39;m getting some "syntax error".

Can anybody help me with that.

Warm Regards

why are you doing this when you can just get &#39;top&#39; from busybox?

Hi,

that&#39;s cause I spent a lot of time trying to compile it but all I got is a lot of errors

maybe you can help.

This is the console output (I&#39;m under Windows)

I succeded in building that one but when I launch it, µClinux reboot.

I tested it again and again and it&#39;s always the same!!!!!!!

Any idea?
