Getting CPU% from a ps command (AIX 5.3)
Hi,

I need write a script that check how much CPU% a particular process is using so I execute something like :
Code:
while :
do
      ps aux |  awk '{ if($3 < 10) {printf( "this process %s CPU: %f and process %d\n",$1,$3,$2)}}'
      sleep 300
done

but issue here is that I compare the number I get from the above command and the output I get from nmon is not even close :
Code:
Top-Processes-(253) ─────Mode=4  [1=Basic 2=CPU 3=Perf 4=Size 5=I/O 6=Cmds]
│  PID       %CPU     Size      Res     Res      Res     Char    RAM      Paging         Command                                                            
│            Used       KB      Set     Text     Data     I/O     Use   io   other repage                                                                   
│  426198    87.2   506400   339408       60   339348       31    1%      0     95      0 db2sysc                                                           
│ 2035930    40.1   282324   250896       60   250836     2328    1%      0     46      0 db2sysc

Does anyone know how from what other source I should get the CPU% so I get a number close like the one given by nmon. thanks.
