To monitor a machine’s performance, in a very raw manner, you can run top in batch mode and redirect it to a file, like:
# top -b -c 10 > topfile.txt &
then parse the output file/s in a script
#!/bin/ksh
echo “DATE,CPUIDLE,ME MUSED,MEMFREE”
(X=0;
B=””;
awk ‘NF!=12 && length>0’ top* | grep -iv defunct | while read line;do
L=`echo “$X % 5” | bc`
if [ $L -eq 0 ];then
echo “$B”
B=””
fi
B=`echo $B$line | sed ‘s/ /_/g’`
X=`echo “$X + 1” | bc`
done ) | awk -F’_’ ‘{ print $3 “,” $31 “,” $41 “,” $43 }’
This was tested on a linux Suse 9 on IBM OpenPower equipment.

Creating a whole root zone
A whole root zone is a zone that has copies of packages in its own filesystem, not mounted as loopback.
# zonecfg -z wrzone
wrzone: No such zone configured
