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:
\n# top -b -c 10 > topfile.txt &
\nthen parse the output file\/s in a script
\n#!\/bin\/ksh
\necho “DATE,CPUIDLE,ME MUSED,MEMFREE”
\n(X=0;
\nB=””;
\nawk ‘NF!=12 && length>0’ top* | grep -iv defunct | while read line;do
\nL=`echo “$X % 5” | bc`
\nif [ $L -eq 0 ];then
\necho “$B”
\nB=””
\nfi
\nB=`echo $B$line | sed ‘s\/ \/_\/g’`
\nX=`echo “$X + 1” | bc`
\ndone ) | awk -F’_’ ‘{ print $3 “,” $31 “,” $41 “,” $43 }’
\nThis was tested on a linux Suse 9 on IBM OpenPower equipment.

\nCreating a whole root zone
\nA whole root zone is a zone that has copies of packages in its own filesystem, not mounted as loopback.
\n# zonecfg -z wrzone
