vmstat and column
try this:
vmstat -w 1 5this works fine in vm, but when in physic machine which has large memory the columu of cpu maybe not looks as better as in vm.
The reason this happens is that column waits to gather as much input as possible on which to base its column guesses. It has no way of knowing that the data pattern repeats every second.
You can approximate what you want to do by running this:
for i in 0 1 2 3 4 5 6 7 8 9; do iostat | column -t; sleep 1; doneEDIT
Thanks to a couple of suggestions from Dennis:
for i in {0..9} ; do iostat 1 1 | column -t; sleep 1; doneThe only difference from the original is that the first header line is repeated every second. Some footwork with sed or grep could take care of that.
