When I perform the command
iostat -x | grep -P 'Device|x.\s'
I get the following columns as output
device rrqm/s wrqm/s r/s w/s rsec/s wsec/s avrq-sz avqqu-s await svctm %util
What does each of these column mean?
I know RTFM is not the answer you are looking for, but this time it is appropriate. Try man iostat
, all the values are explained there. In case you are somehow missing the man pages, here's a webified version, although your Linux distribution might have a more current version of that man page.
