Is there anyway to get the output of iostat -m and add only the column await from the extended output in realtime? I know this question sounds nutso but I need to be able to get all those column in realtime without outputing to a file or running iostat twice since that would give misleading results. This is centos 6.2 iostat 9.0.4. kernel 220.127.116.11. So to summarize I need this.
Device: tps MB_read/s MB_wrtn/s MB_read MB_wrtn sda 0.56 0.00 0.00 324 485
and I need to add await to it so it looks like this.
Device: tps MB_read/s MB_wrtn/s MB_read MB_wrtn await sda 0.56 0.00 0.00 324 485 10.72
Am I dreaming? I'm I looking at this the wrong way? Do I need to compile my own iostat?
Thanks in advance.
