Hey Everyone, this script was very nice but it also had some weird irritations so I reworked it and added: - Allow empty Warning/Critical values - Added Modes so that you can check Disk IOs, Disk Queue, or Disk Wait Times - To see the usage information use check_diskio.sh -h Sorry I don't have this anywhere on the web so I'm just going to paste it here: #!/bin/bash # # Version 0.0.2 - Jan/2009 # Changes: added device verification # # by Thiago Varela - [email protected] # # -------------------------------------- # # Version 0.0.3 - Dec/2011 # Changes: # - changed values from bytes to mbytes # - fixed bug to get traffic data without comma but point # - current values are displayed now, not average values (first run of iostat) # # by Philipp Niedziela - [email protected] # # Version 0.0.4 - April/2014 # Changes: # - Allow Empty warn/crit levels # - Can check I/O, WAIT Time, or Queue # # by Warren Turner iostat=`which iostat 2>/dev/null` bc=`which bc 2>/dev/null` function help { echo -e " Usage: -d = --Device to be checked.
