diskdevstat
will start the scripts. There are no parameters or options for them. The
output will look similar to top and/or powertop. Here a sample output of
will start the scripts. Both can take up to 3 parameters:
diskdevstat [Update interval] [Total duration] [Display histogram at the end]
netdevstat [Update interval] [Total duration] [Display histogram at the end]
Update interval:
Time in seconds between updates for the display. Default: 5
Total duration:
Time in seconds for the whole run. Default: 86400 (1 day)
Display histogram at the end:
Flag if at the end of the execution a histogram for the whole collected
data.
The output will look similar to top and/or powertop. Here a sample output of
a longer diskdevstat run on a Fedora 10 system running KDE 4.2:
