    - iostat can provide the values
    - A graphing tool like cacti or collectd can collect those and show trends
    - and a monitoring tool like nagios, xymon can alert if thresholds are reached

    Cause of disk utilization is...
    programs need IO for their tasks

    How to resolve:
    Investigate what needs IO and why and in which way.
    Then either optimize the config or spread the load (e.g. use different spindles for logs, input data, output data or add more discs/controllers or use more machines)

    You must always face the curtain with a bow.
