Chapter 8: Statistics

Viewing access statistics

The statistics groups can be viewed all together or individually, as well as on a LUN (logical drive) or Port basis.

The View Access Statistics screen is accessed by going to the Statistics Types menu (see “Viewing all statistics” on page 155), then selecting View Access Statistics.

Each time statistics are viewed, the controller first outputs the current time and the time since it was last reset. The statistics can be reset at any time. This is useful in determining the access pattern for a particular test or period of time.
