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.
Statistic Description
Total Read Commands This is a count of the total number of read accesses (for
all ports and logical drives) that have occurred since the
controller was first powered on. This value is never reset
and indicates the number of commands that were sent
to the controller from the time it was manufactured.
Total Read Transfer This is a count of the total number of 512-byte blocks
(for all ports and logical drives) that have been read
since the controller was first powered on. This value is
never reset and indicates the amount of data transferred
by the controller from the time it was manufactured.
