Selection of Storage Subsystem  iSCSI  Statistics gives you information about
transfers in the OSI layers 2 to 5. Figure 13-14 on page 332 shows as an example of the
Ethernet MAC statistics in Raw mode.
Transfers can be measured in Raw mode or Baseline mode, the difference between the two
modes is the time since the transfers were counted. Raw mode uses the time since the
controller was started and base line mode use a time that was defined by the user by clicking
Set Baseline. Using this button resets all base line counters to zero and starts counting from
beginning again.
Use the Save As button to save all current statistics in a *.csv file. Raw and baseline mode
statistics for all levels are saved.
