12.3.2 View iSCSI Statistics
The View iSCSI Statistics link gives you information about packets in the OSI layer 2 to 5.
Figure 12-20 on page 283 shows as an example, the TCP/IP statistics in base line mode.
Packets can be measured in RAW mode or base line mode - the difference between the two
modes is the time since the packets are 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
the Set Baseline. Using this button resets all base line counters to zero and starts counting
from scratch.
Use the Save As... button to save all current statistics in a plain text file. RAW and baseline
mode statistics for all levels are saved.
A link to the online help is provided to translate column names into more meaningful names
for each statistic type.
