Statistics
Frame Size (Bytes) Packets
The Frame Size (Bytes) Packets fields indicate the number of packets (including error packets) processed by the network segment that were of the noted length, excluding framing bits but including frame check sequence bits. Packet sizes counted are:
•64
•
•
•
•
•
The percentages displayed to the right of the numerical values for these fields indicate what percentage of all packets transmitted on the network segment were of the noted size. Unless the network segment has experienced a significant number of runts and/or giants (which are not counted in this group), these percentages will add up to 100. The pie chart in the center of the window provides a graphical view of the percentage breakdown; colors in the pie chart correspond to colors in the percentage display boxes. Values listed to the right of the pie chart indicate peak delta values recorded since the statistics screen was launched, and the date and time they occurred.
Viewing Total, Delta, and Accumulated Statistics
By using the Total, Delta, and Accum option buttons located at the bottom of each Statistics window, you can choose whether to view the total statistics count (since the last time the device was initialized), the statistics count during the last polling interval, or a fresh accumulation of statistics begun when the Accum button was selected.
The statistics windows use the polling interval you have set for the monitored device via
TIP the Device Management page of the Options window. See the User’s Guide for more information on setting the Chassis Manager polling interval.
To choose Total, Delta, or Accum:
1.Click on the Total option button; after the completion of the current polling cycle plus one complete polling cycle, the screen will display the total count of statistics processed since the entry was created or since the device was last initialized, whichever is most recent. These totals are updated after each polling cycle.
2.Click on the Delta option button; after the completion of the current polling cycle plus two more polling cycles, the screen will display the count of statistics processed during the last polling interval. These counts will be refreshed after each polling cycle.
