How End Date/Time and Span works:
Assume you have seven days of sFlow data from June 1 through 7. You want to view the first four
hours of data during June 2. From the End Date/Time lists, select 6/2 for day and 4 am for time. In
the Span list, select 4h. The resulting report shows four hours of data for June 2, beginning at 12
am and ending at 4 am.
Also, if you select 1, 2, 4, or 6 hours for span, top talkers are shown as stacked bar graphs; each
bar represents two minutes of data. For example, each bar below represents 2 minutes of data.
Each bar is divided into the top talkers for that 2-minute period.
Measure list
Select how data is to be sorted: Bytes or Frames. Frames is the default.
Refresh list
If you select 12 hours or 1 day for span, each bar represents one hour of aggregated data and a
bar represents each top talker. For example, each set of 6 bars represents an hour of data; one bar
represents a top talker.
Select the refresh rate for the graph from the list. The default refresh rate is configured in the
configuration.properties file.
NOTE
The sFlow Monitoring report automatically refreshes the displayed information as specified in the
Refresh Rate box. Once any of the Monitoring Actions arrow is clicked, this auto-refresh action fails.
This is true even if you click Cancel in the confirmation dialog. You must initiate a refresh by changing
the values in any of the header selections for the auto-refresh to start working again.
2D or 3D button
Click this button to toggle between a two-dimensional and three-dimensional graph.
Graph check box
Select this check box if you want data to be presented in a graph format.
Table check box
Select this check box if you want data to be presented in a table.
If Table (box) is enabled, a table shows details for the top resource users, beginning with the
heaviest user. If you are viewing a report for a device group, the top users in the group are
presented. If you are viewing a report for a device, the top resource users for the device are listed.
Traffic for the remaining users on the network appear at the end of the table, along with the traffic
total.
If the table is displayed, you can also do the following to manage a port that appears on the report:
• Disable a port.
• Enable a port.
