IP Traffic analyzer monitoring and sFlow reports

If the Graph check box is selected, a graph appears below the report header. Data for the most
current time on the report is displayed when a report is requested. The navigation arrows in the
report header allow you to display the next or previous panel of the report. Refer to the
on page 1077 for information on what the graph represents.
There are differences in the graphs for periods up to six hours and for the 12 and 24 hour graphs:
•
For periods up to 6 hours, the graph shows stacked bars. Each bar represents a flow
aggregated for a 2-minute period. Each stack represents all the flows in the system aggregated
for a 2-minute period.
•
The 12 and 24 hour graphs show bars (not stacked bars). Each bar represents a flow
aggregated for a 1-hour period. There are six bars to a set, starting with red and ending with
gray. Each set represents all the flows in the system aggregated for a 1-hour period, beginning
with the time shown on the x-axis. You see this time halfway between the set of six bars.
The first five colors used on the graph represent the top five resource users. The last color (gray by
default) represents all the remaining users in the device group. The color legend defines the
individual source and destination of the traffic.
If Table is enabled, a table appears under the graph and presents details about the top users. The
number of pairs displayed depends on the value of the MaxPairsToShow parameter on the Options
dialog box (refer to
“Configuring sFlow monitoring preferences”
on page 171). Combined usage by
all remaining users and a total for all users appear at the end of the table. The number of top
resource users shown and the number of rows displayed on a report depends on how sFlow
parameters in the Options dialog box are defined.
Refer to the following sections to interpret the table:
•
•
•
“Viewing all Layer 3 and Layer 4 traffic”
•
“Viewing all IPv4 Layer 3 or Layer 4 Top Talkers”
•
“Viewing IPv4 – top TCP talkers”
•
“Viewing IPv4 – top UDP talkers”
•
“Viewing IPv4 – top ICMP talkers”
•
on page 1087, discusses the following reports:
-
Top IPV6 Talkers using all Layer 4 services
-
Top TCP Talkers
-
Top UDP Talkers
-
Top ICMP Talkers
-
Top IPV6 Talkers of all Layer 4 service, excluding TCP, UDP, and ICMP
•
“Viewing other Layer 3 or Layer 4 Top Talkers”
•
“Enabling and viewing TCP reports”
•
The sFlow report that you request may not display all the data collected. The reports may be
truncated if there are more rows than the limit specified in the Options dialog box file. To view the
entire report, you must export it to a tab-separated file.
