33 IP Traffic analyzer monitoring and sFlow reports

•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 164). 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:
