You can display graphs for each of the measured attributes showing:
•
Top Sources (default)
•
Top Destinations
•
Top Connections
•
Top Protocols
More than one graph can be displayed at a time, so you can look at the values for multiple attributes for each
segment.
Since Traffic Monitor presents real-time information, the data will be "moving" on your graph. Data is graphed and
updated every minute. The Top 5 View displays up to 60 data points. That is, you can view the most recent hour of
activity.
The bar on the right in the graph represents (up to) the top five nodes for the latest minute graphed. This bar is
selected by default and is indicated with a black "tick" and the time sampled above it. The color-coded stacked bars
represent the activity for up to the top five nodes and "other" nodes for the selected attribute and segment. The non-
selected bars in the graph show how these top talkers have behaved over the past hour. This lets you view trends
over the last hour for the five top talkers of the selected minute.
The yellow and the red horizontal lines on the background of the graph represent the warning and critical values,
respectively, for the selected segment. These lines only appear when the graph scale is high enough.
The colors are in the same order as they appear in the legend, that is, the node with the greatest activity is
represented by the color at the bottom of the stacked bar. The white portion of the stacked bar represents the top
talkers in minutes who are not top talkers in the selected minute; the dark gray portion of the stacked bar represents
all other activity. You can visually trace the same color across the graph to see trends of activity over the past hour.
Information for the top five colors in the legend identifies the source and destination nodes of the top five
connections for every data point on the graph. The information in the color legend will change as the data points are
graphed. Depending on the parameters you have selected, the information provided by the legend can include:
•
The layer 3 or layer 2 (MAC) address
•
The network protocol or service being used. The highest network protocol for the communication path is
displayed.
•
The direction of data flow (the source and destination nodes)
