Calendar Chart (Flow)

The Calendar Heat Chart (Flow) view maps the utilization percentage of the selected interface over time. The example graphic shows the view in the CA Performance Center Console.

The Calendar Heat Chart shows when traffic occurs.

This view makes it easy to detect recurring data patterns. Finding a pattern can help you identify the source of high traffic rates and potential performance issues. You might discover that the high traffic rates you thought were intermittent actually follow a pattern. The view can show the hour of each day when utilization is the highest, for example.

Each color represents a severity range that is calculated as a percentage of total capacity. High utilization is shown in orange and red. Low utilization is shown in green and blue.

The view includes the following information:

Identifier

Consists of the router name, interface name, and interface description (under the view title). The interface description consists of the ifDescr value by default, so it may be slightly different than the interface description that is shown in the NFA console.

(NPC) The identifier line also includes the interface speed.

Month, Date, and Day of the Week

Denote the day that the traffic occurred (X-Axis columns).

Hour

Denotes the hour of the day that the traffic occurred (Y-Axis).
