Reporting › CA Network Flow Analysis Views in CA Performance Center › Calendar Chart (Flow)

Calendar Chart (Flow)

The Calendar Heat Chart (Flow) view shows the recurrence of flows on an interface. Finding a recurring flow pattern can help you to identify the source of performance issues that otherwise might appear to be intermittent. For example, the view can show the hour of each day when flows are highest.

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 CA Network Flow Analysis.

Month, Date, and Day of the Week

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

Hour

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

To see the Calendar Heat Chart view in CA Performance Center, add it to a custom dashboard.
