Utilization (Calendar Chart) Report

The Utilization (Calendar Chart) report maps the utilization percentage of the selected interface over time. Utilization is calculated on either inbound or outbound traffic, depending on the selected Presentation mode.

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.

Follow these steps:

1. Display an interface report in either of the following ways:
   • Locate and click an interface on the Interfaces page.
   • Click an interface link in an existing view--for example, on the Enterprise Overview page.
2. Select Utilization from the report type menu at the top of the page.

   The report page is updated.

3. (Optional) Choose the direction of the traffic by using the Presentation options:
   • Direction In: Show traffic that is inbound on the interface.
   • Direction Out: Show traffic that is outbound on the interface.
4. (Optional) Change the reporting period: Open the Timeframe dialog by clicking the timeframe link.

   The reporting period is the most recent 24-hour period by default.
