Utilization (Calendar Chart) Report

The Utilization (Calendar Chart) report provides information about the inbound or outbound utilization for the selected interface by mapping the utilization percentage on a calendar chart.

Excessive utilization of an interface is shown as a block of red that extends across the column for the day and across the rows for the time of day. Low utilization is shown in green. Varying shades of each color indicate the severity. Each severity range color corresponds to a range of utilization values, which are calculated as percentages of total capacity. The legend shows how the colors are used in the utilization calendar chart.

To display a Utilization report, start from an interface report.

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-left corner of the page.

   The report page is updated to show utilization data as a calendar chart.

3. (Optional) Choose the direction of the traffic to display by using the Presentation options.
   • Direction In: Show traffic that is inbound to the interface.
   • Direction Out: Show traffic that is outbound from the interface.

   The currently selected option is highlighted and is marked with a blue arrow.

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.
