Flows Report

A Flows report presents a trend plot with information about all the flows that enter and leave the selected interface. A Flows report helps you find patterns or anomalies.

Flows do not always equate with traffic volume or traffic rate. A flow can represent a single packet, or it can represent a 1-MB flow of data that occurred during a 1-minute interval. Flow rate can indicate the load on the Harvester, however. Viruses typically generate large increases in flow counts.

To display a Flows 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 Flows from the report type menu at the top-left corner of the page.

   The report page is updated to show flow trend charts.

3. (Optional) Change the data data measurement type by using the Presentation options:

   Rate (default setting) or Volume

   Each option displays trend charts of data that is inbound and outbound with respect to the selected interface.

   You can also select Show Baselines to view +/- 1 Standard Deviation. The baseline is computed by calculating the average and standard deviation for a maximum of ten samples (the last six weeks and the last four days). This rolling baseline feature provides a visual representation of a current and historical trend overlay. When a current trend line is above or below the baseline, the performance is out of the norm. When the current trend is within the baseline, the performance is within the range of historical behavior.

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.
