Reporting › Interface Context Views › Stacked ToS Trend

Stacked ToS Trend

The Stacked ToS Trend views show the interface traffic for the top ToS, including the time the traffic occurred.

The view shows a timeline of the data rate, interface capacity utilization, or data volume for the top ToS values in use during the reporting period--up to a maximum of ten ToS. The view includes the following information:

Identifier

Consists of the router name, interface name, and interface description (under the view title).

ToS Bands

Show the data rate, data volume, or interface capacity utilization for each Top N ToS that is associated with traffic on the interface.

Time (All Views)

Point in time during data transmission--expressed in hours and minutes (X-Axis).

Volume (Rate or Bytes)

Data volume at each point in time--for example, expressed in thousands of flows in a Rate view or kilobytes in a Bytes view (Y-Axis). Depending on the data direction, the data volume is inbound to the interface, outbound from the interface, or both inbound and outbound. Rate is calculated by dividing the number of flows by the elapsed transmission time.

Percent (Utilization)

Percentage of the total interface capacity that the ToS uses (Y-Axis). The utilization percentage is calculated by dividing the data rate by the data speed, as measured on inbound traffic, outbound traffic, or all traffic.

Legend

Identifies the ToS for each color band by ToS number and label (bottom of the view).

By default, views and reports show the most recent 24 hours of data.
