Interface Capacity Report

New in version 3.0.8. Please note that the precise content of this report is subject to change.

The interface capacity report displays a comparison between configured interface speeds and observed actual bandwidth figures.

For each selected interface, it shows the configured input and output speeds, the observed maxima of input and output bandwidth for the report period, and the 95th percentile of the interface utilisation.
Before version 3.0.14, the 95th percentile for combined interface utilisation was shown (Combined utilisation in this report means the set of averages of each input and output utilisation reading). From 3.0.14 onward, you can select from three options: the 95th of combined utilisation, two separate columns for 95th of input and output utilisation, or three separate columns for 95th of input, output and combined utilisation.

In the HTML output format all interface speed and bandwidth figures are auto-scaled and shown with the most appropriate unit, whereas CSV and XLSX outputs contain the unscaled data in bits per second.

From version 3.0.10 on this report offers optional embedded graphs of each interface's capacity. These graphs show the observed input and output bandwidth (input in green, output in blue), and the higher of the configured in and out speeds as a red warning line. If the configured input and output speeds are identical, the 95th percentile of the combined interface utilisation is also shown as a dotted line.

The default choice is to include graphs but you can change that using the report option embedgraphs. In the GUI this option is named "Include Embedded Graphs". The graph contents are not configurable, but the graph size can be adjusted using the configuration option opreports_embedded_graph_size (default: 600 x 150 pixels).

As of opReports version 3.1.4 the Interface Capacity Report now has the 95th display format option. This option is set under advanced features when generating the report and can display as Percent, Bandwidth (bit/s), or both Percent and Bandwidth.
