Interface Utilisation Report

The interface utilisation report shows the interface utilisation statistics for one or more interfaces. By default it will display the averages for input, output, combined and higher-of-in-and-output bandwidth utilisation, as well as exception counts and cumulative exception period.

Exceptions are defined as any of the utilisation readings rising above option util_threshold (default: 80%). The exception period is defined as all the intervals with over-threshold readings. In addition to those raw readings, the labelling of an interface as in exceptional or normal state is controlled by option util_threshold_mincount (default: 1), which defines how many exceptions have to be observed before the interface is labelled "bad".

This report can be further adjusted with these options:

• Option show_threshold (default: true)
  If set to false, no thresholds are shown; instead the bandwidth, average traffic and average utilisation are presented (plus a shortened report period column).
• Option show_only_util (default: false)
  If show_treshold is false, and if show_only_util is set to true, then only bandwidth and average utilisation are shown (ie. average traffic is omitted).
