Defining a Statistics Retention Policy

The ARM allows operators to store statistics for up to a maximum of one year (365 days). The statistics are collected every five minutes per Network Topology element and are displayed in the ARM GUI by graphs which help operators analyze network routing.

The statistics are collected by the Routers. The Configurator samples them every five minutes. Session statistics are calculated by the Configurator itself.

➢

To define how long statistics will be stored:

1.

Open the Statistics page (Settings > Advanced > Statistics).
