KPIs & KQIs

• Number IF Down: Calculated. The number of interfaces that were once known to be up to DataMiner, but which are currently down.

  Calculated by counting the number of DCF interfaces above the utilization threshold.

  • In utilization calculated from In octets OID 1.3.6.1.2.1.2.2.1.10.
  • Out utilization calculated from out octets OID 1.3.6.1.2.1.2.2.1.16.

For example, if a source is known to be connected to 10 destinations with function "CCAP Core", then there will be 10 incremental hops for the source.
