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 qualifying DCF interfaces with Operational Status equal to "Down".
Number IF Over-Utilized: Calculated. The number of interfaces that are over-utilized according to the utilization threshold configuration.

Calculated by counting the number of DCF interfaces above the utilization threshold.
Number IF with Errors: Calculated. The number of interfaces with 1 or more errors (In/Out).

Function: Calculated. The element CIN function as specified in the associated custom property.

Retrieved from the CIN FUNCTION custom property.
Node Leaf: Calculated. Table displaying all CIN (Converged Interconnect Network) entities operating as node leaves, which means they should be directly connected to at least one CCAP core.

The table displays all CIN entities with Function equal to "Node Leaf".

Note that multiple connections (interfaces) between a source and a destination are counted as a single hop as the hop count is only affected by the existence of at least one connection between the source and the given destination. 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.

This status is based on the utilization threshold set for each entity type.
