OAM-PM Top N Worst Sessions (NSP) report

Overview

The OAM-PM Top N Worst Sessions (NSP) report differs from the OAM-PM Top N Worst Sessions report by including OAM data for NEs managed by the NFM-P and MDM (model-driven Nokia NEs). The report shows the worst case OAM-PM sessions over a specified time period, grouped by session.

The report includes the following session types:

Use cases

QoS analysis—Identify potential service impacting issues between specific NEs.
