OAM-PM Latency (NSP) report
General information
The OAM-PM Latency (NSP) report differs from the OAM-PM Latency report by including OAM data for NEs managed by the NFM-P and MDM (model-driven Nokia NEs). The report can be run by itself or as a drill-down from an OAM-PM Network Site Summary (NSP) report. The report shows the graph of latency for a selected session during a specified time period. The report includes the following session types:
For raw granularity, the report displays data based on startTime from PM session-based statistics. For other granularities (hourly, daily, and monthly), the report displays based on timeRecorded. The difference in data is between the raw and granularity reports for Wavence NEs.
Use cases
QoS analysis—Identify potential service impacting issues based on thresholds for latency, jitter, and packet loss between specific NEs.
Prerequisites
The following sessions need to be performed in the NSP and NFM-P for the report to be created:
-
a DMM session must be defined with accounting enabled in both the MDM-managed and NFM-P NEs
-
a TWAMP-Light session must be defined with accounting enabled in both the MDM-managed and NFM-P NEs
-
You must enable aggregation using NSP. For more information, see the Telemetry information on the Network Developer Portal and the NSP Data Collection and Analysis Guide.
