Service Performance Summary (NSP) report
Service Performance Summary (NSP) report overview
The Service Performance Summary (NSP) report offers a concise overview of jitter, latency, and packet loss metrics for services. Within the report, a table is presented, detailing key statistics such as average, maximum, and minimum values for each metric. The Service Performance Summary (NSP) report differs from the Service Performance Summary report by including available data for NEs managed by the NFM-P or MDM. The report shows a summary of jitter, latency, and packet loss for services.
Note: If there is no data in any one of the stats for TWL/TWL Loss and DMM/SLM session accounting stats, the report shows -1.0 in red.
If the received packet is greater than the transmitted packet, then the packet loss gives a negative value, which is displayed as 0.0 with drill down.
Limitations
Report limitations include:
-
The report for MD SR NE supports only the services which are associated with endpoints (not MEP).
-
When the report is exported to the RTF or DOCX file type, some columns may not display or there may be a problem with the table border.
Prerequisites
The following prerequisites are required in order for the report to be generated:
Either of the following sessions must be performed in the NSP or NFM-P for the report to be created:
-
A DMM session must be defined with accounting enabled in either MDM-managed or NFM-P NEs. DMM Sessions will be created with L2 services.
-
A TWAMP-Light session must be defined with accounting enabled in either MDM-managed or NFM-P NEs. TWAMP Light session will be created with L3 Services.
Note: Complete PM is not supported for SAR NEs.
The following table describes the subscriptions that must be added to the NSP to collect telemetry statistics, and the aggregators that must be enabled to run the report for other granularities.

The following table describes the aggregation rules that must be enabled and the accounting policies that must be configured for the NEs on which statistics are to be collected; see the NSP NFM-P Statistics Management Guide for information about configuring an accounting policy. To view the report for granularities other than raw data, the aggregation rules must be enabled; see How do I configure analytics aggregation?.

Use cases
QoS analysis - identify potential service impacting issues based on thresholds for latency, jitter and packet loss on services.
