Service Performance Details (NSP) report

Service Performance Details (NSP) report overview

The Service Performance Details (NSP) report differs from the Service Performance Details report by including availability data for NEs managed by the NFM-P only or MDM (model-driven Nokia) only. The report displays the latency, jitter, and packet loss for a selected service in detail. The report can be run by itself or as a drill-down from a Service Performance Summary (NSP) report.

Note: If the received packet is greater than the transmitted packet, then the packet loss gives a negative value, which is displayed as 0.0.

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 file type, half of the page and only one page’s graph will be displayed.
For Classic Node, there is a possibility of having the same service name with the same service ID but with a different full name multiple times. In such cases, all the services will be listed in the report.

Prerequisites

The following prerequisites are required in order for the report to be generated:

MD SR NE and/or classic NE must be discovered
L2 services/L3 services must exist

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 are created with L2 services.
A TWAMP-Light session must be defined with accounting enabled in either MDM-managed or NFM-P NEs. TWAMP Light sessions are 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.

Table 16-7: Service Performance Details (NSP) report prerequisites for MDM-managed NEs

Monitored object class	Statistics class	Statistics collection	NE types
CFM DMM Session, Site	telemetry:/base/oampm-accounting/cfm-dmm-session-acc-stats	Telemetry statistics	7750 MD-SR

TWL Session, Site	telemetry:/base/oampm-accounting/twl-session-loss-acc-stats	Telemetry statistics	7750 MD-SR

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 a specified service.

Report characteristics

The following table lists the principal report characteristics. It is not mandatory for all service sites to be located within the same region or subregion. If at least one of the service sites falls within the selected region or subregion, the service will be included in the report.
