NSP utilization reports overview

General information

NSP utilization reports provide utilization or uptime information at the NE, port, SAP, or LSP level. NSP utilization reports support NEs managed by the NFM-P only, MDM (model-driven Nokia) only, or NFM-P+MDM-mediated NEs.

LAGs are not supported for MDM-only NEs and NFM-P+MDM-mediated NEs except for the Port Throughput Summary (NSP) and Port-LAG Details (NSP) reports.

There is potential for duplication of data in the report inputs when classic NEs are managed in the NSP. If a classic NE is discovered in the NSP with statistics enabled in the NFM-P, the input details are duplicated as both collection schema (NSP) and samdb dictionary tables (NFM-P) will have the entries.

Recommendations

Nokia recommends the following:

  • Generate the reports over multiple pages, as aggregating a high number of pages of a report over a single page could take a considerable amount of time or may even fail.

  • Use the aggregated granularities for generating a report for a higher report range.

  • Track memory utilization in the auxiliary database and manually clear it to ensure that there are no hung queries after the reports are cancelled.

Use cases

Capacity planning—Use the report to examine traffic usage and patterns to plan for capacity requirements.

Limitations

The utilization graph in forecast reports does not stretch when the forecast in the graph is unselected.

Prerequisites

Note: See Supported NEs for information about supported NEs.

  • For Classic (NFM-P)-managed NEs, there are two methods for statistics collection; choose one of the following methods:

    • use the traditional NFM-P SNMP MIB statistics or accounting statistics

    • use MDM to collect gRPC statistics. You must include gRPC in your mediation policy in order to use the policy/discovery rule for classic NEs; see the Device Management Guide.

  • For Model Driven managed NEs, MDM is required to collect gRPC statistics. When MDM is used to collect statistics, persistence must be enabled in the subscription.

  • MDM adapters are required based on the NEs that are managed; contact your technical support representative for more information. You must also enable statistics; see the Data Collection and Analysis Guide.
