Performance statistics

Performance statistics counters record NE data, for example, physical equipment status and routing throughput, for monitoring and troubleshooting. Use the Performance Statistics Search Tool to view device-specific lists of the MIB-based performance statistics that the NFM-P supports.

Performance statistics, except for AA network performance statistics, are collected from NE MIBs using SNMP. The collection can be scheduled, or performed on demand.

You can graphically display performance statistics in real time, or export the data using the XML API. Historical performance statistics can be viewed in tabular or graphical form in the NFM-P client GUI.

Wireless PM counters

The device types that are part of the NFM-P LTE and Small Cell solutions support the collection of performance management statistics, which are called PM counters in the device documentation. The PM counters are collected in PM files, transferred to the NFM-P and stored in the following locations:

PM statistics are not available for display or plotting in the NFM-P GUI; however, the files can be made available to other systems such as the 9959 NPO.

Accounting statistics

Accounting statistics counters typically record service or subscriber usage data for billing or to ensure SLA compliance. Use the Accounting Statistics Search Tool to view device-specific lists of the accounting statistics that the NFM-P supports.

Accounting policies define the schedules that NEs use for the regular collection of accounting statistics. File policies specify how NEs store the accounting statistics data. An NE can perform scheduled accounting statistics collection only when a file policy and an accounting policy are deployed to the NE.

The NFM-P uses FTP or SCP to collect accounting statistics files from NEs. See the device documentation for information about accounting file creation and storage on a device.

You can view historical and real-time accounting statistics in tabular or graphical form in the NFM-P client GUI.

The supported accounting statistics types are:

You can customize the statistics record in a service, subscriber, or AA accounting policy by specifying the counters that are collected and the data thresholds for collection. See the NSP NFM-P Classic Management User Guide for information about creating custom accounting records.

Flow statistics

Flow statistics measure the activity associated with traffic flows. A traffic flow is essentially a series of packets that have the same source address, destination address, and payload type, for example, a specific VoIP or social-networking application.

AA Cflowd statistics

ISA-AA groups support Cflowd sampling and TCP performance data collection for AA applications and application groups. NEs use the IPFIX protocol to send the statistics data in XDR-encoded binary records to one or more NSP Flow Collectors. An NSP Flow Collector can forward the statistics data to an OSS or third-party system for analysis or reporting purposes, and store the data in an NFM-P auxiliary database for use by the NSP Analytics.

See the NSP System Architecture Guide for information about NSP Flow Collector and auxiliary database communication, and the NSP Planning Guide for deployment and scaling guidelines.

The IPDR Reference has comprehensive information about AA Cflowd and AA network performance statistics types and the associated counters.

Server performance statistics

You can collect server performance statistics such as the following from main and auxiliary servers in an NFM-P system:

You can collect server performance statistics on demand, or schedule regular collection using a policy. Server performance statistics can also be collected and graphically displayed in real time, or exported using the XML API. Historical server performance statistics can be viewed in tabular or graphical form in the NFM-P client GUI.
