NSP and NFM-P troubleshooting tools

NSP troubleshooting tools

NSP provides various functions and dashboards that can help your troubleshoot network, provide various alarm details, and see the network health.

Network Health dashboard

The Network Health dashboard provides a quick view of essential information relating to the proper function of your network. It presents an abbreviated view of equipment and service alarms, root cause alarms, graphical plots of service-affecting network object counts, and network object status.

Troubleshooting dashboard

The Troubleshooting dashboard provides the user with a centralized view of network equipment and service performance. The dashboard allows a network operator to view summarized performance information, and to drill down into specific objects and view performance details, opening objects in NSP functions where necessary. See the NSP User Guide for more information.

Assurance functions

There are assurance and analyze functions used by NSP: fault management, analytics, network and service assurance.

Current Alarms

The alarms management function provides alarm monitoring, correlation, and troubleshooting for the most unhealthy network elements (NE) in the network. You can diagnose problems using various alarm management tools. For customers with NSP in a containerized deployment, see the NSP Network and Service Assurance Guide. For NFM-P-only customers (RPM-only deployment), see the Fault Management Application Help.

Data Collection and Analysis

The analytics function uses business intelligence (BI) software to generate graphical and tabular reports, based on the aggregate statistical data that is extracted from the big data cluster. There are four categories of reports available to you: Network and service, Application assurance, Administration, and NSP. See the NSP Analytics Report Catalog for more information.

Network and service assurance

The network and service assurance functions help you to monitor the health of core, access, transport, and optical NEs and virtual NFs using a combined NE matrix, pre-defined KPIs, alarms, event timeline, and network map. For customers with NSP in a containerized deployment, see the NSP Network and Service Assurance Guide. For NFM-P-only customers (RPM-only deployment), see either the Network Supervision Application Help or the Service Supervision Application Help.

NFM-P troubleshooting tools

The NFM-P supports a number of troubleshooting tools and event logs to help identify the root cause of a network or network management problem.

OAM diagnostics

The NFM-P supports configurable in-band and out-of-band, packet-based OAM diagnostic tools for network troubleshooting and for verifying compliance with SLAs. See STM OAM diagnostics for troubleshooting for more information.

Ethernet CFM diagnostics

Ethernet CFM diagnostic tests detect connectivity failures between pairs of local and remote maintenance end points, or MEPs, in a MEG. Each MEP is a reference point that can initiate or terminate one of the following diagnostic tests:

CFM continuity check CFM loopback CFM link trace CFM Eth test CFM two-way delay

CFM one-way delay CFM single-ended loss (7705 SAR only) CFM two-way SLM

See the NSP NFM-P Classic Management User Guide for more information about Ethernet CFM diagnostic.

RCA audit tool

The NFM-P RCA audit tool allows you to perform on-demand or scheduled verifications of the configuration of services and physical links to identify possible configuration problems. Except for physical links, the NFM-P provides a solution, which, at your request, can automatically be implemented to make all the required configuration changes.

You can perform RCA audits of the following objects:

• VLL services

• VPLSs

• VPRN services

• physical links

• OSPF interfaces, areas, and area sites (NFM-P/CPAM integration only)

• IS-IS interfaces and sites (NFM-P/CPAM integration only)

See the NSP NFM-P Classic Management User Guide for more information about the RCA audit tool.

NFM-P log files

You can use NFM-P log files to help troubleshoot your network. The log files can consume a large amount of disk space during a long period of significant activity. Ensure that the contents of the various log directories are backed up on a regular basis. See the NSP System Administrator Guide for more information about how to perform routine NFM-P system maintenance.

Note: The event log files may be overwritten or removed when you restart an NFM-P server.

NFM-P LogViewer

The NFM-P LogViewer is a system monitoring and troubleshooting utility that parses, formats, and displays the contents of NFM-P log files.

You can use LogViewer to perform the following:

• View and filter real-time log updates.

• View, filter, and sort the entries in a static log view.

• Open compressed or uncompressed log files.

• Compare active logs in real time.

• Automatically send a notification when a specified type of entry is logged.

User activity log

The NFM-P records each NFM-P GUI and OSS user action. The NFM-P User Activity form allows an operator with the appropriate privilege level to list and view the NFM-P GUI and OSS client user activity, and to navigate directly to the object of a user action. You can also open a pre-filtered list of the recent activity for an object from the object properties form.

See the NSP NFM-P Classic Management User Guide for detailed information about the user activity log.
