Overview

General information

This chapter provides information about the troubleshooting process, guidelines, and tools, along with a process for troubleshooting a problem in the NSP.

The NSP Troubleshooting Guide is intended for NOC operators and engineers who are responsible for identifying and resolving NSP performance issues. The guide contains troubleshooting information for the following domains:

• managed network

• NSP functions

• NSP platform

• NFM-P platform

Managed network troubleshooting

The NSP has a number of powerful troubleshooting functions and dashboards that help to quickly pinpoint the root cause of network and service management problems to speed resolution.

You can use the NSP alarm and service monitoring functions to help you troubleshoot the network of managed NEs.

Alarms for network objects

The NSP raises alarms against network objects in response to received SNMP traps from managed NEs. You can then use the fault management function to correlate the events and alarms to the managed object, configured services and policies. A correlated event or alarm can cause fault conditions on multiple network objects and services. For example, an alarm raised for a port failure causes alarms on all services that use the port. You can view the alarm notification from the Network Health dashboard.

Platform troubleshooting

You can troubleshoot NSP platform issues that include the following:

• slow system response, poor performance, or excessive disk activity

• database failure, corruption, disk capacity, or performance degradation

• server communication problems, slow response, system alarms or statistics of concern, or inability to manage new devices
