Overview

High Availability is an optional module consisting of a group of components that together combine to facilitate the continual monitoring and disaster recovery of NMS sites. The high availability module provides:

• Scripts to perform switchover or failover from an NMS instance at one site (logical grouping of software components and associated hardware that run one or more user applications) to an NMS instance at another site (for instance, Disaster Recovery).

• Continual monitoring of the state of each critical component within each NMS site.

• Disaster recovery from one NMS site to another.

• A comprehensive set of web pages for reporting the state of each site and its components and configuration of the sites being monitored.
