18.2 Application failover basic setup
To deploy the application failover feature, install NNMi on two servers. These two NNMi management servers are referred to in this chapter as the active server and the standby server. During normal operation, only the active server is running network monitoring.
The active and standby NNMi management servers are part of a cluster that monitors a heartbeat signal from both of the NNMi management servers. If the active server fails, resulting in loss of its heartbeat, the standby server becomes the active server.
You can use either of the following methods to configure the application failover feature:
Configuring application failover manually
Configuring application failover with the NNMi Cluster Setup Wizard
