Configuring High Availability Settings

Apr 17, 2014

You can configure two Command Center servers to work as a high availability (HA) pair by configuring one server as primary and the other server as secondary. For more information, see Installing Command Center in High Availability Mode.

Use the HA pair mode of operation to ensure uninterrupted management of network devices by allowing the secondary Command Center server to take over in case the primary server fails, terminates, or shuts down.

To configure high availability settings

  1. On the Administration tab, in the right pane, under Settings, click High Availability Settings.
  2. Under High Availability Details, click Edit and configure the following HA parameters:
    • Heart beat interval: Heartbeats periodically check the availability of an HA node. Specify the interval at which the primary Command Center server must update its health in a database table. The default is 60 seconds.
    • Failover interval: Failover refers to the process of the secondary node taking over when the primary server goes down. Specify the interval at which the secondary Command Center server must check the status of the primary Command Center server in the database. The default is 75 seconds.
    • Retry count: The secondary Command Center server checks the status of the primary Command Center server for failure. Specify the number of times the secondary Command Center server must check the status of the primary Command Center Server before assuming that the primary Command Center server has failed. The default is 1.
    • Backup interval: Specify the interval at which the secondary Command Center server backs up the configuration files from the primary Command Center server.
  3. Click OK.
