This section describes HA events.

HA Event

Description
HA_GOING_ACTIVE A standby SD-WAN Edge is taking over as Active because it has not heard a heartbeat from the peer.
HA_STANDBY_ACTIVATED When a new Standby is detected by the Active, the Active tries to activate the Edge by sending this event to the SD-WAN Orchestrator. On a successful response, the Active will sync the configurations and sync data.
HA_FAILED Typically happens after the HA pair has formed and the Active SD-WAN Edge no longer hears from the Standby SD-WAN Edge. For example, if the Standby SD-WAN Edge reboots, you will receive this message.
HA_READY Means the Active SD-WAN Edge now hears from the Standby SD-WAN Edge. Once the Standby SD-WAN Edge comes back up and reestablishes the heartbeat, then you will receive this message.
HA_TERMINATED When the HA configuration is deactivated, and it is successfully applied on the Edges, this Event is generated.
HA_ACTIVATION_FAILURE If the SD-WAN Orchestrator is unable to verify the HA activation, it will generate this Event. Examples include:
  • the SD-WAN Orchestrator is unable to generate a certificate
  • the HA has been deactivated (rare)
