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 SASE 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 SASE Orchestrator is unable to verify the HA activation, it will generate this Event. Examples include:
|
VCO_IDENTIFIED_HA_FAILOVER |
Event message reads: Edge HA Failover Detected The SASE Orchestrator has detected that a High Availability failover has occurred on the Edge. |
VCO_IDENTIFIED_HA_FAILURE |
Event message reads: Edge HA Failure Detected The SASE Orchestrator has detected that the Standby Edge has gone down. This event will include the serial number of the Edge. |
HA_UPDATE_FAILOVER_TIME |
Event message reads: Updating HA Failover time from ####ms to ####ms A user changed the failover time for when an HA Edge will failover based on how long the Edge will wait to receive a heartbeat from the Active Edge. Increasing this value can prevent an Active-Active "Split Brain" state for HA Edges under high load. This is done through the HA Failover Detection Time Multiplier located at on the Orchestrator. |
HA_RESET_FAILOVER_TIME |
Event message reads: Updating HA Failover time from ####ms to ####ms When an HA Edge's system has been stable for 60 seconds, the process reduces the failover threshold time by 50%. |
