Achieving High-Availability with the autonomous agent
To achieve high-availability, specify two SNMP based event destinations when you are configuring the autonomous agent. If you are using SNMP V1 or V2, the trap might not make it to the destination. However, if you are using SNMP V3, a response will be sent to the agent. When specifying a trap destination with SNMP V3, you can use the retries and timeout parameters to assist with high availability. If a notification cannot be properly sent, it will retry for the number of retries specified in the retries parameter. Each retry is attempted after the timeout value is reached. The default number of retries is 3, and the default timeout value is 2 seconds. You can configure these parameters.
If the autonomous agent loses network connectivity, the traps are lost and will not be received by the agent. If you are using hysteresis mode, the pure event traps won't be sent on the next true interval. In the hysteresis mode, the trap is emitted on the first TRUE encountered, and the clearing trap is emitted when reset. The pure events will only be sent on the next true interval if you are in the default rising continuous mode, whereby an alert is sent on each TRUE evaluation of the situation.
