Aug 09, 2017

You can now configure your SD-WAN appliance to identify alarm conditions based on your network and priorities, generate alerts, and receive notifications via email, syslog or SNMP trap.

An alarm is a configured alert consisting of an event type, a trigger state, a clear state, and a severity.

To configure alarm settings

  1. In the SD-WAN web management interface, navigate to Configuration > Appliance Settings > Logging/Monitoring and click Alarm Options.

  2. Click Add Alarm to add a new alarm. **

  3. Select or enter values for the following fields:

    • Event Type: The SD-WAN appliance can trigger alarms for particular subsystems or objects in the network, these are called event types. The available event types are SERVICE, VIRTUAL_PATH, WANLINK, PATH, DYNAMIC_VIRTUAL_PATH, WAN_LINK_CONGESTION, USAGE_CONGESTION, FAN, POWER_SUPPLY, PROXY_ARP, ETHERNET, DISCOVERED_MTU, GRE_TUNNEL, and IPSEC_TUNNEL.
    • Trigger State: The event state that triggers an alarm for an Event Type. The available Trigger State options depend on the chosen event type.
    • Trigger Duration: The duration in seconds, this determines how quickly the appliance triggers an alarm. Enter ‘0’ to receive immediate alerts or enter a value between 15-7200 seconds.  Alarms are not triggered, if additional events occur on the same object within the Trigger Duration period. Additional alarms are triggered only if an event persists longer than the Trigger Duration period.
    • Clear State: The event state that clears an alarm for an Event Type after the alarm is triggered. The available Clear State options depend on the chosen Trigger State.
    • Clear Duration: The duration in seconds, this determines how long to wait before clearing an alarm.  Enter ‘0’ to immediately clear the alarm or enter a value between 15-7200 seconds. The alarm is not cleared, if another clear state event occurs on the same object within the specified time.
    • Severity: A user-defined field that determines how urgent an alarm is. The severity is displayed in the alerts sent when the alarm is triggered or cleared and in the triggered alarm summary.
    • Email: Alarm trigger and clear alerts for the Event Type is sent via email.
    • Syslog: Alarm trigger and clear alerts for the Event Type is sent via Syslog.
    • SNMP: Alarm trigger and clear alerts for the Event Type is sent via SNMP trap.
