Notification Types
EFA notifies the subscribers on the following event or alert types:
- DEVICE_EVENTS - Syslog or RASlog events generated by the devices
- APP_EVENTS - Task or user events that are generated by EFA application
- APP_ALERTS – Alerts that are generated by EFA application. Prior to EFA 3.1.0, alerts were in non-standard or legacy format. EFA-3.1.0 introduces fault-alerts which has more alert specific data.
By default, the subscribers receive all the event or alert types and users have the option to configure the filters during registration of subscribers. The filter option is applicable to both HTTPS and RELP subscribers.

Note
- Existing subscribers (registered in EFA 3.0.0 or earlier) receive all notification alert or event types when upgraded to EFA 3.1.0.
- For modifying the filter values, users must unsubscribe or delete and re-add it. EFA 3.1.0 does not support updating filter value.
- Webhook subscribers receive only fault-alerts introduced in EFA 3.1.0.
- Syslog subscribers receive either legacy alerts or fault-alerts based on the RFC5424 flag.
