Notification Types
    
    
        XCO 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
                generated by XCO
- APP_ALERTS – Alerts are generated by
                    XCO. 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.
- APP_ALARMS – Alarms are generated by
                    XCO.
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.
