Alerts detection and routing

The alerts detection and routing feature allows you to manage incoming messages containing critical events, such as airbag deployments, crashes, and other emergencies.

In addition to the configured anonymization process, messages are filtered and routed to the special output queues of alert channels.

For example, if a message contains 100 points and 5 events, and one of those events meets the defined alert conditions:

• The entire message is duplicated.
• One copy, without any changes, including an unchanged traceID and extended attributes, is routed to the alert destination queue and is not anonymized.
• The second copy is anonymized per the configured anonymization rules.

HERE Anonymizer Self-Hosted supports two ways of configuring alert detection and routing:

• Simple - for a single alert handling channel.
• Advanced - for multiple alert handling channels.

When you use the advanced configuration with multiple alert handling channels, the message is duplicated the number of times equal to the number of alert conditions met.

This means that if there are three alert channels configured (alertA, alertB, alertC), and a particular message is detected by alert channels alertA and alertC, the message is be duplicated and routed to both output queues of alertA and alertC.

The third instance, a "master copy" of the message is processed according to the configured anonymization rules.

The Alerts detection and routing feature is supported in the streaming mode only.
