This document outlines how alerts are dispatched to channels and sent as notifications.
Channel dispatch
When the notification system receives an alert collection, it dispatches alerts to different channels based on their attributes.
- Example 1: Critical alerts are sent via DingTalk, while all other alerts are sent by email.
- Example 2: An alert with the tag sensitive=p1 triggers both an SMS notification and an email to the security team.
Batched sending
After the system receives an alert collection, it sends the entire collection to a specified channel.
For example, if you group alerts by the service dimension, the system combines alerts from the same service (e.g., service1) into an alert collection and sends it as a single notification within a specified time frame.
