**Multi-Cluster Alerting: A Kubernetes-Native Approach**

In this presentation, we will introduce a Kubernetes-native solution for multi-cluster and multi-tenant alerting and notifications which encompasses metrics, events, audits, logs and maintains compatibility with alertmanager.

For metrics, our implementation offers rule groups with different scopes to ensure efficient configuration and compatibility with upstream rule definitions. 

We have also developed specific rule definitions and evaluators (namely rulers) for Kubernetes Events and Audit Events, which share a rule expression engine.

Our notification implementation, known as notification-manager, provides multiple communication channels and routing, filtering, aggregation, and silence through CRDs, and also brings notification history, multi-cluster, and multi-tenant features. These features enable seamless integration across multiple categories of alerting sources and diverse Kubernetes environments.
