Datadog integrates with Cilium's observability platform to provide end-to-end visibility into network and Kubernetes environment metrics, enabling users to view service dependencies and traffic flows. The integration allows users to visualize Cilium metrics in Datadog's dashboard, analyze Cilium logs for better insight into performance anomalies, monitor the state of pods with Datadog's Live Container view, observe network traffic with Cloud Network Monitoring and DNS monitoring, and enable custom alerts for unusual log activity. By correlating data from Cilium with Kubernetes resources, users can identify potential issues before they become more serious, troubleshoot problems in their network, and gain a better understanding of their cluster performance.
