Datadog Network Performance Monitoring is an automated tool that provides instant visibility into the topology of your Istio-managed network, allowing you to identify dependencies between services, pods, and containers. It helps dev and ops teams ensure that their Istio network infrastructure is healthy, performant, and routing traffic as intended. The tool automatically visualizes network performance metrics, such as volume, errors, and latency, and provides context on issues related to Istio's control plane and applications running in the mesh. By leveraging Datadog Network Performance Monitoring, teams can root out inefficiencies and misconfigurations, identify network errors and latency, pinpoint Envoy-related performance degradations, and get the context they need to locate issues between the Istio control plane and applications it manages.
