KubeTracer is a high-performance, cloud-native network monitor designed for transparent visibility into HTTP/gRPC traffic across Kubernetes nodes. Unlike proxy-based service meshes, KubeTracer operates with zero sidecars, requires no application restarts, and ensures near-zero overhead on your application pods.
By tapping the host network interface, KubeTracer reconstructs TCP streams and logs live traffic—useful for debugging distributed systems and monitoring inter-service communication.
