New Relic eBPF: Network Metrics

New Relic has introduced eBPF: Network Metrics, a novel network visibility tool currently in preview, designed to address network-layer issues in distributed applications without requiring code changes. This tool leverages eBPF technology to capture detailed TCP and DNS telemetry directly from the Linux kernel and integrates the data into a unified workflow alongside Application Performance Monitoring (APM) and infrastructure data. By providing granular insights into network behaviors such as TCP handshake latency, retransmissions, abnormal closures, and DNS resolution failures, it enables teams to efficiently pinpoint root causes of network issues, reducing downtime and context switching. This solution is particularly beneficial in complex, cloud-native environments like Kubernetes, where it attributes network behavior directly to processes or threads, thus streamlining troubleshooting and enhancing visibility without deploying multiple language-specific tools.
