Kyanos - eBPF-based Network Analysis & Troubleshooting Tool
Kyanos is an advanced networking analysis tool leveraging eBPF to provide deep insights into packet flow and kernel processing time. It helps efficiently troubleshoot network issues by capturing request/response pairs and visualizing kernel residency.
Project Introduction
Summary
Kyanos is an open-source networking analysis tool built on eBPF technology, designed to offer granular visibility into network traffic and kernel performance to aid in efficient troubleshooting.
Problem Solved
Traditional networking tools often lack the necessary depth to efficiently diagnose complex network issues, particularly those related to packet processing delays within the kernel or scattered application-level communication. Kyanos addresses this by providing low-overhead, kernel-level insights and structured request/response visibility.
Core Features
Packet Kernel Residency Visualization
Visualize the time network packets spend inside the Linux kernel, identifying potential bottlenecks.
Request/Response Capture
Capture and analyze network request/response pairs to understand application-level communication.
eBPF-based Low-Overhead Monitoring
Utilizes eBPF for low-overhead monitoring directly from the kernel.
Tech Stack
Use Cases
Kyanos is valuable in various scenarios requiring deep network visibility and performance analysis.
Scenario One: Pinpointing Kernel Latency
Details
Diagnose application performance issues by visualizing exactly how much time packets spend being processed within the kernel network stack.
User Value
Quickly identify if network performance bottlenecks are occurring before packets even reach the application level.
Scenario Two: Debugging Distributed System Communication
Details
Capture and correlate requests and responses across distributed systems or microservices to debug communication errors or delays.
User Value
Simplify the complex task of tracing network interactions between multiple service components.
