Kyanos is an eBPF-based network issue analysis tool that enables you to capture network requests, such as HTTP, Redis, and MySQL requests.
It also helps you analyze abnormal network issues and quickly troubleshooting without the complex steps of packet capturing, downloading, and analysis.
This is free and open source software.
Features include:
- Powerful Traffic Filtering: Not only can filter based on traditional IP/port information, can also filter by process/container, L7 protocol information, request/response byte size, latency, and more.
- Advanced Analysis Capabilities : Unlike tcpdump, which only provides fine-grained packet capture, Kyanos supports aggregating captured packet metrics across various dimensions, quickly providing the critical data most useful for troubleshooting.
- In-Depth Kernel-Level Latency Details: In real-world, slow queries to remote services like Redis can be challenging to diagnose precisely. Kyanos provides kernel trace points from the arrival of requests/responses at the network card to the kernel socket buffer, displaying these details in a visual format. This allows you to identify exactly which stage is causing delays.
- Lightweight and Dependency-Free: Almost zero dependencies—just a single binary file and one command, with all results displayed in the command line.
- Automatic SSL Traffic Decryption : All captured requests and responses are presented in plaintext.
