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.

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. Imagine if the bandwidth of your HTTP service is suddenly maxed out—how would you quickly analyze which IPs and which requests are causing it? With Kyanos, you just need one command: kyanos stat http --bigresp to find the largest response byte sizes sent to remote IPs and view specific data on request and response metrics.

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.
