An eBPF-based network issue analysis tool
Features
- Captures network requests such as HTTP, Redis, and MySQL, and helps resolve network problems quickly without complex packet capture and analysis
- Powerful traffic filtering: can filter not only by IP/port but also by process, container, L7 protocol, request/response size, latency, and more
- Advanced analysis: unlike tcpdump, aggregates packet metrics across various dimensions and provides key data for quickly identifying problems
- Kernel-level latency analysis: traces a request's path from the network card to the kernel socket buffer and visually shows the latency at each step
- Lightweight and dependency-free: runs as a single binary file, and all results are displayed on the command line
- Automatic SSL traffic decryption: displays all captured requests and responses in plaintext
