Subtrace is the Wireshark for Docker containers, allowing developers to monitor incoming and outgoing requests in their backend server with ease. This tool works seamlessly without requiring any code changes and supports multiple languages. Users can view detailed information like payload, headers, status code, and latency, with minimal performance overhead. Subtrace is built on Clickhouse and is open source, although they are not accepting pull requests at the moment due to being a small startup. However, they are open to feature requests and bug reports. Stay tuned for possible changes in the future.
