Subtrace is “Wireshark for your Docker containers. It lets developers see all incoming and outgoing requests in their backend server so that they can resolve production issues faster.”
- Works out-of-the-box
- No code changes needed
- Supports all languages (Python + Node + Go + everything else)
- See full payload, headers, status code, and latency
- Less than 100µs performance overhead
- Built on Clickhouse
- Open source
Looks like it outputs to the Chrome Dev Console’s Network tab, or a facsimile of it; “Open the subt.link URL in your browser to watch a live stream of your backend server’s network logs”.
It may be interesting to try this out. (via LWIA)
