The tool fbtracert (http://github.com/facebookarchive/fbtracert) was mentioned here recently as a way to get visibility into multi-pathing. Has anyone here ever used this tool successfully? Supposedly Facebook uses this tool internally, but… that doesn’t help much. I’ve tried it on 4 different platforms/OSes (WSL Ubuntu; RedHat; Debian; OpenBSD), and versions of Go (v1.10 through v1.16), in three very different environments (on-prem public IP; on-prem NAT’d; cloud public IP), and I’ve yet to see it produce any meaningful output – each run/iteration/thread only detects one, single, hop out of the entire chain of routers, making it less than useful. Granted, that’s not a full regression test by any means, but if anyone here has ever used it successfully, could you please let me know what sort of environment you ran it in/on?
