I let GPT-4 walk me through troubleshooting steps with my extremely slow read times on my SSD-backed KVM virtual machine. It told me the things it needed, I pasted relevant logs and other output, and finally I solved my issue. I was highly impressed! It parsed atop, top, and various other content, explaining exactly what everything meant. Another benefit was that it was able to present a much more readable version of some of what I pasted. I may have to start using it for cleaning up hard-to-read output (looking at you, atop!) in the future, it really excels at that! Also, the issue ended up being that I that I was reading from what turned out to be an NFS mount. Doh!

Used it recently to try and diagnose a weird networking issue on a server. It got me pretty far, but then the only next steps it could suggest involved installing some software that wasn't pre-installed. I don't like modifying prod servers by hand, especially because we do the whole infrastructure-as-code thing. So I pinged a more senior engineer, they solved it. I asked what they did. They did exactly what GPT-4 had suggested for me to do. (Don't worry we ended up fixing it "properly" afterwards and re-launched the instance). I'm still not going to trust it when it tells me to do something I don't understand on a prod instance, but that was fun to see.
