Engineering things to work well and the troubleshooting process at a low level are one and the same. It's just that in some cases other people found these bugs and issues before you and fixed them. But this is the cost of OSS, you get awesome stuff for free (as in beer) and are expected to be on the hook for helping with this process. If you don't like it, pay somebody. Really everyone could benefit from learning more about the systems they rely on such as Linux and observability tools like vmstat, etc. The less lucky guesses or cargo culted solutions you use the better.
