Hey, This week I wanted to discover a bit more about how dmesg works under the hood. In the past, I wanted to have alerting based on error messages popping at dmesg, so, maybe by trying to create something that uses the same thing that dmesg uses under the hood, I could better understand it. Also, I knew that in some systems, it was possible to gather the same information from kern.log and that dmesg was all about reading “the kernel ring buffer”, but, what did that mean? More specificall...
