Prepare a Linux Server for Kernel Debugging

The Linux kernel is the core component of the operating system and undoubtedly what makes Linux... Linux. And when there's something wrong with the kernel, the system will end up in an unusable state. You can make things easier when these issues occur by using the tools available at your disposal for monitoring and debugging your kernel. In this lab, you’ll explore two of these tools, `kdump` and `systemtap`. _This lab is not approved or sponsored by Red Hat._
