The standard troubleshooting methodology provides a structured and repeatable approach to quick and effective problem resolution. Linux subsystems such as CPU, memory, and boot configurations can be monitored to facilitate troubleshooting. In this course, I will start by describing the standard troubleshooting methodology as a structured approach to problem solving, followed by listing and troubleshooting common CPU and memory problems. I will then manage Linux process CPU time using nice priority values. Finally, I will vertically scale a Linux server by modifying the underlying hardware resources and configuring horizontal scaling with an autoscaling load balancer. This course can be used to prepare for the Linux+ XK0-005 certification exam.
