Managing Processes and Tuned Profiles on RHEL 8

A Linux system is a collection of processes, and process management is a critical skill for system administrators. In this hands-on lab, we will examine process management. We will identify CPU/memory intensive processes and will kill those processes. And, we will also examine how to optimize system and process performance by adjusting process scheduling on RHEL 8. The Tuned service is an intelligent application that uses system monitoring to optimize system performance for specific types of workloads. The heart of Tuned are profiles, which are customized for a variety of use cases. In this hands-on lab, we will examine Tuned and how to manage Tuned profiles. **Red Hat Exam Requirements Covered:** - Identify CPU/memory intensive processes and kill processes - Adjust process scheduling - Manage tuning profiles *This course is not approved or sponsored by Red Hat.*
