Monitoring System Performance Using Multiple Tools

In this hands-on lab, you will be using common commands like `ps` and `top/htop` along with other utilities like `vmstat`, `mpstat`, `iostat`, and `pidstat` to view system performance metrics. Additionally, you will launch a script on the system and then use these tools to locate any processes created by it and monitor system performance. For the final task, you will kill the script process, any child processes, and check system performance again. *This course is not approved or sponsored by Red Hat.*
