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.*

Challenge
Launch a Script and Monitor the System
- Execute the
systemcheck.shscript from the scripts directory, and send it to the background.- This script will spawn a separate process that will impact the system.
- Use one or more these tools to view active processes to determine what the script is doing.
- Determine what processes are spawned by the script.
- Identify what resources are being impacted by the script.
- Collect the script process ID as well as any related child process PIDs.
- Kill all parent and child processes, preferably using one of these tools.
