Summary

In this chapter, we learned how to manage processes and monitor our server's resource usage. We began with a look at the ps command, which we can use to view a list of processes that are currently running. We also took a look at managing jobs, as well as killing processes that for one reason or another are misbehaving. We took a look at htop, which is a very handy utility for viewing an overview of our resource utilization. In addition, we learned how to monitor memory usage, schedule jobs with cron, and gained an understanding of load average.

In Chapter 7, Setting Up Network Services, we'll dive back into networking, where we'll learn how to set up our own DHCP and DNS servers for our network, and more. See you there!
