Responsible for Linux infrastructure? Learn to monitor, understand and manage the health and performance of the four core system elements: CPU, memory, storage, and network. Figure out how to spot trouble, pinpoint the cause, and then fix it.

You've probably spent time worrying about the health and welfare of your Linux servers. Wouldn't you love some insight into what’s really going going on under the hood and, more importantly, into setting up a monitoring protocol that will alert you quickly if things seem to be heading south again? In Linux Performance Monitoring and Tuning, you will learn how to identify and manage the way application processes handle CPU, memory, network, and storage resources. You will also learn to use and interpret tools like systemctl, top, iftop, nice, cgroups, and tc, how to monitor the performance of fleets of servers using Collectd, Nagios, and nmon. Finally, you will touch on how to analyze performance trends of those servers with Munin. When you’re finished with this course, you will have a good idea how to optimize process and application performance on Linux systems in a way that will help you improve and foolproof your infrastructure. Software required: Linux. Lots of Linux.
