Chapter 3 : Monitoring

Back to Course Introduction

This the previous chapters, we have spent quite a bit of time understanding operating systems and command line and why it's so important.
Modern cloud and IT tends to hide or abstract a lot of how servers and operating systems function as well as how they are monitored.
This means engineers often lack the knowledge and expertise on how to dismantle a system and monitor it with bare essential command line tools.

In this chapter we'll take a look at monitoring concepts and introduce a few more command line tools that help us monitor our server.
