Course content

5 sections • 14 lectures • 1h 50m total length

  • Introduction1:25

    Just an introduction into what this course is, who I am, and what Sensu is

  • What the heck is Sensu and how does it work?14:55

    Sensu is a monitoring framework. I uses existing open source components and does not re-invent the wheel.

    The plus side to this is that Sensu by itself is easy to understand and simple. The downside to this is that it does put the burden of maintaining the other components on the administrator.

    Here is a list of the components that covered in this video:

    • The Sensu Client (Agent that runs on every host)
    • RabbitMQ (Message queue used between the Sensu Client and Sensu Server)
    • Sensu Server (Picks up messages off the queue and acts on them)
    • Redis (stores persistent state and check history)
    • Sensu API (rest interface)
    • Uchiwa (Sensu dashboard)

    Don't panic. While this initial architectural overview may be a blur, subsequent lectures will go deeper into each component.

  • Why Should I Care About Sensu?13:15

    What makes Sensu special? Why should I even bother investing in a different monitoring system? In this lecture I'll hint at some of the different types of things you can build with Sensu, and explain how such a flexible monitoring framework can really change how you build systems, for the better!

  • Check your understanding of how Sensu really works

Requirements

  • Standard Linux administration knowledge (installing packages, starting things, looking at logs).
  • A VM or Server with a modern OS (Ubuntu is used in this Video) for installing Sensu and testing it out.
  • The server must have access to the internet to download packages and send email.
  • A sense of Curiosity for learning new things!

Description

Sensu is a powerful Next-Generation monitoring framework that is quickly replacing traditional monitoring systems like Zabbix, Icinga, and Nagios.

But diving into a new monitoring system can be difficult without a guide to show you the way! This course can be your guide to understanding how Sensu works and how to deploy it to your infrastructure.

This introductory course will teach you the basics of Sensu's architecture and how to take advantage of the flexibility it provides to build awesome systems.

Contents

  • In-depth architectural overview
  • All videos closed-captioned in English. Hear and See for optimal learning!
  • Step-by-step howto instructions on getting Sensu up and running
  • Leverage your existing Nagios plugins written in C, Python, or Bash
  • Take advantage of the plethora of Open Source Sensu plugins in Ruby!
  • Learn about RabbitMQ, Redis, Ruby Gems, Sensu's API, and more
  • Use Uchiwa, the awesome open source Dashboard for Sensu
  • Setup the foundation to build on more intermediate and advanced Sensu topics

When you are finished with this course you will have setup a complete monitoring solution that actually checks things and actually sends email. This is not a theoretical course, it is a practical one that leaves you with skills and infrastructure to build upon.

Let Me Make The Mistakes For You

It's one thing to read docs and get perfect copy-paste command line examples that work. It is another thing to be in real life watching a real engineer fight a live system and try to get it working! I purposely make mistakes just to demonstrate what happens when things go wrong. That gives me an excuse to troubleshoot the problem and then solve it. Then, when you encounter that same mistake in your infrastructure, you will know exactly what to do!

For Dev and Ops Alike

Sysadmins, Devops Practitioners, Infrastructure engineers, SREs, and simply curious software engineers should take this course to better their craft and learn more about what makes Sensu special. It is not your grandfather's monitoring system. It is a modern, scalable, flexible monitoring system with a great API to integrate with your infrastructure.

Even if you don't end up using Sensu in Production, taking this course will still level-up your monitoring game, by increasing the scope of your DevOps toolbox. So enroll today and check it out!

Who this course is for:

  • *Sysadmins* who are sick of inflexible monitoring systems!
  • Curious *Devopsy* types who have heard of Sensu and would like to try it for themselves!
  • System *engineers* who want to further their craft by adding a super cool tool to their toolbox!
