Video description
This course is for the junior-level engineer just getting started with Nagios or the engineer who inherited an existing Nagios infrastructure. You'll explore what Nagios is, how it works, its capabilities, its limitations, and why it remains the premier tool for monitoring servers, networks and apps.
Nagios expert David Josephsen employs a unique storytelling style to walk you through a full-fledged Nagios implementation, starting with 0 systems monitoring and ending with a fully-functional Nagios system operating in a contemporary fortune-500 style network. Along the way, you'll learn about centralized polling theory and execution; scaling; remote execution do's and don’ts; popular and essential Nagios add-ons; and most importantly, why monitoring matters.
- Learn about Nagios and why it remains the premier tool for monitoring servers, networks and apps
