Introduction

This guide is intended to provide you with simple instructions on how to install Naemon from packages on Ubuntu and have it monitoring your local machine within 10 minutes. No advanced installation options are discussed here - just the basics that will work for 95% of users who want to get started.

These instructions were written for:

  • Debian 9 stretch
  • Debian 8 jessie
  • Debian 7 wheezy
  • Debian 6 squeeze

What You’ll End Up With

If you follow these instructions, here’s what you’ll end up with:

  • Nagios plugins will be installed underneath /usr/lib/naemon/plugins/ (a symlink to /usr/lib/nagios/plugins/)
  • Naemon will be configured to monitor a few aspects of your local system (CPU load, disk usage, etc.)
  • The Naemon web interface will be accessible at http://localhost/naemon/
