This is the approved revision of this page, as well as being the most recent.

Introduction

Nagios is a popular open source monitoring solution that could monitor and report alerts of several components of an IT infrastructure including Windows and of course Linux machines. Basically Nagios can monitor:

  • System resources (e.g. CPU load, disk usage, etc)
  • Network services
  • Environmental parameters (e.g. temperature probes)

In the more general case, Nagios can monitor every piece of collectible information (if a plug-in to collect that information has been written, else it is always possible to write your own plug-ins). The solution can also work on secured links (SSH...) and has a Web interface (V-Shell) through the system administrator can interact if he do not wish to use the command line.
