Installation Options

There are two options available for installing Nagios Fusion:

  1. Use the Nagios Fusion VMware virtual machine. This is the fastest way to get up and running with Nagios Fusion. The VMware machine can also be used in enterprise environments where VMware ESX, vSphere or other VMware server products are deployed.
  2. Install Nagios Fusion manually. Use this option if you wish to install Nagios Fusion on a physical server (e.g. for performance reasons) or a virtual server running a supported Linux distro.
