Nagios Enterprise Monitoring Server
Virtual Appliance

NEMS Linux is free to download and use. The virtual appliance however is only available as a perk to those who support NEMS Linux on Patreon (even if only $1 per month). Your ongoing support helps fund the development of NEMS Linux.

Current Version: 1.5

Available Releases

  • NEMS OVA (Open Virtual Appliance)
    Can be easily deployed on virtualization hypervisors such as VMware ESXi, vSphere, Player or Workstation or Oracle VirtualBox. The OVA package contains the entire virtual appliance and is ready to import and boot.

Deployment Notes

  • Before booting, you must configure your virtual Network Interface to use your actual LAN in Bridged mode.
  • While configuring your virtual Network Interface, you must generate a new MAC address for the virtual NIC. Record your virtual MAC address somewhere safe. Do not change your MAC address after initializing NEMS. Doing so would result in your HWID changing, which will disassociate your Virtual Appliance with NEMS Cloud Services.
  • x86 Virtualization must be available and enabled on your physical CPU in order to boot the Virtual Appliance. This is found in your host machine's BIOS/UEFI settings and will be called VT-x (Intel) or AMD-V (AMD), or something similar such as “Virtualization Extensions”.
