Real hardware or virtualized

The regify Provider Software Appliance can get installed on real hardware or virtual machines (given it is supported by CentOS6).

Virtualization compatibility:

  • VMWare ESX(i) servers (V5 and newer and vSphere Hypervisor)
  • VMWare Workstation (V5 and newer)
  • Citrix XEN Server V6.2 and V6.5
    • Only supporting Hardware-assisted virtualization (HVM) mode
    • No Paravirtualization (PV) support
  • Parallels Server V6 (Bare Metal)
  • Microsoft Hyper-V (only generation 1, we are currently investigating newer versions)
  • HP Helion
  • OpenStack
  • Amazon Webservices (AWS)
    • Only usable with several serious drawbacks because there is no console access.
    • Therefore we do not offer technical support regarding AWS related questions or problems.

If you plan to install on physical hardware, please make sure that the hardware is fully supported by RedHat/CentOS Linux version 6.

Monitoring support

The regify provider software appliance offers you two kind of monitoring:

The regify provider software appliance gives you access to the standard NAGIOS client plugins. Here is a list of the plugins that are contained (regify provider V4 - 02/2015):

  • nagios-plugins-cluster
  • nagios-plugins-dig
  • nagios-plugins-disk
  • nagios-plugins-dns
  • nagios-plugins-dummy
  • nagios-plugins-file_age
  • nagios-plugins-http
  • nagios-plugins-icmp
  • nagios-plugins-ide_smart
  • nagios-plugins-ifoperstatus
  • nagios-plugins-ifstatus
  • nagios-plugins-linux_raid
  • nagios-plugins-load
  • nagios-plugins-log
  • nagios-plugins-mailq
  • nagios-plugins-memcheck
  • nagios-plugins-mysql
  • nagios-plugins-nrpe-2.14-5.rf.i386
  • nagios-plugins-ntp
  • nagios-plugins-perl
  • nagios-plugins-ping
  • nagios-plugins-procs
  • nagios-plugins-smtp
  • nagios-plugins-ssh
  • nagios-plugins-swap
  • nagios-plugins-tcp
  • nagios-plugins-time
  • nagios-plugins-users

The supported protocol is NRPE.

By default, NAGIOS is disabled but the plugins are available.

There is no GUI support for Nagios, so the usage is for experts only.

Built-in monitoring script

The regify provider software appliance offers a dedicated HTTPS call to get information about the health of the regify provider. By calling this prepared URL, it returns either

  • "OK" 🡆 Everything is fine
  • "WARNING: description" 🡆 System still running, but there are problems
  • "ERROR: description" 🡆 System is in maintenance mode and not running

The description contains detailed information about the reason of the current state.


This monitoring call allows you to generate basic monitoring with no big efforts. This call is testing the following things:

  • Clearing connection health?
  • Is the provider in maintenance mode?
  • Is free disk space bigger than 300MB?
  • Is regibox space available and working (if enabled)?
  • Do we have working cryptography?
  • How is internal database connectivity?
