Frequently Asked Questions

You can use WMI or NSClient++ to monitor internal metrics. First, decide which route will work for you.

WMI works with the built-in management interface that Windows includes, while NSClient++ is an agent that can tap into many different objects. This includes performance counters, WMI, PowerShell, and just about anything you can script out!

As long as your application is returning an exit code and an output, it’s possible.

Follow the troubleshooting steps outlined in Trouble Logging into Web UI.

There are quite a few ways to accomplish this, but there are two primary routes we see customers use.

The first is an agent called NRPE, which you will need to install on each client machine. Once this is completed, you’ll want to run through the Linux wizard to set up checks for monitoring.

The other option is using check_by_ssh, which will use SSH keys to authenticate and run scripts. These scripts will still require the nagios-plugins to be installed if you’re after a certain metric that must be executed on the client machine.

Troubleshoot with this article on crashed database tables.

It can do many things, from sending an email or text notification to opening a case in your external application or executing a remote script that does anything you want. Some customers have it automatically restart a Windows service when Nagios detects problems.

The XI system is comprised of two categories of licensed code:

  1. Open-Source foundation cores and components like Core, PNP, and NDOUtils
  2. The XI UI and system frameworks.

The XI UI and system frameworks are released under a commercial license and contain some code used under license by Nagios Enterprises that cannot be released under an OSS license. Purchasing an XI license grants you a perpetual license to use the XI UI and system frameworks, including the licensed code.
Yes, XI is available free of charge for monitoring small environments. XI installations with a free license can monitor up to seven (7) hosts (nodes) and up to 100 total host and service checks. The free license is self-supported.

Students may qualify for increased or unrestricted monitoring limits based on their needs and qualifications.
Yes, we distribute XI as a virtual machine to ensure you get it up and running quickly.

Manual installation is possible to physical servers running RHEL or CentOS and is available to customers that require it.
Yes, many of our plugins and add-ons can work with either XI or Core and are released under an OSS license.

Because XI uses Core as a monitoring engine, you can use your custom Nagios plugins and event handlers, as well as community add-ons to extend XI’s native functionality.
The initial purchase of any of our commercial solutions includes the first year of license benefits. These benefits allow customers to access version upgrades for one year, submit up to ten support cases, and access the Answer Hub. Optional phone support contracts are available to customers who require additional support services.

XI is our fully supported monitoring solution built on the foundation of Nagios Core with additional features and functionality to streamline your IT management. XI is equipped with time-saving features, including easy-to-use Configuration Wizards, advanced multi-tenancy capabilities, and a customizable GUI.


A step up from the Standard Edition of XI, the Enterprise Edition has all standard features plus additional features, such as capacity planning, bulk modification, and scheduled reports.

The Standard Edition of XI is equipped with time-saving features, including easy-to-use Configuration Wizards, advanced multi-tenancy capabilities, and a customizable GUI. A step up from the Standard Edition of XI, the Enterprise Edition has all standard features plus additional features, such as capacity planning, bulk modification, scheduled reports, and more.

No, a single XI license includes three separate installs:

  • One production install
  • One backup/failover install
  • One testing/development install

This allows for an active-passive failover model, but if you would like to have an active-active setup, then you would need one license for each system. How you engineer the failover is up to you.

XI can directly integrate with Fusion. Log Server and Network Analyzer can integrate with XI.

If you would like to manually migrate your Core instance to XI, follow the guidelines in Migrating from Nagios Core to Nagios XI.
