Nagios XI's plans are primarily based on the Node-count of the license. A Node is anything with an IP address or Fully Qualified Domain Name (FQDN) that you would like to monitor (switches, routers, firewalls, workstations, and other network devices). There are no restrictions on the number of Services you can monitor. While paid licenses of Nagios XI do not contain any software-imposed limitations, we have found that systems performing more than 15,000-20,000 checks in a 5-minute interval should consider following our Server Considerations Guide to ensure the best performance on your installation. Nagios XI also offers an Enterprise add-on which enhances the software's capabilities. This addition allows users to schedule reports, project future values with capacity planning, and much more. Refer to our Enterprise documentation or contact a Nagios sales representative to learn more about the capabilities of the Enterprise-level license. With the purchase of a Nagios XI license, you receive access to Premium Features as part of your Maintenance & Support benefits for the first year. After the first year, renewal of your Maintenance & Support plan is required to maintain this feature set. This includes features such as Single-Sign On (SSO) via MS Azure AD, the Nagios Mod-Gearman user interface, and a collection of premium wizards! To learn more and see the full list of features, you can visit our article on Premium Features or contact Nagios sales.
