*Nagios XI is available in multiple different license levels: 100 Node through Unlimited Node. 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.
