In their own words
Nagios XI
Nagios XI monitors servers, network devices, applications and services from a Linux server you manage. It checks configured thresholds, records results and sends notifications. Standard includes more than 90 configuration wizards, auto-discovery, dashboards, performance graphs, an open REST API, automation, configuration rollback and snapshots. Enterprise adds SLA and capacity-planning reports, scheduled reports and pages, business process intelligence, bulk changes and an audit log. Users can be restricted to assigned host and service groups, with authentication options including Active Directory or LDAP over SSL, Microsoft Entra ID single sign-on and Duo two-factor authentication. It is self-hosted on Linux, with virtual machine images for several hypervisors and offline installation on Red Hat and CentOS Stream. A 30-day trial provides unlimited monitoring, Enterprise features and direct support without a credit card. The free plan is limited to 7 nodes or 100 services, whichever comes first. Paid perpetual licenses are priced by monitored nodes: Standard is $2,595.00 once and Enterprise is $4,690.00 once, each shown for 100 nodes.
