Nagios XI

Nagios XI is commercial IT infrastructure monitoring software that runs on a Linux server the customer controls. It builds on the open-source Nagios Core engine and adds a web interface, configuration wizards, dashboards, reporting and an API.

Main features

• Checks and thresholds: hosts and services are tested at set intervals and reported as OK, Warning, Critical or Unknown.
• Alerting: contacts are notified of state changes, with escalation and optional scripts that react automatically.
• Agent-based monitoring: the Nagios Cross-Platform Agent covers Linux, Windows, macOS and AIX, alongside NRPE and NSClient++.
• Agentless monitoring: SNMP, WMI, WinRM and SSH checks for devices where no agent is installed.
• Dashboards and wizards: at-a-glance views and guided set-up for new devices, services and applications.
• Integration: several APIs and many community add-ons extend the product.
