What is Nagios?

Nagios is a long standing infrastructure monitoring platform maintained by Nagios Enterprises, based in Saint Paul, Minnesota. Nagios Core is the free, open source monitoring engine that checks the availability of servers, networks, and services and sends alerts when problems occur. Nagios XI is the commercial enterprise edition built on top of Core, adding a web based configuration interface, dashboards, and wizards.

Nagios XI is sold as a perpetual license rather than a subscription, with tiers based on the number of monitored nodes, plus an Enterprise add on for capacity planning and reporting. A free edition of Nagios XI supports up to 7 nodes or 100 services. Nagios also sells Log Server, Network Analyzer, and Fusion as separate licensed products.

Nagios FAQs

Nagios Core, the open source monitoring engine, is completely free. Nagios XI, the commercial enterprise edition, has a free edition limited to 7 nodes or 100 services, with paid tiers above that.

Nagios XI uses perpetual licensing based on the number of monitored nodes, starting at $2,595 for a 100-node Standard license and $4,690 for a 100-node Enterprise license, with the first year of maintenance included.

Nagios Core is the free open source monitoring engine run from configuration files. Nagios XI adds a web based interface, dashboards, configuration wizards, and reporting on top of Core.

Nagios can monitor cloud hosted servers and services, but it is deployed and managed by the user on their own server rather than offered as a hosted SaaS product.

Mod Gearman is a distributed job processing plugin, now officially supported in Nagios XI, that offloads checks from the main server to remote worker nodes for better scalability.
