Parts of Nagios XI


The major parts (and what they do)

NDOUtils - Data storage and export.

Performance Data - stores performance data for graphs

Agents and Checks - there are a multitude of agents/checks that are used to monitor and check things.


Additionally, because of the openness of Nagios there are many many things that can be added to Nagios to extend the system.  These could be to make the system easier to use, or easier administer, or change the display of data. Many of these are available on the Nagios Exhange (the Nagios Exchange has variety of agents, checks, addons, documents, and more related to Nagios products.)
