This document is intended to describe where Nagios® XI™ and its related components are located on the machine where Nagios XI has been installed. The Nagios XI directory structure is slightly different from the Nagios Core directory structure and it is important to understand the differences. Is is also important if you want to customize your Nagios XI installation.
This document is intended for use by Nagios XI Administrators who wish to better understand or customize their XI installation.
This document describes the Nagios Core, Nagios XI, and system logs on a Nagios XI server, including the locations and a brief descriptions of their potential contents and diagnostic uses.
This document is intended for use by Nagios XI Administrators who want to have a better understanding of the logging architecture in Nagios XI and wish to diagnose potential Nagios XI issues with or without the help of Nagios Support.
Need a bigger Nagios XI VM? This guide takes you through the steps required to increase the size of your Nagios XI VMware virtual machine.
Users who with to run the Nagios XI virtual machine under Sun's VirtualBox instead of VMware can do so by following this guide written by Tony Yarusso.
The purpose of this documentation is to provide a guide on importing the Nagios XI virtual machine into a Microsoft Hyper-V environment.
This guide is directed towards Microsoft and Nagios administrators interested in running the Nagios XI virtual machine within a Microsoft Hyper-V hypervisor environment.
This document describes how to backup a Nagios XI installation and restore an XI installation from a previously made backup. Backups are an important aspect of administration and maintenance, and can easily facilitate the migration of a XI installation between a virtual server and physical server and the design of a failover or disaster recovery instance of XI.

This document is meant to show a step-by-step guide for offloading the NDO2DB daemon from the central Nagios XI server to an external, remote server. NDO2DB is an acronym of “Nagios Data Output To Database” and is a component of NDOUtils. Offloading NDO2B allows the processing of NDO to be offloaded to a server separate to your Nagios XI server.
This document is intended for use by Nagios Administrators who wish to offload NDO2DB.
Offloading NDO2DB To Remote Server
This document describes how to maximize the performance of your Nagios XI server in a non-distributed environment. This document will discuss maximizing active checks on a single Nagios XI server, and is intended for Administrators using primarily active checks.
Nagios XI stores current and historical information in various databases in order to facilitate reports and provide users with instant information on monitored elements. Over time the Nagios XI database tables may grow to excessive size, resulting in poor performance and high disk space and disk I/O utilization. This document describes how to configure optimal database settings for Nagios XI.
Nagios XI Database Optimization
This document describes how to enable rrdcached with Nagios XI as a step to improve performance and reduce disk I/O on large installations. rrdcached is a daemon that receives updates to existing RRD files, accumulates them and, if enough have been received or a defined time has passed, writes the updates to the RRD file.
This document describes how to repair the database used by Nagios XI.
Repairing The Nagios XI DatabaseThis document describes how to configure optimal database settings for Nagios® XI™ for increased performance. Nagios XI stores current and historical information in various databases in order to facilitate reports and provide users with instant information on monitored elements. Over time the Nagios XI database tables may grow to excessive size, resulting in poor performance and high disk space and disk I/O utilization.
Nagios XI Database OptimizationManaging a Nagios XI server is an important requirement to ensure that the monitoring server can be configured to meet organizational needs and that application updates (patches and upgrades) can be applied. Nagios XI servers that are placed on remote networks often requires that an administrator configures firewalls and routers to allow access to management features. This document describes the requirements for and methods of managing remote Nagios XI servers.
Managing Remote Nagios XI ServersThe purpose of this document is to provide a guide on changing the default passwords for an existing Nagios XI installation to ensure a safe and secure monitoring environment. This includes changing the passwords for the Linux root user, and users the Nagios XI software uses to access the MySQL and Postgres databases.
This guide is directed towards Nagios XI administrators interested in changing the default passwords for the local root account, MySQL accounts, and Postgres accounts for a secure Nagios monitoring server.
