High Availability
High Availability (HA) solutions for Nagios XI ensure that your Nagios XI server is always up and
running and monitoring your IT infrastructure. The goal of HA is to ensure that if your primary
Nagios XI instance stops or crashes, another instance will automatically and seamlessly take over
the job of monitoring.
This document describes options for achieving High Availability (HA) with Nagios XI.
XI High Availability Options
Monitoring A Nagios XI Server
Nagios administrators often need to ensure that their primary monitoring server is operating properly and can reach the Internet to send alert
notifications via email and other methods. This document describes how to effectively monitor a primary Nagios XI server from an offsite location to
ensure it is both reachable and operating properly.

Migrating From Nagios Core
This guide takes you through the basic steps involved in migrating from an existing Nagios Core
installation to Nagios XI.
Migrating From Nagios Core To Nagios XI
Using The Nagios XI Config Import Prep Tool
Nagios XI includes a configuration file import prep tool designed to pre-process native Nagios Core
configuration files into a format that will be more easily manageable using the XI web configuration
frontend in the future. The import prep tool should be used before importing native Nagios Core configuration
files into the Nagios Core Configuration Manager included in Nagios XI.
This guide shows you how to how to use the Nagios XI configuration file import prep tool.
Using The XI Config Import Prep Tool
Importing Config Files Into XI
Nagios XI includes a configuration import tool which may be used by Nagios admins who wish to import
Nagios Core configuration files into the XI web-based configuration interface. Importing Nagios Core
configuration files is often used when migrating from a pre-existing Nagios Core installation or
installing additional host, service, and command definitions given in third-party examples
(e.g. community addon documentation). This guide shows you how to
import Nagios Core configuration files into Nagios XI for future management via the XI web interface.

SNMP Trap Integration
Integrating SNMP Traps With Nagios XI
SNMP is a powerful and ubiquitous management protocol in most IT infrastructures. SNMP traps are often used by organizations to monitor the
health and status of the network infrastructure. This document takes administrators through the simple steps of integrating SNMP traps with
Nagios XI.
Integrating SNMP Traps With Nagios XI
Sending SNMP Traps With Nagios XI
This document describes how to configure Nagios XI to SNMP traps to other management hosts or network management systems whenever host or
service state changes (alerts) occur. This functionality allows administrators to easily integrate Nagios XI into an environment where multiple
Network Management Systems are used.

Maximizing XI Performance
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.
Maximizing XI Performance
Nagios XI Database Optimization
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.

Passive checks
Configuring Passive Services In Nagios XI
This document describes how to configure passive service checks in Nagios XI. Passive checks are useful when you want to receive and process
data (such as security alerts and log events) from external applications.
Configuring Passive Services In Nagios XI
Monitoring Unconfigured Objects With Nagios XI
Passive check results for hosts and services that are submitted to Nagios by external agents and application using the NSCA or NRDP APIs are not
processed by the monitoring engine until they are configured in Nagios XI. This document describes how to configure monitoring of previously
unconfigured hosts and services that a Nagios XI server has received passive check results for.
Monitoring Unconfigured Objects With Nagios XI
Using NSCA With Nagios XI
This document describes how to enable and use the NSCA addon with Nagios XI. The NSCA addon allows remote Nagios servers and applications to
send passive host and service check results to the Nagios XI server for processing.
Using NSCA With Nagios XI
Exporting the XI Configuration Database
This guide takes you through the process of manually exporting the Nagios XI configuration database and checking for errors that need
resolution. Manual exports are useful when debugging configuration errors - including the failure of XI to apply a new configuration when using
the wizard or the Nagios Core Config Manager.
