Nagios Log Server

Nagios Log Server is a powerful enterprise-class log monitoring and management application that allows organizations to quickly and easily view, sort, and configure logs from any source on any given network. Log Server is designed to analyze, collect, and store log data based on custom specifications, and provide users with extended insight into the data on their network’s infrastructure.

Nagios Mobile

Nagios Mobile provides a flexible mobile interface for Nagios that works on iPhones, Android phones, and all other portable devices. Nagios mobile comes pre-installed with Nagios XI and can be found on the XI server at the path: /nagiosmobile/

Nagios Network Analyzer

Nagios Network Analyzer is a commercial-grade network flow data analysis solution that provides organizations with extended insight into their IT infrastructure and network traffic. Network Analyzer allows you to be proactive in resolving outages, abnormal behavior, and security threats before they affect critical business processes.

Nagios Reactor

Nagios Reactor is an advanced automation engine designed to save organizations time and money by reacting to problems without human interaction. Reactor allows organizations to rapidly develop, deploy, and manage complex automation tasks in and easy-to-understand manner.

NAT

NAT (Network Address Translation) is a method of using "private" IP addresses on home and office computer networks. NAT allows many computer systems to share a single "public" IP address. Monitoring remote devices/computers behind a NAT (e.g. on another network) can be challenging and may require port forwarding, a persistent VPN connection, or an agent like NCPA.

NCPA

NCPA is a cross-platform monitoring agent for Nagios Core and Nagios XI that runs on Windows, Linux/Unix, and Mac OS/X machines. Its features include both active and passive checks, remote management, and a local monitoring interface. More information on NCPA can be found on Nagios Exchange.

NDOUtils

NDOUtils is an addon for Nagios Core that allows you to export current and historical data from one or more Nagios Core instances to a MySQL database. NDOUtils is included with Nagios XI. More information on NDOUtils can be found on Nagios Exchange.

NetFlow

From Wikipedia: NetFlow is a feature that was introduced on Cisco routers that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow a network administrator can determine things such as the source and destination of traffic, class of service, and the causes of congestion.

Nagios Network Analyzer collects and analyzes NetFlow data to report bandwidth usage and traffic patterns in network activity.

NOC

NOC (Network Operations Center): In large companies or MSPs this is the main /central place where admins monitor the entire network. See also TAC.

NPCD

NPCD or Nagios-Perfdata-C-Daemon is part of an addon for Nagios called PNP4nagios. The NPCP daemon is used to process performance data and place the performance data into RRD files. Nagios XI utilizes the NPCD daemon to process performance data received by the Nagios Core engine.

NRDP

NRDP (Nagios Remote Data Processor) is PHP program designed to be a flexible data transport mechanism and processor for Nagios. It is most often used to submit passive checks to Nagios Core or Nagios XI from a remote Linux or UNIX machine. It uses standard ports protocols (HTTP(S) and XML) and can be implemented as a replacement for NSCA. NRDP is available from Nagios Exchange.

NRDS

NRDS is a component pre-installed on a Nagios XI server that allows the administrator to create and manage configurations and plugins to be deployed with a passive agent that can be installed on a variety of operating systems including Windows, Linux, AIX & Solaris. The passive agents downloads the current configuration and the required plugin from the Nagios XI server and run the checks and posting the results to the XI server.

NRPE

NRPE (Nagios Remote Plugin Executor) is an addon allows you to remotely execute Nagios plugins on remote Linux/Unix machines. This allows you to monitor remote machine metrics (disk usage, CPU load, etc.). NRPE can also communicate with some Windows agent addons like NSClient++, so you can execute scripts and check metrics on remote Windows machines as well. More information on NRPE can be found on Nagios Exchange.

NSCA

NSCA is an addon written in C that allows you to send passive check results to Nagios Core and Nagios XI. The NSCA addon consists of a daemon that runs on the Nagios system and accepts passive checks from remote send_nsca client scripts. More information on NSCA can be found on Nagios Exchange.

NSClient++

A Windows agent for Nagios that allows users to monitor metrics (disk, CPU. and memory usage), service states, and more using Nagios, XI supports the NSCIient++ addon and uses it to monitor Windows machines. Many users prefer NCPA over NSClient++ for monitoring Windows machines.
