Chapter 10: Nagios Integration

10.2 Central management and setting up SDT for Nagios

The Nagios solution has three parts: the Central Nagios server, Distributed Console Servers and the SDT for Nagios software.
Central Nagios server
• A vanilla Nagios 2.x or 3.x installation (typically on a Linux server)
• Generally running on a blade, PC, virtual machine, etc. at a central location
• Runs a web server that displays the Nagios GUI
• Imports configuration from distributed Console Servers
Distributed Console Servers
• B096-016 / B096-048 or B092-016 Console Servers
• Serial and network hosts are attached to each Console Server
• Each runs Nagios plug-ins, NRPE and NSCA add-ons, but not a full Nagios server
Clients
• Typically a client PC, laptop, etc. running Windows, Linux or Mac OS X
• Runs Tripp Lite SDT Connector client software 1.5.0 or later
• Connect to the central Nagios server web UI to view status of monitored hosts and serial devices
• Then use SDT Connector to connect through the distributed Console Servers, to manage monitored hosts and serial
devices

10.2.1 Set up central Nagios server

The Nagios server software is available for most major distributors of Linux using the standard package management tools.
Your distributor will have documentation available on how to install Nagios. This is usually the quickest and simplest way to get
up and running.
Note that you will need the core Nagios server package, and at least one of the NRPE or NSCA add-ons. NSCA is required to
utilize the alerting features of the distributed hosts; installing both NRPE and NSCA is recommended.
You will also require a web server such as Apache to display the Nagios web UI (and this may be installed automatically as a
dependency of the Nagios packages).
Alternatively, you may wish to download the Nagios source code directly from the Nagios website, and build and install the
software from scratch. The Nagios website (http://www.nagios.org) has several Quick Start Guides that walk through this
process.
Once you are able to browse to your Nagios server and see its web UI and the local services it monitors by default, you are
ready to continue.
