Chapter 10: Nagios Integration

iv. Install SDT Connector on each client (Section 10.2.4 - Set up clients)
10.2.1 Set up central Nagios server
SDT for Nagios requires a central Nagios server running Nagios 2.x or 3.x. Nagios 1.x is not supported. The Nagios
server software is available for most major distributions of Linux using the standard package management tools. Your
distribution 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 Opengear 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.
10.2.2 Set up distributed Opengear console servers
Each distributed console server must be running firmware 2.4.1 or later. Refer to Chapter 11 for details on upgrading
Opengear firmware.
This section provides a brief walkthrough on configuring a single Opengear console server to monitor the status one
attached network host (a Windows IIS server running HTTP and HTTPS services) and one serially attached device (the
console port of a network router), and to send alerts back to the Nagios server when an Administrator connects to the
router or IIS server.
This walkthrough provides an example, however details of the configuration options are described in the next section. This
walkthrough also assumes the network host and serial devices are already physically connected to the console server.
First step is to set up the Nagios features on the console server:
 Browse the Opengear console server and select System: Nagios on the console server Management Console.
Check Nagios service Enabled
