10.2 Central management and setting up SDT for Nagios
The Opengear Nagios solution has three parts: the Central Nagios server, Distributed Opengear 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 Opengear servers using the SDT for Nagios Configuration Wizard
Distributed Opengear console servers
 Opengear console server running firmware 2.4.1 or later
 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 SDT Connector client software 1.5.0 or later
 Possibly remote to the central Nagios server or distributed console servers (i.e. a road warrior)
 May receive alert emails from the central Nagios server or distributed console servers
 Connects to the central Nagios server web UI to view status of monitored hosts and serial devices
 Uses SDT Connector to connect through the console servers to manage monitored hosts and serial devices
SDT Nagios setup involves the following steps:
i. Install Nagios and the NSCA and NRPE add-ons on the central Nagios server (Section 10.2.1 - Set up central
Nagios server)
ii. Configure each Opengear distributed console server for Nagios monitoring, alerting, and SDT Nagios integration
(Section 10.2.2 - Set up distributed Opengear servers)
iii. Run the SDT for Nagios Configuration Wizard on the central Nagios server (Section 10.2.3 - Set up SDT Nagios
on central Nagios server) and perform any additional configuration tasks
