Chapter 10 Nagios Integration

Introduction

Nagios is a powerful, highly extensible open source tool for monitoring network hosts and services. The core Nagios software package will typically be installed on a server or virtual server, the central Nagios server.

Console servers operate in conjunction with a central/upstream Nagios server to distribute and monitor attached network hosts and serial devices. They embed the NSCA (Nagios Service Checks Acceptor) and NRPE (Nagios Remote Plug-in Executor) add-ons—this allows them to communicate with the central Nagios server, so you won’t need a dedicated slave Nagios server at remote sites.

The console server products all support basic distributed monitoring. Additionally, the Advanced Console Server (LES1408A, LES1416A, LES1432A, LES1448A, LES1308A, LES1316A, LES1332A, LES1348A,LES1208A-R2, LES1216A-R2, LES1232A, LES1248A-R2) family supports extensive customizable distributed monitoring.

Even if distributed monitoring is not required, the console servers can be deployed locally alongside the Nagios monitoring host server, to provide additional diagnostics and points of access to managed devices.

SDT for Nagios extends the capabilities of the central Nagios server beyond monitoring, enabling it to be used for central management tasks. It incorporates the SDT Connector client, enabling point-and-click access and control of distributed networks of console servers and their attached network and serial hosts, from a central location.

Note If you have an existing Nagios deployment, you may want to use the console server gateways in a distributed monitoring server capacity only. If this case and you are already familiar with Nagios, skip ahead to section 10.3.
