Nagious

Introduction
This document describes how you can monitor "private" services and attributes of Windows machines,
such as:
Memory usage
CPU load
Disk usage
Service states
Running processes
etc.
Publicly available services that are provided by Windows machines (HTTP, FTP, POP3, etc.) can be
monitored easily by following the documentation on monitoring publicly available services.
Note: These instructions assume that you’ve installed Nagios according to the quickstart guide.
The sample configuration entries below reference objects that are defined in the sample config files
(commands.cfg, templates.cfg, etc.) that are installed if you follow the quickstart.
Overview
Monitoring private services or attributes of a Windows machine requires that you install an agent on it.
This agent acts as a proxy between the Nagios plugin that does the monitoring and the actual service or
attribute of the Windows machine. Without installing an agent on the Windows box, Nagios would be
unable to monitor private services or attributes of the Windows box.
For this example, we will be installing the NSClient++ addon on the Windows machine and using the
check_nt plugin to communicate with the NSClient++ addon. The check_nt plugin should already be
installed on the Nagios server if you followed the quickstart guide.

Other Windows agents (like NC_Net) could be used instead of NSClient++ if you wish - provided you
change command and service definitions, etc. a bit. For the sake of simplicity I will only cover using the
NSClient++ addon in these instructions.
