In my previous article, I demonstrated how easy it is to passively monitor Linux machines with Nagios Remote Data Sender (NRDS) and Nagios XI. In today’s article, I will cover passive monitoring of Windows machines via NRDS.
Monitoring Windows machines via NRDS is no different than monitoring Linux boxes. You need to follow the same three steps:
- Adding Configuration
- Client Installation
- Configuring the host and its services
Step 1 – Adding Configuration
Go to Admin -> Monitoring Config -> NRDS Config Manager, click on Create Config, select Windows (32- or 64-bit) from the Operating System drop-down menu, and click on the Next button. You will see the Edit NRDS Config page. Most of the config options will already be populated for you with the default options. All you will need to do is type a config name, select a token from the drop-down menu, and click on the Apply button. For this example, we will be creating a config called “Win7x64”.

When active agent-based monitoring is not an option (because of a firewall, or security restriction), passive monitoring can provide the solution necessary to maintain network security and health. Today we will be discussing Nagios Remote Data Sender (NRDS) and how it can monitor Linux machines using passive check results. Passive results are sent to the Nagios Remote Data Processor (NRDP) server and processed in Nagios XI.
The NRDS client configuration can be managed centrally via the NRDS Config Manager Component in Nagios XI. Updated configuration files on the NRDS server are automatically picked up by all clients. The NRDS client runs on a cron job at a specified interval. Each time it runs, it will do the following:
- Run all of the commands, specified in the config file
- Send the results back to the Nagios XI server
- Check if there is a new version of the configuration file on the Nagios XI server, and if there is one, it will download it
- Download all of the plugins it needs from the server and install them on the client
In this article, I will show you how you can start monitoring a Linux host passively in three easy steps.
Step 1 – Adding Configuration
Go to Admin -> Monitoring Config -> NRDS Config Manager, click on Create Config, and select Linux from the Operating System drop-down menu.

The Latest version of the NRDS Config Manager (version 1.3) is now available!
NRDS Config Manager allows you to centrally define configuration files and plugins for monitoring agents. This centralized configuration tool makes the configuration of monitoring agents easy and flexible.
The latest version contains major bug fixes to both NRDS_Win and NRDS_Lin agents. There are also a number of new enhancements, including improved SSL support, an extension handler for common script types, and the ability to build your NRDS_Win installer files on the fly.
Documentation on latest NRDS_Win capabilities can be viewed at:
To install the latest version, simply go to the “Admin” menu of Nagios XI and Choose “Manage Components”. Lastly choose “Check for updates” and you will be notified of the latest updates for all components!
