How to Passively Monitor Windows Machines with NRDS & Nagios XI

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:

  1. Adding Configuration
  2. Client Installation
  3. 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”.

Monitoring a Windows Machine with Nagios XI & NCPA

We have recently developed a cross-platform monitoring agent called NCPA that is designed to simplify the monitoring of devices with a wide variety of operating systems. NCPA can be used as a passive or active agent and monitors a multitude of different metrics right out of the box. In this article I will show you how easy it is to monitor a Windows machine with Nagios XI and NCPA. To do this, simply follow these 3 easy steps:

Step 1 – Installing and configuring NCPA on the remote box.

The NCPA installer can be downloaded here: NCPA’s Installer Direct Download. Instructions on installing NCPA can be found here: NCPA Installations Instructions. Download it on the Windows machine that you want to monitor and run the installer.

In this example, we will be using NCPA as an active agent.  This is the quickest and easiest way to begin monitoring with NCPA.  The image below is what the installation GUI looks like on the Windows device that you’re monitoring.  To use NCPA as an active agent, all you have to do is enter a token.  This token will be used to authenticate the connection between the Nagios XI server and the monitored device later in the article, so it’s important to choose a token you will remember. For this example, we entered “welcome“.  Click Next to finish the installation.

Major Improvements to Agent-Based Monitoring with the Release of Nagios Cross-Platform Agent — NCPA

Major improvements to agent-based monitoring have been taking place at Nagios Enterprises. NCPA, the Nagios Cross-Platform Agent, is a project that has the potential to revolutionize agent-based monitoring and increase the efficiency of IT support teams world-wide.

As many Nagios users know, monitoring with agents means juggling the installation of many different types of plugins to try and match devices, operating systems, and the basic functions of each agent. For example, in a simple agent-based Linux and Windows server environment you have to install 2 agents, know the 2 user manuals, there are 2 times the troubleshooting hours required, 2 times the commands on remote systems, 2 change logs to sift through for potential update breaks…the list goes on. It can be very difficult to keep organized and take a lot of time to implement and update your configuration, especially when your monitoring environment becomes larger and more complex.

Whether your environment is large or small, there are usually a myriad of devices that need to be monitored and more often than not, some sort of agent needs to be installed on these devices.

Wouldn’t it be simple if you only had to install one agent regardless of operating system or device?

We have been working on a project that aims to do this. Nagios Cross-Platform Agent (NCPA) is a fully contained agent that runs on Mac OS X, Windows, and Linux and seeks to solve all of the previously mentioned pitfalls of agent based monitoring with Nagios. The main goal of NCPA was to monitor the core metrics of a server and other devices without the added hassle of plugins and dependencies. Metrics such as CPU Usage, Disk Usage, Memory Usage, Interface Usage, Swap Usage, User Count, etc. are preloaded in NCPA so that all you have to do is install the agent. It has since broadened in scope to be a general purpose agent that is very good at doing the aforementioned job. Just install the NCPA agent on your system, and away you go.

Features & Benefits of NCPA:

-Installs on multiple platforms : Windows, Linux, Mac OS X and FreeBSD (untested on AIX, HPUX and Solaris)
-Real-time performance graphs and GUI configuration
-Fully contained agent, including dependencies
-Identical cross-platform configuration editing for both active and passive agents
-Minimizes knowledge needed to know down to one
-Advanced visual data representation

Direct links to the NCPA .exe and .rpm files can be found in the installation instructions which can be downloaded at the link below: Installing NCPA.pdf

We are very excited about this new agent and are currently looking for real world testers to try it out. To test NCPA please contact nscott@nagios.com. Thanks!

NRPE 2.15 Released – Now with IPv6 Support

NRPE 2.15 was released earlier today. The primary update in this version of NRPE is full support for IPv6.

The NRPE daemon now has the ability to listen on IPv4 and/or IPv6 addresses. In addition, the check_nrpe plugin now accepts switches that specify whether an IPv4 or IPv6 connection should be made to the NRPE daemon. The NRPE daemon has always had the ability to perform checks using IPv6, assuming the plugin it runs supports it. Thanks to Leo Baltus for the patch that made this possible.

IPv6 communication has been tested on Linux (RHEL/CentOS) and is known to work there. It also known to compile on other Unices that we have access to: Solaris 10, AIX 5.3 and 6.1 and HP-UX 11i v1. Feedback on these and other platforms is welcome. Bugs or enhancements (preferably with patches) can be submitted to http://tracker.nagios.org. Other discussion/questions can be sent to the mailing lists or http://support.nagios.com/forum.
