Want to add Windows host to Nagios? We can help you with it.

Unlike, Unix machines, adding Windows server monitoring is different. To add windows host, we need to install a plugin in the Windows server.

More about Nagios Windows host

Nagios is an open-source software used for monitoring. It supports both Linux and Windows server monitoring.

To add a Windows host to a Nagios Server, we require NSClient++ plugin.

The plugin acts as an intermediate between Nagios and Windows server.

Thus, to add Windows host we install NSClient++ plugin in the Windows first and then make changes in the Nagios configuration file.

Once we download the file, we double-click on the .msi file, to begin with, the installation and click on run.

A Welcome screen appears then we click on Next. Now we check I accept the terms in the License Agreement.

Then we choose Setup type as Typical and click on Next. In the next window, we leave the default settings and click Next.

We edit the file windows.cfg using the command.

vi /usr/local/nagios/etc/objects/windows.cfg

In the configuration file, we enter the details of the Windows server. In host_name, we enter the hostname of the Windows server. Then in the address, we specify the IP address of the Windows server. Once we add the details we save the file.

Next, we open the Nagios configuration file using the command

vi /usr/local/nagios/etc/nagios.cfg

We uncomment the below changes and save the changes.


Now we browse the Nagios GUI. Here, we can see that the Windows host is present on the dashboard.
