Nagwin - Nagios for Windows


Nagwin is a Nagios implementation for Windows systems. It is a packaging of Nagios Core and many other related tools to make it a complete and ready-to-use solution for system monitoring. You can use Nagwin to monitor your IT-infrastructure Nagios-way from Windows.


Nagios is a powerful monitoring system that enables organizations to identify and resolve IT infrastructure problems before they affect critical business processes. Nagios monitors your entire IT infrastructure to ensure systems, applications, services, and business processes are functioning properly. In the event of a failure, Nagios can alert technical staff of the problem, allowing them to begin remediation processes before outages affect business processes, end-users, or customers. Cygwin is a Linux-like environment for Windows. It consists of a DLL (cygwin1.dll), which emulates substantial Linux API functionality, and a collection of tools. Following tools are also a part of Nagwin: Nginx, Php, Perl, Net-SNMP, Pnp4NagiosRRDTool and Blat.

Nagwin comes as a ZIP file containing an installer. Simply unzip your downloaded copy and run the package "Nagios_x.x.x_Installer.exe" :

  1. Accept License agreement.
  2. Specify an installation location.
  3. Specify a service account.
  4. Installation starts. By clicking 'Details' button, you can get more detailed information about installation. Check if everything seems ok.

At the end of the installation, Nagwin gives you some information about how to start. Simply start Nagwin services and point your browser to http://localhost.

Nagwin uses Nginx as web backend with PHP in FastCGI mode. As Nginx doesn't support CGI, a FastCGI wrapper is developed to serve Nagios CGIs.

Nagwin contains standard Nagios Core and should be able to monitor any device as long as you have monitoring plugins for it. Nagwin has already a small set of plugins ready to use in the /plugins directory, and there are a large number of plugins available at Nagios Exchange. However, due to Nagwin's limited environment and Windows, there may be a limited support. You need to try and find out yourself.



By default, Nagwin is configured to monitor your local machine. See following pages for some basic examples. Nagios configuration files are located at etc\nagios directory. Main configuration file nagios.cfg is configured to accept all configuration files in the subdirectory nagwin.  Consult available Nagios documentation to move forward and extend your implementation. In the case there are discrepancies, you can use Nagwin forum available on this site.

For notification purposes, you can use blat, which is installed as a part of the package (see Nagios.cfg for examples).
