Nagstamon is a Nagios status monitor for the Windows desktop. It resides in systray or as a floating statusbar at the desktop showing a brief summary of critical, warning, unknown, unreachable and down hosts and services and pops up a detailed status overview when moving the mouse pointer over it. Users can react immediately with context menu custom actions.

It is inspired by Nagios Checker for Firefox - I just did not want to have an open Firefox window all the time to monitor our network.

Nagstamon is written in Python so it is highly portable. It has been tested successfully on Ubuntu 8.04 - 14.04, Debian 6 + 7, Fedora 8 - 20, OpenSUSE 11.x, Windows 2000 + XP + XP 64bit + Vista + Windows 7 + 8 + Windows 2008 Server. It works with GNOME, KDE and Windows desktop, in systray, statusbar or fullscreen.

Successfully tested monitor versions include Nagios 1.x/2.x/3.x, Icinga 1.2+, Opsview 3.5+, Centreon 2.1.x, Op5 Monitor 6.3+, Check_MK/Multisite 1.1.10+ and Thruk 1.5.0+.

Using Nagios when it was called Netsaint. Very reliable & using "nagstamon" since 3 months. Found Very stable,but problem is it shows only WARNING/CRITICAL messages,no OK signal with GREEN color. Rest all is fine.

A very nice, neat, tool for keeping an eye on Nagios alerts from a Windows machine.

I have been using this add on for about a month now. This I have to say is one of the most useful add ons I have downloaded. It is easy to use and setup.
