Nagstamon is a Nagios status monitor for the desktop. It connects to multiple Nagios servers and 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.
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 released under the GPLv2 and free to use and modify.
Nagstamon is written in Python so it is highly portable. It has been tested successfully on Ubuntu 8.04 - 9.04, Centos 5.2, Fedora 8, 9 + 10, OpenSUSE 11.0, Windows 2000 + XP + XP 64bit + Vista + Windows 7 + Windows 2008 Server and OpenSolaris 2009.06.
It works with GNOME, KDE 3.x and Windows desktop.
Successfully tested Nagios versions include 2.x and 3.x.
