nagios firefox plugin

This is a very handy Firefox plug-in which places a small, compact statusbar indicator of all warnings and critical events from the Nagios monitoring system. Please ensure you have the latest version of Firefox and download the plug-in below:

Nagios Firefox Plug-in nagioschecker-0.15b1.xpi 162K     [download]

After downloading the .xpi file to your desktop (or location of your preference), drag the file into any firefox window to install the plugin. Once installed, restart Firefox, and then in the extension settings dialog, simply put in our nagios URL (copy & paste from bookmarks ending in nagios/)

This plug-in is great for notifications, and can be extensively configured to filter by event type, severity, and several other factors. In addition, it also includes the default nagios sound alerts which can also be turned off or set to only play for “new” alerts, which I find very helpful to my sanity during an event.

Support for this add-on is provided by the developer at or by sending an e-mail to
