Over the past week I have been flexing my monitoring skills again. Of course the landscape has changed since I worked on this a few years ago. Today, I am struggling with a commercial product, unnamed. Bloated, expensive, horrible GUI, and time consuming. I am sure it is a good product given that you have an entire staff dedicated to managing it.
So, I went back to my roots and set up an Icinga instance. I have it fully working on a Linux box monitoring Windows hosts. Agentless. No more nsclient installs. I am using check_wmi_plus plugin for everything Windows. You can supply a wmi query string to the plugin for anything WMI. Here are some URLs:

some service definitions:

I am also monitoring out Java infrastructure. You need to make sure the java app is set up for remote jmx monitoring before this will work.

and some nice service defs and commands:

Maybe I will get some time to write up a comprehensive faq.
