If you want to see an excellent way to represent complex concepts graphically, look at the work of Bryce on flickr .This diagram represent, after heavy Gobbledy Gook, the concepts introduced during a project I was leading. I must say that this work really helped communicate all the different objects and concepts.

You can read here Bryce's version of Flickr user model, even better.

I've really appreciated working with you Bryce.

Zenoss published the LISA 06 Survey Results on Open Source Network & Systems Monitoring:

The survey results included responses from over 100 LISA attendees both on paper surveys and via an electronic survey mechanism. Surveys were offered in the Zenoss exhibition booth, at the LISA Birds of a Feather Session: "Solving IT Management Headaches with Open Source Software ".

My main takeaways of this survey are:

• Most pressing issues faced by administrators are monitoring, configuration, Patching & provisioning.
• 65 % of the respondents plan to use OSS tools in the monitoring space and 36% for configuration.
• the most popular tools are Nagios, MRTG/RRDTool, Snort and Nessus, of which none are for configuration management.
