Artemis is a framework designed to analyze logs for performance troubleshooting. It is formed by 4 parts: log collection and data extraction, database, visualization tool and plug-in interface.

I liked that the paper presents a real problem that was detected using this tool. After reading the paper, I am not sure how much work is required to adapt Artemis to a new environment/application versus writing a quick-and-dirty application specific script to monitor interesting variables.
I think a tradeoff here is the log structuring to push more in the automated part of the analyzer and make analysis easier vs the ease of generating (unstructured) logs.
Related to this, the paper does not specify how the DryadLINQ computation that summarizes the logs works, and how does this always scale to use a commercial database for the analyzed data.
