Abstract: 

The explanation for poor performance in a wide-area distributed application is frequently not obvious. Bottlenecks may occur at a host machine or in the network, or in an interaction between the two. The application's environment may also change dynamically during or between runs. Therefore, tools are needed to automatically gather, visualize, and analyze top-to-bottom and end-to-end monitoring information. This lecture presents a monitoring method as well as tools which help instrument and visualize system performance.
