+The first session (which occurred last) began by looking at the problem of
+monitoring power usage information for testbeds networks and clouds.  The
+session began with a description of the Cloudlab power monitoring system
+which uses the Intelligent Platform Management Interface (IPMI) to collect
+power measurements over time and make them available to experimenters via a
+web page.  A related talk described the power monitoring service supported by
+the Kwapi system which was designed to offer high frequency data collection,
+allowing users to correlate and associate power measurements with other
+network behaviors (e.g., bandwidth usage). 
+The federation of testbeds presents additional monitoring challenges
+ranging from the complexities of dealing with heterogeneous infrastructure,
+software systems, and data formats, to scalable data collection and
+aggregation, to trust/reliability issues.  Example systems such as
+MODACLOUDS, SPECS, and DICE were described that use monitoring architectures
+consisting of many distinct components, each with a specific purpose, to
+address the complexity of these systems.  The FELIX monitoring service
+handles the scalability challenge by arranging measurement services
+hierarchically at the highest level, but then using a distributed approach
+within testbed islands. The Federated Trust and User Experience framework
+address the problem of assessing a testbed's reliability and trustworthiness
+by combining conventional monitoring information (objective information) with
+reputation-based trust  management systems (subjective information) to
+define a reputation value that can be used to compare testbeds.
+While much work has focused on monitoring testbed infrastructure,
+relatively few tools are available to users to measure their
+specific experiment or slice.  Looking at experimenter mailing lists and
+discussion groups shows that the majority of problems that experimenters
+face would not be detected by monitoring the infrastructure, but rather
+require slice/experiment-specific measurement and validation tools designed to
+test and evaluate the performance of a user's slice or experiment.
