Trace Analysis

We are interested in analyzing and visualizing system behavior. In particular, we study visualization and analysis approaches and tools that enable the efficient and effective interactive exploration of system performance traces. We focus on finding approaches and tools for "performance understanding", for example by identifying causal relationships between phenomena to explain the reasons of performance problems.

So far, our efforts have focused on the following two topics:

  • Trace alignment enables reasoning across traces of performance metrics collected in multiple executions.
  • Trace visualization enables the interactive analysis of dynamic system behavior and performance.
