Trace Visualization

Traces are sequences of events or time series of metric values that represent system behavior and performance over time. Visualizing these traces is challenging because of the large number of events (from thousands to millions of events) and the high dimensionality (often hundreds of different event types or performance metrics) of the data.

We are interested in visualization and analysis tools that enable the efficient and effective interactive exploration of such 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.
