A framework for the recovery and visualization of system availability scenarios from execution traces

We have proposed a framework to filter, merge, segment, and visualize native log traces. The framework presents the following benefits: (1) it offers analysts the flexibility to specify what to include/exclude from an execution trace, (2) it provides a log segmentation method based on the type of information reported in the execution trace, (3) it uses the UCM language to visually describe availability scenarios at a high level of abstraction, and (4) it offers a scalable solution for the visualization problem through the use of the UCM stub-plug-in concept.
