Enabling Online Trace Analysis

Up to now, TAU and VNG could only provide post-mortem trace analysis. The inherent scalability limitations of this approach due to trace size motivated us to evaluate the extensions and modifications needed to enable online access to trace data. The following discusses the technical details of our proposed online tracing solution.
