One Line Summary

Explain User Space Trace (UST) capabilities for application analysis and layout a vision for fully dynamic tracing.

Abstract

This presentation will demonstrate event logging with UST in the context of an multi-threaded embedded application. It will discuss the various costs associated with UST.

The challenges that lie ahead are in supporting fully dynamic tracing with multiple processes having multiple threads. How can we solve the problem of instrumenting code after the fact that we cannot easily change? The talk will walk through the possible solutions to the problem with a emphasis on merging some existing technologies that are already developed or being developed as a part of system tap and uprobes.
