Linux tracing with LTTng - The love of development without printf() - FOSDEM 2014

This presentation is available as PDF.

Presenter: David Goulet, EfficiOS

In the past, a lot of effort has been invested in high performance kernel tracing tools, but now the focus of the tracing community seems to be shifting over to efficient user space application tracing. By providing joint kernel and user space tracing, developers now have deeper insights into their applications. Furthermore, system administrators can now put in place a new way to monitor and debug systems using a low intrusiveness tracing system, LTTng.

This presentation explains how LTTng can be used as a powerful development and debugging tool for user space applications taking advantage of this year's exciting new features such as network streaming and snapshots. It demonstrates how open source developers and hackers can use LTTng kernel and user space tracers to create powerful logging systems and easier debugging, thus greatly improving development and maintainability of their project(s).

Finally, this talk concludes with the future work we will be doing on LTTng, and how the community can help with improving the project from feedback to very valuable contributions.
