LinuxCon 2010: Efficient Trace Format for System-Wide Tracing

This talk presents the steps taken to move towards a consensus about a trace model and format to gather system-wide traces in a way that respects the embedded, telecommunication and high-performance computing industry requirements. It presents some use-cases gathered from the industry, the requirements imposed by the embedded, telecommunication, and high-performance computing Linux users and discusses the reaction of the kernel community towards these requirements. It finally presents a trace format proposal that aims at fulfilling these requirements.

LinuxCon 2010 Tracing Mini-Summit: A new unified Lockless Ring Buffer library for efficient kernel tracing

The Lockless Ring Buffer library is proposed as a response to both Linux community unification and industry high-performance requirements. This is a major step in tracer infrastructure unification, providing flexibility, high-throughput, reliability and real-time awareness to both tracers and kernel drivers through a simple API.

LFCS2010: LTTng, State of the Union

This presentation will discuss the latest additions done to the LTTng project: the UST user-space tracer, the Eclipse Linux Tools Project LTTng integration, and user-space static tracepoints integration with gdb. An update on the latest LTTng roadmap will also be presented. The LTTng move from GPLv2 to dual LGPLv2.1/GPLv2 licensing will be explained.

ELC2010: Using the LTTng Tracer for System-wide Performance Analysis and Debugging (Hands-On Tutorial)

This session is a hands-on tutorial on how to use the LTTng tracer. It presents the steps required to record a trace in the various operation modes of the tracer. The performance overhead trade-offs will be discussed. Navigation in a trace with the LTTV trace analyzer, including tips and tricks on how to best use the LTTV plugins will be demonstrated.
