Linux Plumbers Conference: Scaling Micro-conference

The Linux Plumbers scaling micro-conference focus on scaling both upwards (many cores) and downwards (low footprint, energy efficiency) at all layers of the software stack. Our intent is to bring together application, libraries and kernel developers to discuss the scalability issues they currently face, and get exposure for the ongoing work on scalability infrastructure. It was held in August 29-31, in San Diego, California.

Tracing Summit 2012: Interoperability Between Tracing Tools with the Common Trace Format (CTF)

This presentation (available as PDF) introduces new technologies and a common format allowing tracing of Linux systems at the software (hypervisor, kernel, user-space), and hardware levels. One major building block of CTF is the Trace Stream Description Language (TSDL) which flexibility enables

LinuxCon North America 2012: LTTng 2.0: Tracing, Analysis and Views for Performance and Debugging

This presentation is available as PDF.

LTTng 2.0 can be used with various tools which help digging through large amount of trace data, from high-level perspectives down to the details. This presentation will focus on the usability of LTTng, showing how the combined user-space and kernel tracers, high-level summary views such as LTTngTop, graphical analysis tools such as the Eclipse Linux Tools LTTng plugin, can be used to solve hard software problems.

Linux End User Summit 2012: LTTng 2.0: Kernel and Application Tracing for the Enterprise

Presentation slides.

The newly available LTTng 2.0 kernel and user-space tracer offers a unified user interface tailored to the industry needs. It enables holistic tracing of live production systems across the kernel and user-space execution layers, while adding only a small overhead footprint. It is easy to install, uses most of the instrumentation sources present in mainline and distribution Linux kernels, and provides mechanisms for user-space instrumentation. This presentation covers the various features offered by LTTng 2.0. The target audience includes people responsible for maintenance, deployment or development of mission-critical, performance-sensitive, and/or latency-sensitive production systems running on GNU/Linux.

LinuxCon Europe 2011: LTTng 2.0 : Application, Library and Kernel tracing within your Linux distribution.

This presentation (available as PDF) introduces LTTng 2.0, detailing its new features. Amongst these, the most welcome are be the ability to use it on vanilla and distribution kernels, as well as the ability to hook on Tracepoints, Kprobes, Ftrace function tracing and Perf PMU counters. The new integrated command line interface for both the kernel and user-space tracers (LTTng and UST) will be presented. The new Common Trace Format (CTF) natively produced by LTTng 2.0 will be described.
