Linux Performance Analysis: New Tools and Old Secrets
LISA: Where systems engineering and operations professionals share real-world knowledge about designing, building, and maintaining the critical systems of our interconnected world.
The LISA conference has long served as the annual vendor-neutral meeting place for the wider system administration community. The LISA14 program recognized the overlap and differences between traditional and modern IT operations and engineering, and developed a highly-curated program around 5 key topics: Systems Engineering, Security, Culture, DevOps, and Monitoring/Metrics. The program included 22 half- and full-day training sessions; 10 workshops; and a conference program consisting of 50 invited talks, panels, refereed paper presentations, and mini-tutorials.

At Netflix, performance is crucial and we use many high to low level tools to analyze our stack in different ways. In this talk, I will introduce new system observability tools we are using at Netflix, which I've ported from my DTraceToolkit, and are intended for our Linux 3.2 cloud instances. These show that Linux can do more than you may think, by using creative hacks and workarounds with existing kernel features (ftrace, perf_events). While these are solving issues on current versions of Linux, I'll also briefly summarize the future in this space: eBPF, ktap, SystemTap, sysdig, etc.

Brendan Gregg is a senior performance architect at Netflix, where he does large scale computer performance design, analysis, and tuning. He is the author of the book "Systems Performance", and recipient of the USENIX 2013 LISA Award for Outstanding Achievement in System Administration. Previously a performance and kernel engineer, his recent work includes developing visualizations and methodologies for performance analysis, and tools which are included in multiple operating systems.
