LISA14 - Linux Performance Analysis: New Tools and Old Secrets

Linux Performance Analysis: New Tools and Old Secrets

Brendan Gregg, Netflix

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.
