Perfetto - Platform-wide performance instrumentation and tracing for Android and Chrome

Abstract

Perfetto is the next-generation performance tracing ecosystem for Android and Chrome. This talk will cover the unique challenges that the team needed to overcome to create an integrated solution for their performance tracing needs, ranging from supporting local debugging to analyzing traces from thousands devices in testing labs. The talk will cover:

  • Our library for low-overhead userspace-to-userspace tracing.
  • Integration with Linux kernel's ftrace and /proc interfaces.
  • Trace Processor: a library for ingesting traces exposing them in the form of SQL virtual tables based on a SQLite query engine.
  • The Perfetto UI for visualizing and analyzing traces.
  • Upcoming plans for heap profiling and perf sampling.

Target audience

People who have a sufficient familiarity with ftrace, /proc interfaces, perf sampling and memory profiling.
