Low-Overhead, Zero-Instrumentation, Continuous Profiling for OpenTelemetry - Christos Kalkanis

Low-Overhead, Zero-Instrumentation, Continuous Profiling for OpenTelemetry - Christos Kalkanis, Elastic Elastic has recently donated its whole-system continuous profiling agent to OpenTelemetry. After a thorough community review process, the donation was enthusiastically accepted. Leveraging eBPF, the profiling agent provides unprecedented visibility into the runtime behavior of all applications: it builds stacktraces that go from the kernel to userspace native code, all the way into code running into higher level runtimes, enabling users to identify performance regressions, reduce wasteful computations, and debug complex issues faster. This session will explore: - Benefits of eBPF-based continuous profiling compared to conventional approaches that rely on application instrumentation - How the agent builds profiles that seamlessly span kernel, native code and most widely used application runtimes - Integration with the rest of OpenTelemetry: OTLP and Collector
