Developing Continuous eBPF Profiler - From Kernel to Cloud
Explore the development of a continuous eBPF profiler for extending stack unwinding capabilities in the Linux kernel during this conference talk. Dive into the implementation of features in parca-agent across Arm64 and x86 architectures, addressing scalability and uniformity challenges across compilers and kernel versions. Examine unexpected edge cases encountered while stack walking for different runtimes, compilers, and platforms, focusing on their interactions with DWARF and ELF formats. Investigate the challenges of implementing low-level observability in cloud environments and learn how eBPF can be extended to fetch stacktraces for interpreted runtimes and improve understanding of GitHub CI. Discover the potential of parca-dev for analyzing control flow and optimizing Linux Kernel systems, and contribute feedback on making dynamic continuous profiling more developer-friendly for large codebases.
