Project description

A description from the repository README:

This repository implements a whole-system, cross-language profiler for Linux via eBPF.

Core features and strengths

• Implements the experimental OTel profiling signal
• Very low CPU and memory overhead (1% CPU and 250MB memory are our upper limits in testing and the agent typically manages to stay way below that)
• Support for native C/C++ executables without the need for DWARF debug information (by leveraging .eh_frame data as described in US11604718B1)
• Support profiling of system libraries without frame pointers and without debug symbols on the host.
• Support for mixed stacktraces between runtimes - stacktraces go from Kernel space through unmodified system libraries all the way into high-level languages.
• Support for native code (C/C++, Rust, Zig, Go, etc. without debug symbols on host)
• Support for a broad set of HLLs (Hotspot JVM, Python, Ruby, PHP, Node.JS, V8, Perl), .NET is in preparation.
• 100% non-intrusive: there's no need to load agents or libraries into the processes that are being profiled.
• No need for any reconfiguration, instrumentation or restarts of HLL interpreters and VMs: the agent supports unwinding each of the supported languages in the default configuration.
• ARM64 support for all unwinders except NodeJS.
• Support for native inline frames, which provide insights into compiler optimizations and offer a higher precision of function call chains.
