Uprofiler
Uprofiler is a cross-language performance profiling tool designed to help developers understand the runtime behavior of software applications. It collects CPU sampling data, memory allocation information, and I/O activity, and presents findings through flame graphs, call trees, and dashboards. The project emphasizes low overhead and interpretability, making it suitable for use during development and in production when profiling is safe.
Architecture and data flow: Uprofiler uses a lightweight in-process agent that instruments or samples code, a
Language and platform support: The tool provides language bindings or adapters for common languages such as
Core features: CPU profiling with call graphs, memory profiling with allocation and lifetime tracking, thread and
Usage model: Developers install the profiling agent in their application, configure the profiling scope and duration,
History and governance: Uprofiler is maintained by an open-source community and hosted on a public repository.
