Tracy is a real-time performance profiling framework for C and C++ applications. It provides a software instrumentation library that captures high-resolution telemetry data, which is then visualized through a separate graphical interface to identify bottlenecks and resource allocation issues.
The system utilizes a client-server architecture that enables remote profiling, allowing performance data to be captured on a target machine and analyzed on a workstation. It employs lock-free event logging and shared-memory ring buffers to minimize the overhead of data collection, ensuring that the main application logic remains unaffected during execution.
The toolset covers a broad range of observability capabilities, including the tracking of CPU, GPU, and memory activity, as well as the monitoring of synchronization locks and context switches. It supports the correlation of visual frames with performance events and provides symbol-based callstack resolution to map instruction pointers to source code locations.
