Bytehound
Bytehound is a Linux memory profiler that utilizes a custom global allocator to intercept memory requests and track allocations and deallocations. It records full call-stack traces for every memory operation to map allocations back to their originating source code.
The project features a remote memory profiling system that streams capture data via network sockets to a separate machine, minimizing resource overhead on the target system. Analysis is supported by a specialized domain-specific query language used to automate the detection of memory patterns and anomalies.
The tool covers heap allocation analysis to identify leaks and fragmentation, as well as runtime introspection for monitoring and tuning allocator states. Data can be exported and rendered through a web-based visualizer to provide graphical representations of memory usage and allocation patterns.
