Heaptrack
Heaptrack ist ein Heap-Memory-Profiler und Diagnosetool für Anwendungen unter Linux. Es fungiert als Speicherleck-Detektor und Performance-Analysesystem, das Heap-Allokationen und Stack-Traces aufzeichnet, um Speicher-Hotspots und Verbrauchsmuster zu identifizieren.
Das Projekt bietet einen grafischen Heap-Allokations-Visualisierer zur Untersuchung der Speicherauslastung durch Baumansichten und Peak-Memory-Berichte. Es nutzt Flame-Graphs und Allokationsdiagramme, um Speicher-Hotspots zu visualisieren und bei der Erkennung von Lecks zu unterstützen.
Das Toolset enthält Funktionen für das Tracing von Heap-Speicherallokationen und die Generierung von Speicherberichten über Kommandozeilen-Utilities. Diese Utilities erstellen ASCII-Zusammenfassungen der größten Speicherverbraucher und ermöglichen die Konvertierung von Profildaten.
Features
- Memory Profilers - Tracks, analyzes, and visualizes heap allocation patterns and memory usage in Linux applications.
- Heap Profilers - Captures and analyzes memory allocation patterns in the heap to identify leaks and hotspots.
- Memory Profiling - Analyzes memory usage patterns using flame graphs, allocation charts, and tree views.
- Native Stack Unwinders - Provides native stack unwinding to map recorded instruction pointers to function names and source lines.
- State Reconstruction Replay - Reconstructs the application heap state by replaying historical allocation and deallocation logs.
- Memory Allocation Tracers - Monitors and records heap allocation events and stack traces by attaching to running processes.
- Heap Allocation Call Stack Recorders - Records and visualizes full call stacks for every heap allocation to understand memory management.
