About this skill

What it does

The heap-dump-analyzer skill allows you to analyze Java heap dumps to identify memory leaks and performance bottlenecks. It can parse the dump file, identify object allocation patterns, and provide insights into which classes are consuming the most memory. This helps developers understand the root cause of memory issues in their applications.

When to use it

  • Debugging Memory Leaks: Investigate a Java application exhibiting excessive memory consumption or OutOfMemoryErrors.
  • Performance Optimization: Identify large object allocations and potential areas for code optimization related to memory usage.
  • Root Cause Analysis: Determine the specific objects and classes contributing most significantly to heap size.
  • Post-Mortem Debugging: Analyze a heap dump collected after an application crash to understand the state of memory at the time of failure.

Key capabilities

  • Parses Java heap dumps.
  • Identifies object allocation patterns.
  • Reports on classes consuming the most memory.
  • Provides insights into potential memory leaks.

Example prompts

  • "Analyze this heap dump and tell me which objects are taking up the most space."
  • "Can you identify any potential memory leak suspects in this Java heap dump?"
  • “What classes have the highest number of instances in this heap dump?”

Tips & gotchas

  • Requires a valid .hprof file as input.
  • Heap dumps can be very large, so processing may take time and require significant resources.
