View on Flathub ↗

Massif Visualizer is a tool that - who'd guess that - visualizes massif data. You run your application in Valgrind with --tool=massif and then open the generated massif.out.%pid in the visualizer. Gzip or Bzip2 compressed massif files can also be opened transparently.

Features:

  • Interactive chart of memory consumption over time.
  • Detailed snapshot analysis with callgraph visualization (requires KGraphViewer).
  • Summary of peak memory consumption of all allocating functions.
