Massif Visualizer 0.2

Massif Visualizer is a tool that ???*a*? who'd guess that ???*a*? visualizes massif data. You run your application in Valgrind with --tool=massif and the open the generated massif.out.%pid in this application. You can also compress the log with Gzip or Bzip2 and open it transparently with the visualizer. more???*A*<br /><br />The application consists of three parts:<br />The Overview Chart<br /><br />The first thing you???*a*?ll notice is a nice chart that displays the same as e.g. ms_print does in Ascii-Art: total memory consumption over time.<br /><br />Where Massif-Visualizer goes further is by additionally showing the top ten most cost-intensive locations in your code as a stacked graph below the total cost. The graph also reacts on user-interaction.<br /><br />This view you can use for<br /><br /> * checking whether your application has memory leaks<br /> * finding too expensive peaks<br /> * finding locations that significantly contribute to the overall memory consumption of your application<br /><br />The Snapshot Data Tree<br /><br />Directly next to the above chart, you???*a*?ll see a tree with all of the massif data. The tree items are colored depending on their cost, with red opaque being the most interesting (peak) elements. Green/transparent items are negligible and don???*a*?t add significant cost to your application.<br /><br />You can also search the tree and when you select something in it, the snapshot gets highlighted in the overview chart and the call graph gets updated.<br />The Call Graph for Detailed Snapshots<br /><br />Massif generates a few detailed snapshots that essentially make up the tree. If you want to get an overview in a more comfortable way than the simple tree view, switch over to the detailed snapshot tab and see<br />the tree visualized as a call graph. Zoom in, zoom out, use the birds eye view and see what contributes to a given snapshot. Note that function calls with the same memory cost are grouped to easily find the interesting parts.
