       massif-visualizer - visualizer for Valgrind Massif memory-usage tracking tool


       massif-visualizer [massif-data-file]


       Massif  Visualizer  is  a  tool  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.

       The application consists of three parts:

       The Overview Chart

       The  first  thing  you'll  notice is a nice chart that displays the same as e.g.  ms_print
       does in Ascii-Art: total memory consumption over time.

       Massif-Visualizer goes beyond that by additionally showing  the  top  most  cost-intensive
       locations  in your code as a stacked graph below the total cost.  The graph also reacts on

       This view you can use for:

       · checking whether your application has memory leaks

       · finding expensive peaks

       · finding locations that significantly contribute to the  overall  memory  consumption  of
         your application

       The Snapshot Data Tree

       Directly  next to the above chart, you'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't add significant cost to
       your application.

       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.

       The Call Graph for Detailed Snapshots

       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 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.
