NAME
mprof-heap-viewer - GUI viewer for the logging profiler heap snapshots
SYNOPSIS
mprof-heap-viewer file
DESCRIPTION
mprof-heap-viewer GUI viewer for the logging profiler heap snapshots
WARNING: this application is unfinished and experimental. Nevertheless it should work,
and bug reports are encouraged.
This program decodes the contents of a logging profiler output file and locates all the
heap snapshots inside it. The user can then select each individual snapshot and decide to
load it in memory and explore its contents.
The GUI is organized to work on "object sets" (listed in a tree view on the left). All
operations are performed with a popup menu on the choosen set.
Initially the sets are the heap snapshots (of course a heap snapshot can be considered a
set of objects!). For each set the GUI shows on the right a list that breaks it down by
class (one row for each class).
The user can then refine each set using a "filter", to select a subset. Examples of
filters are "all objects of class X", or "all objects that reference an object of class
X". This way the user explores the sets breaking them down to subsets (each subset in the
GUI is a child of its owner set on the tree view).
Moreover the user can issue a "compare" operation between two arbitrary sets A and B,
which will compute two subsets: "A - B" (the objects of A which are not in B, a subsect of
A) and "B - A" (the reverse). This can help in understanding what changed on the heap
between garbage collections.
