NAME
heaptrack - heap memory profiler for linux, command line utility
SYNOPSIS
heaptrack [--debug|-d] DEBUGGEE [ARGUMENT]...
heaptrack [--debug|-d] -p PID
DESCRIPTION
A heap memory usage profiler. It uses LD_PRELOAD to track all calls to
the core memory allocation functions and logs these occurrances. Addi-
tionally, backtraces are obtained and logged. Combined this can give
interesting answers to questions such as:
* How much heap memory is my application using? * Where is heap
memory being allocated, and how often? * How much space are
heap individual allocations requesting?
To evaluate the generated heaptrack data, use heaptrack_print or heap-
track_gui.
Mandatory arguments to heaptrack:
DEBUGGEE
The name or path to the application that should be run with
heaptrack analyzation enabled.
Alternatively, to attach to a running process:
-p, --pid PID
The process ID of a running process into which heaptrack will be
injected. This only works with applications that already link
against libdl.
Optional arguments to heaptrack:
-d, --debug
Run the debuggee in GDB and heaptrack.
ARGUMENT
Any number of arguments that will be passed verbatim to the de-
buggee.
-h, --help
Show this help message and exit.
-v, --version
Displays version information.
