The Memory Hotspot Settings dialog controls the type of data that is displayed on the Hotspot tab.

 

 

 

 

Types of memory to display

 

The following types of memory allocations can all be optionally displaying in the hotspots view.

 

•CRT memory

•Win32 heap

•BSTR objects from SysAllocString function

•LocalAlloc()

•GlobalAlloc()

•Virtual memory

•Custom memory allocations using the Custom Hooks functionality

•User memory allocations using the API

•OpenGL

•FORTRAN memory

•Delphi memory

•COM objects

 

Only CRT Memory allocations are enabled by default.

 

Note that these settings control what is displayed, not what is collected. The data collection settings may have more information about some of the settings above.

 

 

Level of detail displayed

 

You can choose the level of detail displayed in each entry on the hotspots view:

 

•Address displays the address as part of a hotspot entry
 

•Module shows the module load address
 

•Path includes the full file path or just the filename when showing file and line below

 

•File and Line shows the filename and line number
 

•Units gives allocation sizes in Bytes, KB or MB

 

 

Allocation behaviour

 

Memory Validator refers to an allocation as having an allocation behaviour - indicating one of the following:

 

•Allocation

•Reallocation

•Deallocation
 

The default is to include all three behaviours in the hotspot calculations

 

 

Empty nodes

 

When the Memory tab option is set to show only live data rather than lifetime data, it is possible for the total number of bytes (or handles) displayed to be zero.

 

•Include empty nodes... include zero byte or zero handle entries in the hotspot listing

 

 

Refresh and reset

 

•Refresh the display... enables updates of the hotspot display whenever this settings dialog is closed
 

•Reset revert all these settings to the default values shown in the picture above
