Back Traces

As well as the call tree, the Back Traces view shows the list of calls that have created a certain object set. But unlike the call tree, calls are shown starting from the one that directly created an object set and descending to the first call in the stack. In other words, Back Traces is the inverted Call Tree.

The list of calls consists of the following columns:

Name

Description

Function

Function name.

Bytes

The size of objects allocated by a call.

Objects count

The number of objects allocated by a call.

Namespace

The namespace a call belongs to.

Because of the .NET nature, profiling can be started only after an app performs some initialization routines. That is why there are a number of objects for which allocation information is not available. These are, for example, System.OutOfMemoryException, System.StackOverflowException, and others. All such objects are grouped under the Objects allocated before the profiling session item in the stack trace.

Sometimes, dotMemory can't collect allocation data for some objects during profiling. All such objects are grouped under the Objects skipped during the profiling session item in the stack trace.

Select objects for further analysis

When viewing allocations in the Back Traces mode, the following objects are available for further analysis:

To select objects allocated by a certain stack trace

  • Do one of the following:

    • Double-click the last call in the sequence.

    • Right-click the call and select Open objects allocated in this stack trace.

    After this, the Created in instance of function [function_name] subject will be added to the Analysis Path and desired objects will be displayed in the Group by Types view.

To select the objects that are exclusively retained by the analyzed objects set

  • Click the Open retained objects Open objects retained by this set button.

    After this, the Exclusively retained objects subject will be added to the analysis path on the left and the list of desired objects will be displayed in the Group by Types view.
