Call Tree View - Profiler Sampling Data

The Call Tree view displays the function execution paths that were traversed in the profiled application. The root of the tree is the entry point into the application or the component. Each function node lists all the functions that it called and performance data about those function calls.

The values in the Call Tree view are for the function instances that were called by the parent function in the call tree. Percentage values are calculated by comparing the function instance value to the total number of samples in the profiling run.

The Call Tree view can expand and highlight the execution path of the process or function that was sampled most frequently. To display the most active path, right-click the process or function and then click Expand Hot Path.

Each process in the profiling run is displayed as a root node. To set the start node of the Call Tree view, right-click the node that you want to set as the start node and select Set Root.

When you set the root node, you eliminate all other entries from the view except the subtree of the selected node. To reset the root node back to the original node, right-click in the Call Tree View window and select Reset Root.

Column

Description

Process ID

The process ID (PID) of the profiling run.

Process Name

The name of the process.

Module Name

The name of the module that contains the function.

Module Path

The path of the module that contains the function.

The source file that contains the definition for this function.

Function Name

The fully qualified name of the function.

Function Line Number

The line number of the start of this function in the source file.

Function Address

The address of the function.

Level

The depth of this function in the call tree. Only in VSPerfReport command-line reports.

Exclusive Samples

The number of samples that were collected in this function when it was called by the parent function in the call tree. This number does not include samples that were collected in functions that were called by the function.

Exclusive Samples %

The percentage of all samples in the profiling run that were exclusive samples of this function when it was called by the parent function in the call tree.

Inclusive Samples

The number of samples that were collected in this function when it was called by the parent function in the call tree. This number includes samples that were collected in functions that were called by the function.

Inclusive Samples %

The percentage of all samples in the profiling run that were inclusive samples of this function when it was called by the parent function in the call tree.
