Caller/Callee View - Profiler .NET Memory Instrumentation Data

  • Article

The Caller/Callee view of .NET memory profiling data that was collected by using the instrumentation method displays allocation and timing data for a selected function and the parent and child functions of that selected function. The Caller/Callee view contains three grids.

Current function is displayed in the middle grid, and it shows memory profiling information about the selected function. The values include all sampled calls to the function.

Functions that called the current function is displayed in the top grid, and it shows the amount of the value of the selected (current) function that was generated by calls from the caller (parent) function.

Functions that were called by the current function is displayed in the bottom grid, and it shows memory profiling data for the callee (child) functions of the selected function when the child function was called by the current function.

Double-click a caller or callee function row to make that row the current function.

  • For a caller function, the number of the exclusive bytes of the current function that were generated from calls by this caller function.

  • For a callee function, the number of bytes that were allocated by the instances of this function that were generated by calls from the current function. The number does not include bytes that were allocated by functions that were called by the callee function.

Exclusive Bytes %

The percentage of all bytes of memory that were allocated in the profiling run that were exclusive allocations of this function.

Inclusive Bytes

  • For the current function, the number of bytes in memory that were allocated by the function in the profiling run. The number includes memory that was allocated in callee functions that were called by the function.

  • For a caller function, the number of the inclusive bytes of the instances of the current function that were generated by calls from this caller function.

  • For a callee function, the number of bytes that were allocated by the instances of this function that were generated by calls from the current function. The number includes bytes that were allocated by functions that were called by this callee function.

Inclusive Bytes %

The percentage of all bytes of memory that were allocated in the profiling run that were inclusive allocations of this function.

Elapsed Inclusive Values

Elapsed inclusive values indicate the time that a function was on the call stack. The time includes time that was spent in child functions and in calls to the operating system, such as context switches and input/output operations.

Column

Description

  • For the current function, the time that was spent in the function. The value includes time that was spent in child functions and in calls to the operating system, such as context switches and input/output operations.

  • For a caller function, the amount of the elapsed inclusive time of the current function that was generated by calls from this caller function.
