Code Tracing Statistics
Code Tracing Tree is accessed from Monitor | Tracing by selecting a trace ID from the list.
The Statistics per Function tab is a table based display that provides a statistical perspective of the data
captured in the request. The same data is displayed in two different ways. The “All functions” area at the
top that lists all the functions included in the dump for a certain occurrence and the “Calls for Functions”
area at the bottom that displays the function calls for a function selected from the list (by clicking on the
function).
Use this tab to investigate performance information such as the slowest function (sorting the table by 'own
time' will help pinpoint this).
The “All Functions” area includes the following columns:
Function Name: The name of the function as it appears in the code.
# of Calls: Function invocation count – how many times the function was called.
Memory Consumed (all calls, bytes): Graphical and numerical representation of the memory
consumed by all invocations of the function.
To highlight/disable the display of memory usage within the trace file, mark the check-box next to
"Show Memory Usage"
Total Running Time: Total time taken by this function’s invocations including nested function
calls. Hovering over shows a tooltip with the average time.
