6. Understanding the Performance Analyzer and Its Data
The following commands control how the caller and callee information is displayed.
Print the callers-callees panel for each of the functions, in the order specified by the function sort metric (sort).
Within each caller-callee report, the callers and callees are sorted by the caller-callee sort metrics (csort). You can limit the number of panels written by using the limit command (see Commands That Control Output). The selected (center) function is marked with an asterisk, as shown in this example.
Attr. Excl. Incl. Name User CPU User CPU User CPU sec. sec. sec. 4.440 0. 42.910 commandline 0. 0. 4.440 *gpf 4.080 0. 4.080 gpf_b 0.360 0. 0.360 gpf_a
In this example, gpf is the selected function; it is called by commandline, and it calls gpf_a and gpf_b.
Write the callers-callees panel for the named function. The optional parameter N is needed for those cases where there are several functions with the same name. The callers-callees panel is written for the Nth function with the given function name. When the command is given on the command line, N is required; if it is not needed it is ignored. When the command is given interactively without N but N is required, a list of functions with the corresponding N value is printed.
When building a call stack, prepend the named function to the current call stack fragment. The optional parameter is needed where the function name is ambiguous; see source|src { filename | function_name } [ N] for more information about specifying the parameter.
When building a call stack, append the named function to the current call stack fragment. The optional parameter is needed where the function name is ambiguous; see source|src { filename | function_name } [ N] for more information about specifying the parameter.
When building a call stack, remove the top frame from the call stack segment.
When building a call stack, remove the bottom frame from the call stack segment.
