\subsubsection{Instrumentation mode}
Here you will find a multi-column display of captured zones, which contains: the zone \emph{name} and \emph{location}, \emph{total time} spent in the zone, the \emph{count} of zone executions and the \emph{mean time spent in the zone per call}. You may sort the view according to the three displayed values.
Here you will find a multi-column display of captured zones, which contains: the zone \emph{name} and \emph{location}, \emph{total time} spent in the zone, the \emph{count} of zone executions, the \emph{mean time spent in the zone per call} and the number of threads the zone has appeared in, labeled with a \emph{\faRandom~thread icon}. You may sort the view according to the four displayed values or by the name.
In the \emph{~Timing} menu, the \emph{~With children} selection displays inclusive measurements, that is, containing execution time of zone's children. The \emph{~Self only} selection switches the measurement to exclusive, displaying just the time spent in the zone, subtracting the child calls. Finally, the \emph{~Non-reentrant} selection shows inclusive time but counts only the first appearance of a given zone on a thread's stack.

First and foremost, the presented information is constructed from many call stack samples, which represent real addresses in the application's binary code, mapped to the line numbers in the source files. This reverse mapping may not always be possible or could be erroneous. Furthermore, due to the nature of the sampling process, it is impossible to obtain exact time measurements. Instead, time values are guesstimated by multiplying the number of sample counts by mean time between two different samples.
The \emph{Name} column contains name of the function in which the sampling was done. Kernel-mode function samples are distinguished with the red color. If the \emph{\faSitemap{}~Inlines} option is enabled, functions which were inlined will be preceded with a '\faCaretRight{}' symbol and additionally display their parent function name in parenthesis. Otherwise, only non-inlined functions are listed, with a count of inlined functions in parenthesis. You may expand any entry containing an inlined function to display the corresponding functions list (some functions may be hidden if the \emph{\faPuzzlePiece{}~Show all} option is disabled due to lack of sampling data). Clicking on a function name will open the sample entry call stacks window (see chapter~\ref{sampleparents}). Note that if inclusive times are displayed, listed functions will be partially or completely coming from mid-stack frames, preventing, or limiting the capability to display parent call stacks.

The \emph{Location} column displays the corresponding source file name and line number. Depending on the \emph{Location} option selection, it can either show the function entry address or the instruction at which the sampling was performed. The \emph{Entry} mode points at the beginning of a non-inlined function or at the place where the compiler inserted an inlined function in its parent function. The \emph{Sample} mode is not useful for non-inlined functions, as it points to one randomly selected sampling point out of many that were captured. However, in the case of inlined functions, this random sampling point is within the inlined function body. Using these options in tandem lets you look at both the inlined function code and the place where it was inserted. If the \emph{Smart} location is selected, the profiler will display the entry point position for non-inlined functions and sample location for inlined functions. Selecting the \emph{\faAt{}~Address} option will instead print the symbol address.
