+/*! @m_page{{c,java},operation_tracking,Track function calls}
+
+When this option is enabled, WiredTiger tracks all API calls as well as certain
+functions that are deemed important for performance, such as eviction-related
+functions. Tracking is performed by generating a log record when the WiredTiger
+library enters and exits a tracked function. A log record contains a function
+name and its timestamp. For the purposes of efficiency, the timestamp on most
+platforms is obtained directly from the CPU register, so the units of time
+correspond to processor clock ticks.
+
+By default, the log files are produced in the sub-directory
+`operation_tracking` of the database home directory. To change the
+destination directory, use the `path` sub-option of the
+`operation_tracking` option.
+
+Operation tracking produces two kinds of files: the binary log files
+and the map file. The map file is needed to convert the binary logs
+into text. The map file contains the mapping between numeric function
+ids used in the log files and the human-readable function name. The
+map file is called `optrack-map.<pid>`, where `pid` is the id of
+the process that generated the map file. Log files have names that
+look like `optrack.<pid>.<tid>`, where `tid` is the numeric id of the
+WiredTiger session that generated the log file.
+
+To convert binary log files to text, run the wt_optrack_decode.py script in the
+tools directory of the WiredTiger distribution. The script takes as arguments
+the list of log files and the name of the map file with the `-m` option. Suppose
+you would like to convert the log files generated by a process with `pid
+1234`. Then you would run the script as follows:
+
+```
+python wt_optrack_decode.py -m optrack-map.1234 optrack.1234.*
+```
+
+Enabling operation tracking may generate performance overhead if the tracked
+functions are executed frequently. Please be aware of this consequence and
+measure your performance before deciding whether to enable operation tracking.
