This directive returns the statistics of the rate monotonic period specified
by ${.:/params[0]/name}. The statistics of the period will be returned in
the members of the period statistics object referenced by
${.:/params[1]/name}:
* The ``count`` member is set to the number of periods executed.
* The ``missed_count`` member is set to the number of periods missed.
* The ``min_cpu_time`` member is set to the least amount of processor time
used in the period.
* The ``max_cpu_time`` member is set to the highest amount of processor time
used in the period.
* The ``total_cpu_time`` member is set to the total amount of processor time
used in the period.
* The ``min_wall_time`` member is set to the least amount of
${/glossary/clock-monotonic:/term} time used in the period.
* The ``max_wall_time`` member is set to the highest amount of
${/glossary/clock-monotonic:/term} time used in the period.
* The ``total_wall_time`` member is set to the total amount of
${/glossary/clock-monotonic:/term} time used in the period.
