- sample: Number of sample
- period: Raw number of event count of sample
+ - time: Separate the samples by time stamp with the resolution specified by
+ --time-quantum (default 100ms). Specify with overhead and before it.
By default, comm, dso and symbol keys are used.
(i.e. --sort comm,dso,symbol)
Please note that not all mmaps are stored, options affecting which ones
are include 'perf record --data', for instance.
+--ns::
+ Show time stamps in nanoseconds.
+
--stats::
Display overall events statistics without any further processing.
(like the one at the end of the perf report -D command)
The period/hits keywords set the base the percentage is computed
on - the samples period or the number of samples (hits).
+--time-quantum::
+ Configure time quantum for time sort key. Default 100ms.
+ Accepts s, us, ms, ns units.
