   optional arguments:
       -h, --help
              show this help message and exit

       -r REFRESH, --refresh REFRESH
              Refresh period, with optional units suffix (default units: s)

       --gmt  Manipulate timestamps based on GMT instead of local time

       --skip-validation
              Skip the trace validation

       --begin BEGIN
              start time: hh:mm:ss[.nnnnnnnnn]

       --end END
              end time: hh:mm:ss[.nnnnnnnnn]

       --period PERIOD
              Period definition

       --period-captures PERIOD_CAPTURES
              Period captures definition

       --period-begin PERIOD_BEGIN

       --period-begin-key PERIOD_BEGIN_KEY
              Optional, list of event field names used to match period markers (default: cpu_id)

       --period-end-key PERIOD_END_KEY
              Optional, list of event field names used to match period marker. If none specified,
              use the same --period-begin-key

       --period-key-value PERIOD_KEY_VALUE
              Optional, define a fixed key  value  to  which  a  period  must  correspond  to  be
