positional arguments:
trace path

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 the trace validation

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

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

--period-begin PERIOD_BEGIN
Analysis period start marker event name

--period-end PERIOD_END
Analysis period end marker event name (requires --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
