The sched command.

positional arguments:

<path/to/trace>
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-validation
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
--period-key-value PERIOD_KEY_VALUE
Optional, define a fixed key value to which a period must correspond to be considered.

Filter the results only for this list of TIDs
--freq
Output the frequency distribution of sched switch latencies
--freq-resolution FREQ_RESOLUTION
Frequency distribution resolution (default 20)
--freq-uniform
Use a uniform resolution across distributions
--freq-series
Consolidate frequency distribution histogram as a single one
--limit LIMIT
Limit to top X (default = 10)
--top
Output the top sched switch latencies
--log
Output the sched switches in chronological order
--stats
Output sched switch statistics

--per-prio
Group results per-prio (applies to stats and freq)
