The irq command.

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)
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
--period-key-value PERIOD_KEY_VALUE
Optional, define a fixed key value to which a period must correspond to be considered.
--cpu CPU
Filter the results only for this list of CPU IDs
--timerange TIMERANGE
time range: [begin,end]
use trace size to approximate progress
disable stream intersection mode
-V, --version
show program's version number and exit
Enable debug mode (or set LTTNG_ANALYSES_DEBUG environment variable)
Disable colored output
Don't display the progress bar
--min MIN
Filter out durations shorter than min usec
--max MAX
Filter out durations longer than max usec
Output the frequency distribution of handler durations
--freq-resolution FREQ_RESOLUTION
Frequency distribution resolution (default 20)
Use a uniform resolution across distributions
Consolidate frequency distribution histogram as a single one
Output the IRQs in chronological order
Output IRQ statistics
--irq IRQ
Output results only for the list of IRQ
--softirq SOFTIRQ
Output results only for the list of SoftIRQ
