The irq 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.
- --cpu CPU
- Filter the results only for this list of CPU IDs
- --timerange TIMERANGE
- time range: [begin,end]
- --progress-use-size
- use trace size to approximate progress
- --no-intersection

- -V, --version
- show program's version number and exit
- --debug
- Enable debug mode (or set LTTNG_ANALYSES_DEBUG environment variable)
- --no-color
- Disable colored output
- --no-progress
- Don't display the progress bar
- --min MIN
- Filter out durations shorter than min usec
- --max MAX
- Filter out durations longer than max usec
- --freq
- Output the frequency distribution of handler durations
- --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
- --log
- Output the IRQs in chronological order
- --stats
- Output IRQ statistics
- --irq IRQ
- Output results only for the list of IRQ
- --softirq SOFTIRQ
-
Output results only for the list of SoftIRQ
