Run a test tool or benchmark to collect test data.
- -h
- Show this help message and exit.
- -q
- Be quiet.
- -d
- Print debugging information.
- -H HOSTNAME, --host HOSTNAME
- Name of the host to run the command on.
- -U USERNAME, --username USERNAME
- Name of the user to use for logging into the remote host over SSH. The default user name is 'root'.
- -K PRIVKEY, --priv-key PRIVKEY
- Path to the private SSH key that should be used for logging into the remote host. By default the key is automatically found from standard paths like '~/.ssh'.
- -T TIMEOUT, --timeout TIMEOUT
- SSH connect timeout in seconds, default is 8.
- --datapoints DATAPOINTS, -c DATAPOINTS
- Applicable only to 'wult' and 'ndl' tools. Number of datapoints to collect per measurement. Default is 100000.
- --reportid-prefix REPORTID_PREFIX
- String to prepend to the report ID.
- --reportid-suffix REPORTID_SUFFIX
- String to append to the report ID.
- --cpunums CPUNUMS
- Applicable only to the 'wult' and 'ndl' tools. Comma-separated list of CPU numbers to measure with.
- --cstates CSTATES
- Comma-separated list of requestable C-states to measure with.
- --pcstates PCSTATES
- Comma-separated list of package C-states to measure with.
- --turbo TURBO
- Comma-separated list of turbo configurations to measure with. Supported values are "on" and "off".
- --freqs FREQS
- Comma-separated list of frequencies to be measured with. For more information, see '--min-freq' and '--max-freq' options of the 'pepc pstates config' command. Special value 'unl' can be used to measure with unlocked frequency (minimum frequency set to smallest supported value, and maximum frequency set to highest supported value.
- --uncore-freqs UNCORE_FREQS
- Comma-separated list of package uncore frequencies to measure with. For more information, see '--min-uncore-freq' and '--max-uncore-freq' options of the 'pepc pstates config' command. Special value 'unl' can be used to measure with unlocked frequency (minimum frequency set to smallest supported value, and maximum frequency set to highest supported value.
- --governor GOVERNOR
- Name of the CPU frequency governor to measure with.
- --aspm ASPM
- Comma-separated list of PCIe ASPM configurations to measure with. Supported values are "on" and "off".
- --c1-demotion C1_DEMOTION
- Comma-separated list of C1 demotion configurations to measure with. Supported values are "on" and "off".
- --c1-undemotion C1_UNDEMOTION
- Comma-separated list of C1 undemotion configurations to measure with. Supported values are "on" and "off".
- --c1e-autopromote C1E_AUTOPROMOTE
- Comma-separated list of C1E autopromote configurations to measure with. Supported values are "on" and "off".
- --cstate-prewake CSTATE_PREWAKE
- Comma-separated list of C-state prewake configurations to measure with. Supported values are "on" and "off".
- --epp EPP
- Comma-separated list of EPP configurations to measure with. See 'pepc pstates config --epp' for more information.
- --epb EPB
- Comma-separated list of EPB configurations to measure with. See 'pepc pstates config --epb' for more information.
- --state-reset
- Set SUT settings to default values before starting measurements. The default values are: online all CPUs, enable all C-states, disable C1 demotion, disable C1 undemotion, disable C1E autopromotion, disable C-state prewake, enable turbo, unlock CPU frequency, unlock uncore frequency, set EPP policy to 'balance_performance', set EPB policy to 'balance-performance'.
- --deploy
- Applicable only to 'wult' and 'ndl' tools. Run the 'deploy' command before starting the measurements.
- --devids DEVIDS
- Applicable only to 'wult' and 'ndl' tools. Comma-separated list of device IDs to run the tools with.
- --stats STATS
- Applicable to 'wult', 'ndl' 'stats-collect'tools. Comma-separated list of statistics to collect.
- --command COMMAND
- Applicable only to 'stats-collect' tool. The command to that 'stats-collect' should run.
- --stop-on-failure
- Stop if any of the steps fail, instead of continuing (default).
- --only-measured-cpu
- Change settings, for example CPU frequency and C-state limits, only for the measured CPU. By default settings are applied to all CPUs.
- --toolpath TOOLPATH
- Path to the tool to run. Default is 'wult'.
- --only-one-cstate
- By default C-states deeper than measured C-state are disabled and other C-states are enabled. This option will disable all C-states, excluding the measured C-state.
- --cstates-always-enable CSTATES_ALWAYS_ENABLE
- Comma-separated list of always enabled C-states.
- --use-cstate-filters
- Applicable to 'wult' and 'ndl' tools. Use filters to exclude datapoints with zero residency of measured C-state.
- --toolopts TOOLOPTS
- Additional options to use for running the tool. The string "__reportid__" will be replaced with generated report ID.
- --outdir OUTDIR, -o OUTDIR
- Path to directory to store the results at. Default is <toolname-date-time>.
- --dry-run
- Do not run any commands, only print them.
- --list-monikers
- A moniker is an abbreviation for a setting. The 'exercise-sut' uses monikers to create directory names and report IDs for collected results. Use this option to list monikers assosiated with each settings, if any, and exit.
