Whether you're using the included [OpenSearch Benchmark workloads](https://github.com/opensearch-project/opensearch-benchmark-workloads) or a [custom workload]({{site.url}}{{site.baseurl}}/benchmark/creating-custom-workloads/), use the `execute-test` command to gather data about the performance of your OpenSearch cluster according the selected workload.

## Options
Use the following options to customize the `execute-test` command for your use case. Options in this section are categorized by their use case.
## General settings
The following options shape how each test runs and how results are output.
-`--test-mode`: Runs the given workload in test mode, which is useful when checking a workload for errors.
-`--user-tag`: Defines user-specific key-value pairs to be used in metric record as meta information, for example, `intention:baseline-ticket-12345`.
-`--results-format`: Defines the output format for the command line results, either `markdown` or `csv`. Default is `markdown`.
-`--results-number-align`: Defines the column number alignment for when the `compare` command outputs results. Default is `right`.
-`--results-file`: When provided a file path, writes the compare results to the file indicated in the path.
-`--show-in-results`: Determines whether or not to include the comparison in the results file.
### Distributions
The following options set which version OpenSearch and OpenSearch plugins the benchmark test uses.
-`--distribution-version`: Downloads the specified OpenSearch distribution based on version number. For a list of released OpenSearch versions, see [Version history](https://opensearch.org/docs/version-history/).
-`--distribution-repository`: Defines the repository from where the OpenSearch distribution should be downloaded. Default is `release`.
-`--revision`: Defines the current source code revision to use for running a benchmark test. Default is `current`.
-`current`: Uses the source tree's current revision based on your OpenSearch distribution.
-`latest`: Fetches the latest revision from the main branch of the source tree.
- You can also use a time stamp or commit ID from the source tree. When using a timestamp, specify `@ts` where "ts" is a valid ISO 8601 timestamp, for example `@2013-07-27T10:37:00Z`.
-`--opensearch-plugins`: Defines which [OpenSearch plugins]({{site.url}}{{site.baseurl}}/install-and-configure/plugins/) to install. By default, no plugins are installed.
-`--plugin-params:` Defines a comma-separated list of key:value pairs that are injected verbatim into all plugins as variables.
-`--runtime-jdk`: The major version of JDK to use.
-`--client-options`: Defines a comma-separated list of clients to use. All options are passed to the OpenSearch Python client. Default is `timeout:60`.
### Cluster
The following option relates to the target cluster of the benchmark.
-`--target-hosts`: Defines a comma-separated list of host-port pairs which should be targeted if using the pipeline `benchmark-only`. Default is `localhost:9200`.
### Distributed workload generation
The following options help those who want to use multiple hosts to generate load to the benchmark cluster.
-`--load-worker-coordinator-hosts`: Defines a comma-separated list of hosts that coordinate loads. Default is `localhost`.
-`--enable-worker-coordinator-profiling`: Enables an analysis of the performance of OpenSearch Benchmark's worker coordinator. Default is `false`.
### Provisioning
The following options help customize how OpenSearch Benchmark provisions OpenSearch and workloads.
-`--provision-config-repository`: Defines the repository from which OpenSearch Benchmark loads `provision-configs` and `provision-config-instances`.
-`--provision-config-path`: Defines the path to the `--provision-config-instance` and any OpenSearch plugin configurations to use.
-`--provision-config-revision`: Defines a specific Git revision in the `provision-config` that OpenSearch Benchmark should use.
-`--provision-config-instance`: Defines the `--provision-config-instance` to use. You can see possible configuration instances using the command `opensearch-benchmark list provision-config-instances`.
-`--provision-config-instance-params`: A comma-separated list of key-value pairs injected verbatim as variables for the `provision-config-instance`.
### Workload
The following options determine which workload is used to run the test.
-`--workload-repository`: Defines the repository from where OpenSearch Benchmark loads workloads.
-`--workload-path`: Defines the path to a downloaded or custom workload.
-`--workload-revision`: Defines a specific revision from the workload source tree that OpenSearch Benchmark should use.
-`--workload`: Defines the workload to use based on the workload's name. You can find a list of preloaded workloads using `opensearch-benchmark list workloads`.
### Test procedures
The following options define what test procedures the test uses and which operations are contained inside the procedure.
-`--test-execution-id`: Defines a unique ID for this test run.
-`--test-procedure`: Defines a test procedure to use. You can find a list of test procedures using `opensearch-benchmark list test-procedures`.
-`--include-tasks`: Defines a comma-separated list of test procedure tasks to run. By default, all tasks listed in a test procedure array are run.
-`--exclude-tasks`: Defines a comma-separated list of test procedure tasks not to run.
-`--enable-assertions`: Enables assertion checks for tasks. Default is `false`.
### Pipelines
The `--pipeline` option selects a pipeline to run. You can find a list of pipelines supported by OpenSearch Benchmark by running `opensearch-benchmark list pipelines`.
### Telemetry
The following options enable telemetry devices on OpenSearch Benchmark.
-`--telemetry`: Enables the provided telemetry devices when the devices are provided using a comma-separated list. You can find a list of possible telemetry devices by using `opensearch-benchmark list telemetry`.
-`--telemetry-params`: Defines a comma-separated list of key-value pairs that are injected verbatim into the telemetry devices as parameters.
### Errors
The following options set how OpenSearch Benchmark handles errors when running tests.
-`--on-error`: Controls how OpenSearch Benchmark responds to errors. Default is `continue`.
-`continue`: Continues to run the test despite the error.
-`abort`: Aborts the test when an error occurs.
-`--preserve-install`: Keeps the Benchmark candidate and its index. Default is `false`.
-`--kill-running-processes`: When set to `true`, stops any OpenSearch Benchmark processes currently running and allows OpenSearch Benchmark to continue to run. Default is `false`.
