OpenSearch Benchmark quickstart
This tutorial outlines how to quickly install OpenSearch Benchmark and run your first OpenSearch Benchmark workload.
Prerequisites
To perform the Quickstart steps, you’ll need to fulfill the following prerequisites:
- A currently active OpenSearch cluster. For instructions on how to create an OpenSearch cluster, see Creating a cluster.
- Git 2.3 or greater.
Additional prerequisites are required, depending on your installation method:
- If you plan to install OpenSearch Benchmark with PyPi, install Python 3.8 or later.
- If you plan to install OpenSearch Benchmark using Docker, install Docker.
Installing OpenSearch Benchmark
You can install OpenSearch Benchmark using either PyPi or Docker.
If you plan to run OpenSearch Benchmark with a cluster using AWS Signature Version 4, see Sigv4 support.
PyPi
To install OpenSearch Benchmark with PyPi, enter the following pip command:
pip3 install opensearch-benchmark
After the installation completes, verify that OpenSearch Benchmark is running by entering the following command:
opensearch-benchmark --help
If successful, OpenSearch returns the following response:
$ opensearch-benchmark --help
usage: opensearch-benchmark [-h] [--version] {execute-test,list,info,create-workload,generate,compare,download,install,start,stop} ...

Find out more about Benchmark at https://opensearch.org/docs
Docker
To pull the image from Docker Hub, run the following command:
docker pull opensearchproject/opensearch-benchmark:latest
Then run the Docker image:
docker run opensearchproject/opensearch-benchmark -h
Running your first benchmark
You can now run your first benchmark. For your first benchmark, you’ll use the geonames workload.
Understanding workload command flags
Benchmarks are run using the execute-test command with the following command flags:
For additional execute_test command flags, see the execute-test reference. Some commonly used options are --workload-params, --exclude-tasks, and --include-tasks.
--pipeline=benchmark-only: Informs OSB that users wants to provide their own OpenSearch cluster.workload=geonames: The name of workload used by OpenSearch Benchmark.--target-host="<OpenSearch Cluster Endpoint>": Indicates the target cluster or host that will be benchmarked. Enter the endpoint of your OpenSearch cluster here.--client-options="basic_auth_user:'<Basic Auth Username>',basic_auth_password:'<Basic Auth Password>'": The username and password for your OpenSearch cluster.--test-mode: Allows a user to run the workload without running it for the entire duration. When this flag is present, Benchmark runs the first thousand operations of each task in the workload. This is only meant for sanity checks—the metrics produced are meaningless.
The --distribution-version, which indicates which OpenSearch version Benchmark will use when provisioning. When run, the execute-test command will parse the correct distribution version when it connects to the OpenSearch cluster.
Running the workload
If you installed Benchmark with PyPi, customize and use the following command:
opensearch-benchmark execute-test --pipeline=benchmark-only --workload=geonames --target-host="<OpenSearch Cluster Endpoint>" --client-options="basic_auth_user:'<Basic Auth Username>',basic_auth_password:'<Basic Auth Password>'" --test-mode
If you installed Benchmark with Docker, customize and use the following command:
docker run opensearchproject/opensearch-benchmark execute-test --pipeline=benchmark-only --workload=geonames --target-host="<OpenSearch Cluster Endpoint>" --client-options="basic_auth_user:'<Basic Auth Username>',basic_auth_password:'<Basic Auth Password>'" --test-mode
When the execute_test command runs, all tasks and operations in the geonames workload run sequentially.
Understanding the results
Benchmark returns the following response once the benchmark completes:

Each task run by the geonames workload represents a specific OpenSearch API operation—such as Bulk or Search—that was performed when the test was run. Each task in the output summary contains the following information:
- Throughput: The number of successful OpenSearch operations per second.
- Latency: The amount of time, including wait time, taken for the request and the response to be sent and received by Benchmark.
- Service Time: The amount of time, excluding wait time, taken for the request and the response to be sent and received by Benchmark.
- Error Rate: The percentage of operations run during the task that were not successful or returned a 200 error code.
