Docs Self-Managed Reference rpk Commands rpk cluster rpk cluster self-test rpk cluster self-test start rpk cluster self-test start Starts one or more benchmark tests on one or more nodes of the cluster. Redpanda self-test runs benchmarks that consume significant system resources. Do not start self-test if large workloads are already running on the system. Available tests to run: Disk tests Throughput test: 512 KB messages, sequential read/write Uses a larger request message sizes and deeper I/O queue depth to write/read more bytes in a shorter amount of time, at the cost of IOPS/latency. Latency test: 4 KB messages, sequential read/write Uses smaller request message sizes and lower levels of parallelism to achieve higher IOPS and lower latency. Network tests Throughput test: 8192-bit messages Unique pairs of Redpanda nodes each act as a client and a server. The test pushes as much data over the wire, within the test parameters. Cloud storage tests Configuration/latency test: 1024-byte object. If cloud storage is enabled (cloud_storage_enabled), a series of remote operations are performed: Upload an object (a random buffer of 1024 bytes) to the cloud storage bucket/container. List objects in the bucket/container. Download the uploaded object from the bucket/container. Download the uploaded object’s metadata from the bucket/container. Delete the uploaded object from the bucket/container. Upload and then delete multiple objects (random buffers) at once from the bucket/container. This command prompts users for confirmation (unless the flag --no-confirm is specified), then returns a test identifier ID, and runs the tests. To view the test status, poll rpk cluster self-test status. Once the tests end, the cached results will be available with rpk cluster self-test status. Usage rpk cluster self-test start [flags] Flags Value Type Description --cloud-backoff-ms uint The backoff in milliseconds for a cloud storage request (default 100). --cloud-timeout-ms uint The timeout in milliseconds for a cloud storage request (default 5000). --disk-duration-ms uint The duration in milliseconds of individual disk test runs (default 30000). -h, --help - Help for start. --network-duration-ms uint The duration in milliseconds of individual network test runs (default 30000). --no-confirm - Acknowledge warning prompt skipping read from stdin. --only-cloud-test - Runs only cloud storage verification. --only-disk-test - Runs only the disk benchmarks. --only-network-test - Runs only network benchmarks. --participant-node-ids uints Comma-separated list of broker IDs that the tests will run on. If not set, tests will run for all node IDs. --config string Redpanda or rpk config file; default search paths are /var/lib/redpanda/.config/rpk/rpk.yaml, $PWD/redpanda.yaml, and /etc/redpanda/redpanda.yaml. -X, --config-opt stringArray Override rpk configuration settings. See rpk -X or execute rpk -X help for inline detail or rpk -X list for terser detail. --profile string Profile to use. See rpk profile for more details. -v, --verbose - Enable verbose logging.
