# Data loader The tool populates a database with sample data. Generate sample data with dataloader: ``` go run ./pkg/testing/load/cmd/dataloader -path config.yml ``` See example `config.yml` in `dataloader` directory for details. The loader writes data directly to the storage, the path should be specified in the configuration file: ```yaml storage: path: test_storage ``` Start server with `-storge-path` option (if `pyroscope server` is run in a container, you can map the volume): ``` pyroscope server -storage-path test_storage ```
