## Write data

The following command collects system metric data, such as CPU and memory usage, and sends them to GreptimeCloud. This demo is based on OpenTelemetry OTLP/http. The source code is available on [GitHub](https://github.com/GreptimeCloudStarters/quick-start-node-js).

```shell
npx greptime-cloud-quick-start@latest --endpoint=https://<host>/v1/otlp/v1/metrics --db=<dbname> --username=<username> --password=<password>
