Notes
As historical data cannot be modified, after fields are deleted, the metric information will not change until the next child metric is generated. If you want to check whether the deletion is successful, you can call the
GET /_metric/${metric_name}?v API. For more information about child metric, see Creating Metric.Response
You can check whether a request is successful based on the
error field. If the response content contains the error field, the request failed. For the error details, see the error field description.Sample code for curl
