Deleting Metric Field

Last updated: 2022-06-09 11:26:56

    Request address

    The address is the instance IP and port, such as 10.13.20.15:9200, which can be obtained in the console.

    Request path and method

    Path: /_metric/${metric_name}/delete, where ${metric_name} is the metric name.
    Method: PUT

    Request parameters

    None

    Request content

    Parameter Required Type Description
    tags No Array Enumeration of the tag fields to be deleted, such as "tags": ["ip"]
    fields No Array Enumeration of the data fields to be deleted, such as "fields": ["diskUsage"]
    Note:


    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.

    Response content
