# QueryData

Available in Classic and VPC

Get the time-series data collected by Cloud Insight.

## Request

This section describes the request format. The method and URI are as follows:

| Method | URI |
| --- | --- |
| POST | /cw_fea/real/cw/api/data/query |

### Request headers

For information about the headers common to all Cloud Insight APIs, see [Cloud Insight request headers](/docs/en/management-cloudinsight#%EC%9A%94%EC%B2%AD%ED%97%A4%EB%8D%94).

### Request body

See [DataQueryRequest](/docs/en/common-vapidatatype-cidataqueryrequest) for more information about the fields related to data query request information.

              Note

              

When entering a request body, see the following:

- If the aggregation function (`aggregation`) configured when registering the schema and the aggregation of the data query request do not match, the data cannot be retrieved.
- The recommended query period (`timeEnd`~`timeStart`) varies depending on the data aggregation interval (`interval`). For more information, see [Recommended query period by data aggregation interval](https://guide.ncloud-docs.com/docs/en/cloudinsight-spec#%EB%8D%B0%EC%9D%B4%ED%84%B0-%EC%A7%91%EA%B3%84-%EC%A3%BC%EA%B8%B0%EB%B3%84-%EA%B6%8C%EC%9E%A5-%EC%A1%B0%ED%9A%8C-%EA%B8%B0%EA%B0%84).
