The following tables describe the headers and parameters in an HTTP request that is used to report monitoring data.

• Request headers

  Header	Type	Description	Example
  Authorization	String	The authorization string that is in the AccessKeyID:SignString format. For information about how to obtain the AccessKey ID, see Obtain an AccessKey pair. For more information about how to sign a string, see Does Cloud Monitor support the HMAC-SHA1 signature algorithm and how do I use it?	testKey:F86ADF652A6466FCCD860B867D9518D48C24E7F6
  Content-Length	Long	The body length of the HTTP request that is defined in RFC 2616. The request body is measured by the number of bytes encoded in UTF-8. Note This header is required only if the request has a body.	151
  Content-MD5	String	The MD5 hash of the HTTP request body. The MD5 hash is a string that consists of uppercase letters and digits. Note This header is required only if the request has a body.	215614AA47799058C009D3E20B19B83A
  Content-Type	String	The type of the content that is sent in the HTTP request. Set the value to application/json.	application/json
  Date	String	The standard timestamp header of the HTTP request. This timestamp header follows the time format defined in RFC 1123 and uses the UTC standard time. Example: Mon, 3 Jan 2010 08:33:47 UTC.	Fri, 27 Aug 2021 06:33:55 GMT
  Host	String	The full hostname of the HTTP request. This header does not include protocol headers such as https://. Example: metrichub-cms-cn-hangzhou.aliyuncs.com.	metrichub-cms-cn-hangzhou.aliyuncs.com
  x-cms-api-version	String	The version of the API. Set the value to 1.0.	1.0
  x-cms-signature	String	The signature algorithm. Cloud Monitor supports the HMAC-SHA1 signature algorithm.	hmac-sha1
  x-cms-ip	String	The IP address of the host that reports the monitoring data.	192.168.XX.XX
  User-Agent	String	The description of the client.	cms-java-sdk-v-1.0

• Request parameters

  Parameter	Type	Required	Description
  groupId	Long	Yes	The ID of the application group.
  metricName	String	Yes	The name of the metric. For more information, see Appendix 1: Metrics.
  dimensions	Object	Yes	The dimensions that specify the resources whose monitoring data you want to query. The value is a collection of key-value pairs. A typical pair is instanceId:i-abcdefgh12****.
  time	String	Yes	The timestamp when the metric is generated. Valid values: yyyyMMdd'T'HHmmss.SSSZ Example: 20171012T132456.888+0800 long Example: 1508136760000
  type	Int	Yes	The type of the reported data. Valid values: 0 and 1. The value 0 indicates raw data and the value 1 indicates aggregate data. We recommend that you report aggregate data in both the aggregation periods of 60s and 300s. Otherwise, you cannot query monitoring data in a time span that is more than seven days.
  period	String	No	The aggregation period. Unit: seconds. If the type parameter is set to 1, the period parameter is required. Valid values: 60 300
  values	Object	Yes	The collection of metric values. If the type parameter is set to 0, the keys in this parameter must be set to the specified value. Cloud Monitor aggregates raw data in each aggregation period to generate multiple statistical values, such as the maximum value, the count, and the total value.
