DescribeCloudRouterDCToDCTraffic

1. API Description

This API is used to query cloud router access point bandwidth information from data center to data center in the specified date range.

Note

• You can obtain data center information in the Layer 3 Cloud Router by calling the DescribeCloudRouters API.

• The time span between the start time and end time must not exceed one day.

• Only traffic data within the last 30 days can be queried.

• This API aggregates bandwidth data by data center and cannot distinguish traffic of individual access points within the same data center.\ For example, when querying bandwidth from data center A to Z, the returned result represents the total bandwidth from all access points in A to Z. It is not possible to retrieve bandwidth data between specific access points.

2. Input Parameters

The following request parameter list only provides API request parameters.

Parameter Name	Required	Type	Description
cloudRouterId	Yes	String	Layer 3 Cloud Router ID.
sourceDcId	Yes	String	Source data center ID.
destinationDcId	Yes	String	Destination data center ID.
startTime	Yes	Timestamp	Start time. Use UTC time according to the ISO8601 standard. Format: YYYY-MM-DDThh:mm:ssZ.
endTime	No	Timestamp	End time. Use UTC time according to the ISO8601 standard. Format: YYYY-MM-DDThh:mm:ssZ. End time is current time by default.

3. Output Parameters

Parameter Name	Type	Description
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
dataList	Array of TrafficData	List of bandwidth data.
in95	Float	Inbound burstable 95th bandwidth.
inAvg	Integer	Average value of inbound bandwidth.
inMax	Integer	Maximum value of inbound bandwidth.
inMin	Integer	Minimum value of inbound bandwidth.
out95	Integer	Outbound burstable 95th bandwidth.
outAvg	Integer	Average value of outbound bandwidth.
outMax	Integer	Maximum value of outbound bandwidth.
outMin	Integer	Minimum value of outbound bandwidth.
unit	String	Unit of bandwidth. For example, bps.

4. Code Example
