Queries the monitoring data of a secondary elastic network interface (ENI) over a specific period of time.
Operation description
Usage notes
The monitoring data of a secondary ENI includes the amount of traffic sent and received over the internal network, the number of packets sent and received by the secondary ENI, and the number of sent and received packets that are dropped by the secondary ENI. Specific information may be missing from the returned monitoring data. This may be because the system cannot obtain the relevant information. For example, if the instance to which the secondary ENI is attached is in the Stopped state or if the secondary ENI is not attached to an instance and is in the Available state, the monitoring data of the secondary ENI cannot be obtained. Take note of the following items:
- Up to 400 monitoring data entries can be returned at a time. Make sure that the
TotalCountvalue does not exceed 400. The value is calculated by using the following formula:TotalCount = (EndTime - StartTime)/Period. If the TotalCount value is greater than 400, theInvalidParameter.TooManyDataQueriederror is returned. - You can query the monitoring data in the last 30 days. If the value of
StartTimeis more than 30 days earlier than the current time, an error is returned.

Authorization information
The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:
- Operation: the value that you can use in the Action element to specify the operation on a resource.
- Access level: the access level of each operation. The levels are read, write, and list.
- Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level,
All Resourcesis used in the Resource type column of the operation.
- Condition Key: the condition key that is defined by the cloud service.
- Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| EniId | string | No | The secondary ENI ID. By default, all secondary ENIs that are bound to the specified instance are queried. | eni-bp19da36d6xdwey**** |
| RegionId | string | Yes | The region ID. You can call the DescribeRegions operation to query the most recent region list. | cn-hangzhou |
| InstanceId | string | Yes | The ID of the instance to which the secondary ENI is bound. | i-bp1a5zr3u7nq9cx**** |
| StartTime | string | Yes | The beginning of the time range to query. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC. If the value of seconds (ss) is not 00, the time is rounded up to the next minute. | 2018-05-21T12:19:00Z |
| EndTime | string | Yes | The end of the time range to query. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC. If the value of seconds (ss) is not 00, the time is rounded up to the next minute. | 2018-05-21T12:22:00Z |
| Period | integer | No | The interval at which to retrieve monitoring data. Unit: seconds. Valid values:
Default value: 60. | 60 |
