Querying Bandwidth Usage Statistics

Function

This API is used to query average bandwidth usage (in bit/s) for a specific time range. Note that APIs related to the dashboard cannot be used to query data for a custom time range. Only data displayed on the console for yesterday, today, past 3 days, past 7 days, and past 30 days can be queried.

Calling Method

For details, see Calling APIs.

URI

GET /v1/{project_id}/waf/overviews/bandwidth/timeline

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID. To obtain it, go to Huawei Cloud management cons**. Then, in the Projects area, view Project ID of the corresponding project.

Table 2 Query Parameters

Parameter

Mandatory

Type

Description

enterprise_project_id

No

String

You can obtain the ID by calling the ListEnterpriseProject API of EPS.

from

Yes

Long

Start time (13-digit timestamp in millisecond) of the time range for which you want to query the average bandwidth usage. This parameter must be used together with to.

to

Yes

Long

End time (13-digit timestamp in millisecond) of the time range for which you want to query the average bandwidth usage. This parameter must be used together with from.

hosts

No

String

IDs of the domain names for which you want to query the bandwidth usage for a time range that is specified by from and to. In the cloud mode, domain name IDs can be obtained by calling the ListHost API. In the dedicated mode, domain name IDs can be obtained by calling the ListPremiumHost API.

instances

No

String

IDs of dedicated WAF instances. This parameter is used to query the average bandwidth usage of domain names protected by those dedicated WAF instances for a time range that is specified by from and to.

group_by

No

String

How data is displayed. For example, if the value is DAY, data is displayed by the day. If this parameter is not specified, the data is displayed by the minute.

display_option

No

Integer

Number of sent/received bytes. To view the peak value, enter 1. To view the average value, enter 0.

Request Parameters
