Offering and billable items

Key fields

On the Bill Details page in Billing Management, a CDT 2.0 bill includes the following sections: identification, identity, billing, product, resource, duration, usage, pricing, cost, subscription deduction, discount, coupon deduction, and payment information.

In the console, factors such as billing type, line type, resource type, and region are nested within the list price factor field (e.g., "Resource Type: Internet Shared Bandwidth instance") and do not appear as separate columns.

Offerings and billable items

CDT 1.0 includes the following offerings and billable items.

View CDT 2.0 bills

Go to the Billing Management > Bill Details page and filter by the following conditions:

• Product Name: Cloud Data Transfer

• Commodity Name: Cloud Data Transfer

• Bill Generation Date: Select the month that you want to query.

After applying the filters, you can view all CDT 2.0 bill details. Use the billable item code column to distinguish between internet data transfer (internet_traffic) and cross-region data transfer (inter_region_traffic).

View CDT 1.0 bills

Go to the Billing Management > Bill Details page and filter by the following conditions:

• Product Name: Cloud Data Transfer

• Commodity Name: Cloud Data Transfer - Internet or Cloud Data Transfer - Cross-region

• Bill Generation Date: Select the month that you want to query.

In CDT 1.0 bills, use the billable item name column (e.g., "ECS Fixed Public IP Traffic Fee", "IPv6 Pay-by-traffic") to identify the source cloud product directly.

View internet traffic costs by product

For CDT 2.0, after filtering for CDT 2.0 bills, locate the rows where the billable item code is internet_traffic. Check the "Resource Type" in the list price factor field to identify the source cloud product. For example:

• Resource type: ECS instance → ECS outbound internet traffic

• Resource type: EIP → EIP outbound traffic

• Resource type: Internet Shared Bandwidth instance → Internet Shared Bandwidth outbound traffic

To aggregate costs by cloud product, export the bill as a CSV file and group the data by resource type.

For CDT 1.0, the source cloud product is identified directly from the billable item name column without parsing the list price factor. For example:

• Billable item name: ECS Fixed Public IP Traffic Fee → ECS outbound internet traffic

• Billable item name: IPv6 Pay-by-traffic → IPv6 outbound traffic

• Billable item name: Anycast Internet Traffic → Anycast EIP outbound traffic

Identify high-usage instances

To locate specific instances that are generating high CDT internet traffic:

1. Go to Billing Management > Bill Details and filter by Product Name: Cloud Data Transfer.

2. In the bill details table, sort or filter by the Instance ID (billing granularity) column to rank instances by their usage volume.

3. The instance IDs correspond to specific cloud resources—such as an ECS instance or an Internet Shared Bandwidth instance—that are generating outbound internet traffic.

View cost proportion for a specific instance

To check how much a specific instance contributes to your total CDT costs:

1. On the Bill Details page, apply a filter for the target Instance ID (billing granularity).

2. The filtered results show the total deducted charges for that instance during the billing period. Compare this against your overall CDT spend for the same period to calculate the cost proportion.

Trace the source service by instance ID

If you need to confirm which service (such as Internet Shared Bandwidth) generated charges associated with a specific instance ID:

1. Copy the instance ID from the Bill Details page.

2. Go to Billing Management > Orders and search using the instance ID to trace the associated order and identify the source service or resource.

How do I troubleshoot rapid consumption of free traffic?

If your CDT free public network traffic is being consumed faster than expected, use the following steps to identify the cause:

1. Check the usage ranking: Log on to the CDT console. In the Public Network Traffic This Month area, view the usage ranking by cloud product. The table shows the product name, usage, and percentage for each product, sorted from highest to lowest. You can filter by region and line type to pinpoint the main source of consumption.

2. Export detailed bills for analysis: Click View Bill to go to the Bill Details page in Billing Management. Filter by Product Name: Cloud Data Transfer, then export the bill as a CSV file. Group the data by instance ID or resource type to analyze per-instance traffic consumption.

3. Common high-consumption scenarios: The following types of outbound internet traffic are common sources of high CDT usage:

   • ECS outbound internet traffic (large file transfers, frequent downloads)

   • EIP outbound traffic (public network access)

   • Global Accelerator (GA) public network traffic

   • Function Compute outbound traffic

   Note

   Some products must be upgraded to CDT before they appear in the usage ranking.

View cross-region traffic costs by region

After filtering for CDT bills, focus on the cross-region billable items:

• For CDT 2.0, locate the rows where the billable item code is inter_region_traffic.

• For CDT 1.0, focus on the billable items under the Commodity Name "Cloud Data Transfer - Cross-region" (such as CDTIR_Out_Bytes and AnycastInterRegionTraffic).

Use the Region and the region information within the list price factor to view the cost distribution of data transfers between different regions.

To distinguish the Chinese mainland traffic from non-mainland China (overseas) traffic consumption, use either of the following methods:

Method 1: Query via Bill Details

1. Go to Billing Management > Bill Details and filter by Product Name: Cloud Data Transfer.

2. In the Region column or the list price factor field, identify the region by its code:

   • Region codes starting with cn- (such as cn-hangzhou, cn-beijing) are the Chinese mainland regions.

   • Region codes not starting with cn- (such as ap-southeast-1, us-east-1) are outside the Chinese mainland (overseas) regions.

3. Filter by region code to view usage and costs for the Chinese mainland or overseas traffic separately.

Method 2: Query via CDT console overview

1. Log on to the CDT console overview page.

2. Use the region selector at the top of the page to switch between the Chinese mainland regions and regions outside the Chinese mainland.

3. The traffic consumption trend chart updates to show the current month's data transfer volume for the selected region, allowing you to monitor the Chinese mainland and overseas traffic separately.

View usage data

If you want to review historical CDT traffic consumption to evaluate resource plan specifications, or to compile traffic usage statistics across multiple cloud products, use the usage query feature in Billing Management.

Evaluate resource plan specifications

To determine the right resource plan size based on your historical CDT usage:

1. Go to Billing Management > Bill Details.

2. Set Product Name to Cloud Data Transfer and select the billing month or date range you want to review.

3. Refer to the Usage column in the detailed records to understand your historical traffic volume and use this data as a reference for resource plan purchases.

View cross-product traffic usage statistics

To get a consolidated view of data transfer usage across multiple cloud products:

1. Go to Billing Management > Usage Query.

2. Select the products and date range you want to analyze.

3. View and export the usage summary table to compile traffic statistics across cloud products in a single report.

Will my costs increase after the upgrade?

No. CDT 2.0 only changes the offering structure and bill display. The list price, tiered pricing rules, and free tier remain unchanged, so your bill amount is not affected by this upgrade.

Do I need to take any action for this upgrade?

No action is required. Starting May 20, 2026, new users use CDT 2.0 by default. Existing CDT 1.0 users are upgraded automatically in batches with no service impact.

Identify source product for costs

• For CDT 2.0, check the "Resource Type" information in the list price factor field. For example, "Resource Type: ECS instance" indicates the cost is from an ECS instance, and "Resource Type: EIP" indicates it is from an EIP.

• For CDT 1.0, you can directly identify the cloud product by the billable item name, such as "ECS Fixed Public IP Traffic Fee".

How to identify the free tier

• For CDT 2.0, use the Fee type column. A value of "Free Quota" indicates free traffic, while "Pay-As-You-Go Fee" indicates paid traffic.

• For CDT 1.0, use the list price factor column. If it contains "Traffic Tier: Monthly Free Internet Traffic", the traffic is free.

How do I determine whether an instance has exceeded the free tier?

To check the free tier status for a specific instance:

• Go to Billing Management > Bill Details and filter by Product Name: Cloud Data Transfer.

• Check the free tier status by CDT version:

  • For CDT 2.0: In the Fee type column, "Free Quota" indicates the traffic is within the free tier; "Pay-As-You-Go Fee" indicates paid traffic that has exceeded the free tier.

  • For CDT 1.0: In the list price factor column, if the value contains "Traffic Tier: Monthly Free Internet Traffic", the traffic is within the free tier.

• To view the traffic usage for a specific instance, enter the instance ID in the Instance ID (billing granularity) search box to filter by that instance and view its usage and fee type.

Can I still use my existing CDT resource plans?

Yes. CDT resource plans are compatible with both CDT 1.0 and CDT 2.0. You do not need to purchase new plans, and existing deduction rules remain unchanged.

Do my automation scripts need to be modified?

You may need to update your scripts. The offering codes and billable item codes have changed in CDT 2.0. If your scripts have hard-coded CDT 1.0 values such as the offering code cdt_internet_public_cn or the billable item code ECS_Out_Bytes, update them after the upgrade. We recommend supporting both old and new formats during the transition period.

How do I check overdue payment details?

When your account has an overdue payment, go to Billing Management > Bill Details to identify which CDT charges are outstanding:

1. Filter by Product Name: Cloud Data Transfer.

2. Review the bill details to identify the specific service with overdue charges—for example, Cloud Data Transfer - Internet.

3. Check the Billable item name column to identify the exact billable item—for example, Internet Shared Bandwidth Max Inbound/Outbound Traffic.

4. Check the Amount payable (including tax) column to see the outstanding amount for each line item.

How do I access billing information from the CDT console?

In addition to navigating through Billing Management, you can access your CDT bill directly from the CDT console:

1. Log on to the CDT console.

2. On the right side of the console, click the Billing shortcut entry.

3. You are redirected to the Bill Details page, where you can view a detailed breakdown of your traffic usage sources and costs.
