Resolution Logging Management
Updated at：2025-11-11
The resolution logging service monitors records of VPC domain name resolutions. Once the log push service is configured, DNS will begin sending logs to the designated BOS or BLS.
Before Configuration, users should understand:
- Each user can configure up to 50 resolution log push entries.
Create log push service
- Sign in to Cloud Management Console, select Products & Services - Network - Intelligent Cloud DNS;
- In the left navigation bar, select Resolution Logging to enter the Resolution Logging page
- Click Create Log Push Service button to pop up a dialog box. Fill in the following configuration details:
| ConfigMap | Description |
|---|---|
| Name | User-defined log push service name |
| Destination type | Select to push to BLS or BOS |
| Destination | Select a specific destination instance |
| Scope of collection | Select the VPC for which resolution logs need to be collected |
| Description | Fill in description, not exceeding 200 characters |
- Click OK to finalize setting up the resolution log push service.
Description:
- The resolution log push service itself is free; however, storage in Baidu Log Service (BLS) or Baidu Object Storage (BOS) will be charged according to their respective standard rates.
View resolution logs
Users need to store and view flow logs in BLS's LogStore or BOS's Bucket. For details, refer to LogStore Operation Guide and Bucket Operation Guide.
- Baidu Log Service (BLS) allows users to analyze logs, create metrics, and set up alerts to quickly identify service issues.
- Baidu Object Storage (BOS) provides economical long-term log archiving, but it typically has higher latency.
Resolution log fields are described below:
