Access Log
The BLB supports 7-layer access log collection. After opening the access log service, we push your original access log to the bucket you select. For the charging, please refer to BOS Charging Rules. The BOS storage can guarantee the permanent storage of your log and facilitate management, download and analysis of your logs.
Before configuring the access log, you should ensure:
- The seven-layer load balance is created.
- The BOS service is opened.
Configuration access log
1.Log in to the Baidu AI Cloud platform, and select "Product Service>Baidu Load Balance (BLB)". Then click the BLB instance name to enter the details page of the BLB instance.
2.Click "Log" in the left navigation bar to enter the page of log configuration.
3.Fill in the following configuration information:
| Configuration items | Description |
|---|---|
| Stored in | Required. The bucket must exist. If it does not exist, the bucket should be created; the folder may not exist. If it doesn't exist, the system automatically create one. |
| Log prefix: | Not required. You can customize the log prefix. |
Note:
- The service publishing point has regional attributes, and can only bind to the regional BLB.
- A service publishing point in the "in service" state cannot be released, and the user needs to unbind the BLB or disassociate all associated NIC from it.
4.Click "Save". The service publishing point is created.
5.After configuring the load balance access log, you can view the log information in BOS.
