The put_bucket_access_monitor interface enables or disables the access tracking feature for the bucket to record the last access time of objects.
Notes
- You need to fill in the region and access domain in the sample code according to the actual situation. For details, see Regions and endpoints.
- To prevent key leakage, the sample code reads the Access Key ID and Secret Access Key from environment variables. Therefore, before using the SDK, you need to configure long-term access credentials. For details, see Configure long-term access credentials.
- Access tracking is not supported for hierarchical buckets.
- After enabling access tracking, TOS records the last access time of all objects.
- Before disabling access tracking, all lifecycle rules of the last access time type must be deleted.
Permissions required
The Volcengine main account has all permissions by default, but IAM users have no permissions by default. If you need to use a sub-account to perform the put_bucket_access_monitor operation, the Volcengine main account must grant the following permissions to the sub-account through IAM policies and Bucket policies:
tos:PutBucketAccessMonitor
