Why Does My Bucket Generate Traffic When There Are No Objects in It?

Principle for Generating Data Traffic

Sending requests to OBS generating data traffic when the requests or responses contain message bodies.

Traffic Types

OBS traffic is classified into inbound intranet traffic, outbound intranet traffic, inbound internet traffic, outbound internet traffic, cross-region replication traffic, and pull traffic. Not all traffic is billed. For details, see Billing Overview.

In What Situations Is Traffic Generated When There Are No Objects in a Bucket?

• Traffic is tallied once every hour. During this period, another user may have uploaded an object to the bucket and then deleted it. You would be billed for that traffic even though the bucket is currently empty.
• There could be multipart upload fragments in the bucket. Though fragments have not yet been merged into objects, they still generate traffic. You can list multipart tasks in the bucket or go to OBS Console to check if there are fragments.
• When access requests fail, responses with 4xx errors (except error 403) are returned and the message bodies of these responses generate traffic.
• Operations, such as configuring bucket ACLs and configuring lifecycle rules, contain message bodies that generate data traffic.

Monitoring OBS Data Traffic

You can enable Cloud Eye to monitor OBS operations, so that you can have a clear understanding about statistics including data traffic. For details, see Monitoring OBS.
