2.9.8. Object Storage (swift) log files

OpenStack Object Storage sends logs to the system logging facility only.

注記

By default, all Object Storage log files go to /var/log/containers/swift/swift.log, using the local0, local1, and local2 syslog facilities.

The log messages of Object Storage are classified into two broad categories: those by REST API services and those by background daemons. The API service messages contain one line per API request, in a manner similar to popular HTTP servers; both the frontend (Proxy) and backend (Account, Container, Object) services post such messages. The daemon messages are less structured and typically contain human-readable information about daemons performing their periodic tasks. However, regardless of which part of Object Storage produces the message, the source identity is always at the beginning of the line.

Here is an example of a proxy message:

Here is an example of ad-hoc messages from background daemons:
