Simple Log Service:Log fields

Log type

Description

Detailed access logs

• You must manually enable the log collection feature for detailed access logs. For more information, see Enable the log collection feature.

• Detailed access logs include all access logs and logs that record the batch delete operations performed on your OSS buckets. Detailed access logs are collected in real time.

  Note

  • When you call the DeleteObjects operation, an access log is generated to record the request.

  • The oss-log-store Logstore may store both detailed access logs and hourly metering logs. Hourly metering logs are different from the following metering logs. The _topic_:oss_access_log field indicates detailed access logs, and the _topic_:oss_metering_log field indicates hourly metering logs.

Metering logs

• The log collection feature for metering logs is automatically enabled free of charge.

• This type of log records hourly metering data for a specified OSS bucket. The point in time at which a metering log is collected to Simple Log Service is several hours later than the point in time at which the metering log is generated. Metering logs are used to support analysis.

Metrics

• The log collection feature for metrics is automatically enabled free of charge.

• Metrics related to requests, latencies, and traffic are recorded at a granularity of 10 seconds. Metrics related to requests and traffic can also be recorded at a granularity of 5 minutes.
