Configuring Logging

Prerequisites

The log delivery user group has been assigned the Write and ACL View permissions for the target bucket. For details, see Configuring a Bucket ACL.

Procedure

1. Log in to OBS Browser.
2. Click the blank area in the row of the bucket for which you want to configure logging and choose More > Configure Logging.
3. Select Enable. See Figure 1.
   Figure 1 Logging
   

4. Select an existing bucket where you want to store log files.
5. Enter a prefix for the Log File Name Prefix.

   After logging is enabled, generated logs are named in the following format:

   <Log File Name Prefix>YYYY-mm-DD-HH-MM-SS-<UniqueString>

   • <Log File Name Prefix> is the shared prefix of log file names.
   • YYYY-mm-DD-HH-MM-SS indicates when the log is generated.
   • <UniqueString> indicates a character string generated by OBS.

   On OBS Console, if the configured <Log File Name Prefix> ends with a slash (/), logs generated in the bucket are stored in the <Log File Name Prefix> folder in the bucket, facilitating the management of log files.

   Example:

   • If the bucket named bucket is used to save log files, and the log file name prefix is set to bucket-log/, all log files delivered to this bucket are saved in the bucket-log folder. A log file is named as follows: 2015-06-29-12-22-07-N7MXLAF1BDG7MPDV.
   • If the bucket named bucket is used to save log files, and the log file name prefix is set to bucket-log, all log files are saved in the root directory of the bucket. A log file is named as follows: bucket-log2015-06-29-12-22-07-N7MXLAF1BDG7MPDV.

6. Click Save.
7. In the displayed dialog box, click OK to close the dialog box.
