Configuring Logging¶
After logging is enabled for a bucket, OBS automatically converts the bucket's logs into an object in a fixed naming format and then writes the object to the specified bucket.
Prerequisites¶
The log delivery user group has the write and ACL view permissions for the destination bucket. For details, see Configuring a Bucket ACL.
Procedure¶
Log in to OBS Browser.
Click the blank area in the row of the bucket for which you want to configure logging and choose More > Configure Logging.
Select Enable. See Figure 1.
Figure 1 Configuring logging¶
Select an existing bucket where you want to store log files. Log delivery users of the selected bucket will be automatically granted the permissions to read the bucket ACL and write logs to the bucket.
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.
Click OK.
