Configuring Audit Log Dumping¶
Scenario¶
The audit logs of MRS Manager are stored in the database by default. If the audit logs are retained for a long time, the disk space of the data directory may be insufficient. To store audit logs to another archive server, administrators can set the required dump parameters to automatically dump these logs. This facilitates the management of audit logs.
If you do not configure the audit log dumping, the system automatically saves the audit logs to a file when the number of audit logs reaches 100,000 pieces. The save path is ${BIGDATA_DATA_HOME} /dbdata_om/dumpData/iam/operatelog on the active management node. The file name format is OperateLog_store_YY_MM_DD_HH_MM_SS.csv. The maximum number of historical audit log files is 50.
Procedure¶
Log in to MRS Manager.
Choose Audit > Configuration.
Click the switch on the right of Audit Log Dumping Flag.
Audit Log Dump is disabled by default. If
