Configuring Audit Log Dumping Parameters

Scenario

If audit logs are stored in the database for a long time, the disk space for the data directory may be insufficient. Therefore, you can set dump parameters to automatically dump audit logs to a specified directory on a server.

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_HOME}/OMSV100R001C00x8664/workspace/conf/data/operatelog on the active management node. The file name format is OperateLog_store_YY_MM_DD_HH_MM_SS.csv. A maximum of 50 historical audit log files can be saved. The directory is automatically generated when audit logs are dumped for the first time.

Prerequisites

The ECS corresponding to the dump server must be in the same VPC as the master node of the MRS cluster, and the master node can access the IP address and specified port of the dump server. The SFTP service on the dump server is running properly.

Procedure

  1. On MRS Manager, click System.
  2. Choose Dump Audit Log under Maintenance.
