Configuring the Number of Local Backup Audit Log Files
Scenarios
Audit logs of cluster components are classified by name and stored in the /var/log/Bigdata/audit directory on each cluster node. The OMS automatically backs up the audit log directories at 03:00 every day.
The audit log directory on each node is compressed and named in the <IP address of the node>.tar.gz format. All compressed files are compressed and named in the <yyyy-MM-dd_HH-mm-ss>.tar.gz format and saved in the /var/log/Bigdata/audit/bk/ directory on the active management node. In addition, the standby management node saves a copy of it.
By default, the maximum number of files that can be backed up by the OMS is 90. System administrators can configure the maximum number.
Procedure
- Log in to the active management node as user omm.
Perform this operation only on the active management node. This operation is not supported on the standby management nodes; otherwise, the cluster cannot work properly.
- Run the following command to switch to the required directory:
cd ${BIGDATA_HOME}/om-server/om/sbin
- Run the following command to change the maximum number of backup audit log files to be reserved:
./modifyLogConfig.sh -m Maximum number of backup files that can be reserved by OMS
The default value is 90. The value ranges from 0 to 365. The greater the value is, the larger disk space is occupied.
If the following information is displayed, the operation is successful:
Modify log config successfully
