Configuring the Number of Local Backup Audit Log Files

Configuring the Number of Local Backup Audit Log Files


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.


  1. Use PuTTY to 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.

  2. Run the following command to switch to the required directory:

    cd ${BIGDATA_HOME}/om-server/om/sbin

  3. Run the following command to change the maximum number of backup audit log files to be reserved:

    ./ -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
