ALM-12001 Audit Log Dumping Failure

Description

Cluster audit logs need to be dumped on a third-party server due to the local historical data backup policy. The system starts to check the dump server at 3 a.m. every day. If the dump server meets the configuration conditions, audit logs can be successfully dumped. This alarm is generated when the audit log dump fails if the disk space of the dump directory on the third-party server is insufficient or a user changes the username, password, or dump directory of the dump server.
