Procedure

  1. On the FusionInsight Manager portal choose O&M > Alarm > Alarms.
  2. In the alarm list, click in the row where the alarm is located and identify the data module from which the alarm is generated based on Additional Information.

  4. Configure a backup task. The backup data to be configured is consistent with the data in Additional Information of the alarm.

    Back up data to a third-party server, for example, remote HDFS (RemoteHDFS), NAS (NFS/CIFS), Object Storage Service (OBS), and SFTP server (SFTP). For details, see Backing Up Data.

  5. After the backup task is created successfully, wait for two minutes and check whether the alarm is cleared.

    • If yes, no further action is required.
