Overview: ${alarm_target} ${alarm_name}
Details: OceanBase cluster: ${ob_cluster_name}[${ob_cluster_id}], the capacity of the backup root folder ${storage_url} is over threshold, used percent: ${value}% >= threshold: ${threshold}%, please perform data compression or data dump !
Overview example: storage_url=xxxxxxx. The storage size exceeds a threshold. The used storage exceeds:${value}.
Details example: OceanBase cluster: clust01[5000034], the capacity of the backup root folder file:///obbackup/ is over threshold, used percent: 80% >= threshold: 70%, please perform data compression or data dump !
${alarm_target} follows the storage_url=xxxxxxx format, and ${value} follows the percentage format, for example, 80%.
Impact on the system
If the storage directory of backup is full, new backup data cannot be written in, which affects recovery of the backup cluster.
Possible causes
The storage directory of backup is set too small.
The retention period of backup is set too long.
Solutions
Expand the storage directory of backup.
Shorten the retention period of backup.
