The NDB alert retention feature allows the database administrator to configure the duration for

which the NDB alerts are stored and displayed in the NDB instance. The NDB alert retention feature

supports alert retention globally, meaning that the same retention period applies to all the alerts

generated by the NDB instance, regardless of the source cluster, policy, or operation. The database

administrator can set the alert retention period from 1 day to 365 days, or choose to retain the alerts

indefinitely. The NDB alert retention feature helps to manage the storage space and the visibility of

the NDB alerts.

The NDB alert retention feature does not support retention at the individual policy, grouped policy,

or registered cluster level. The NDB alert retention feature applies to all the alerts uniformly, and

does not allow the database administrator to specify different retention periods for different policies

or clusters.
