Directory Server stores recently-generated admin alerts in an Alerts Backend under the cn=alerts branch.
The backend makes it possible to obtain admin alert information over LDAP. The backend's
primary job is to process search operations for alerts. It does not support
modify DN operations
of entries in the cn=alerts backend.
The alerts persist on the server in the config/alerts.ldif file so they can survive server restarts. By default, the alerts remain in the system for seven days before being removed. Administrators can configure the number of days alerts are retained by using the dsconfig tool.
The administrative alerts of Warning level or worse that have occurred in the last 48 hours are viewable from the output of the status command-line tool and in the Administrative Console.
