You can configure alerts to get prior notifications about the upcoming expiry date of the certificates in the Teradata Viewpoint key store. The Configure Alerts maintains a list of certificate expiry alerts. You can add new alerts, and edit or delete existing alerts. The Configure Alerts shows the alert name, status, severity, and the certificate name for which you have configured the alert.
By default, the Viewpoint system checks the enabled alerts everyday at 12 AM. If the set criteria of any of the alert satisfies, a notification triggers.
In the /opt/teradata/viewpoint/dcs/config/dcs.properties, the certalert.enabled is to enable or disable the system check for expiry alert, and the certalert.schedule is to modify the system check timing and frequency. Only a server administrator can modify the values of these parameters.
