When an alert subscription is configured, the alert notifies the specified user or group of users by e-mail message when the alert fires.
You can configure an alert subscription to send e-mail notifications when the alert reaches a severity of warning, a severity of critical, or both.
You can also configure an alert subscription to escalate after a specified period of time. If the alert is not resolved within the time allowed, it e-mails an escalation message to the user or group whose address you provide. Sybase recommends that if you configure alert subscriptions to escalate, you do so only for the most urgent alerts, those with a severity of critical.
