I haven't seen that type of feature yet but you can selectively send different types of alerts to different places. For key hardware alerts, like switches or security appliances going down, we add our phones text/email address to the alert so we get text messages in addition to the e-mail alert. This helps us avoid having critical stuff get lost in the onslaught of alerts.
