Notification policy for DPA alerts

When you create an alert in DPA, you can accept the default notification policy or apply a different policy to that alert. The notification policy determines when the alert is triggered. The following sections describe each policy.

Notify when level not visited since normal

A notification is sent if the alert status is not Normal and the alert has not been in this status since the last time the status was Normal. If the alert returns the same status for multiple polling periods without returning to Normal, you are notified only once for each status. For example:

Execution Interval	Alert Level	Notification Sent?
1	Normal	No
2	Medium	Yes
3	High	Yes
4	High	No (this alert level was returned previously)
5	Medium	No (this alert level was returned previously)
6	Low	Yes
7	Normal	No
8	Low	Yes

This is the default policy, but a DPA administrator can change the default policy in Advanced Options.

Notify when level changes and is not normal

A notification is sent if the alert status is not Normal and has changed since the previous execution interval. You are notified each time the level changes, but only once for each change. For example:

Execution Interval	Alert Level	Notification Sent?
1	Normal	No
2	Medium	Yes
3	High	Yes
4	High	No (the alert status has not changed)
5	Medium	Yes
6	Low	Yes
7	Normal	No
8	Low	Yes

Notify when level is not normal

A notification is sent if the alert status is not Normal, regardless of the alert's previous status. For example:

Execution Interval	Alert Level	Notification Sent?
1	Normal	No
2	Medium	Yes
3	High	Yes
4	High	Yes
5	Medium	Yes
6	Low	Yes
7	Normal	No
8	Low	Yes
