Hey All,
Not to drag up an old post but I am having the exact same behavior as posted above. I have an alert that doesn't send an e-mail, and it is a volume related alert as well. The test alert functions correctly and the alert comes through. Here is a screen shot of my triggers:
The reset conditions are set to just when trigger are no longer set, time of day is set to default, no suppression, and only one trigger action which is to send an e-mail. The SMTP settings are identical to other alerts that work correctly.
Anyone else have this happen? It looks like it only applies to the "Type of Property to Monitor: Volume", as all my other alerts work.
