I created an Alert Storage Profile, an Alert Notification Profile, Groups, Contacts, Group-Contact assignment, etc. and believe the system is ready to send alerts. I have a Group defined with an Expression of ‘1’ which I believe should always evaluate to true. It is ‘Valid?’ whatever that means.
I added alerting to a memory tag, changed the value to generate an alert.
The alert shows up in the Alert Console, the Alert Summary, and the alert_log table but the email has not been received. I looked at the System Console, and the wrapper.txt, but could not find any mention that an email had been sent (or failed to send).
How do I prove that the email was sent? I need to know now, during setup, but also need to be able to prove that an email was queued (or not) if an alert is not received in the future and something bad happens.
Also, is there any “retry” strategy for email? If an alert is not accepted by the email server, is it resent" How do I know it was not accepted by the email server, so that I know to check Ignition, connectivity, and the email server?
