Imagine you receive a few emails based on a schedule, and these messages are expected to come every day. You want a system that ensures scheduled messages come at their expected time and generate an alert if that does not happen. The Missed Email Alerts plugin is designed to monitor messages that fail to arrive.
The following video demonstrates how this plugin works.
You will have to create two alerts. Assume you receive the first email at 9 AM and the second around 3 PM. You want the alert window to be 15 minutes.
Create two alerts with similar configuration for Recipient, Sender, Subject but with a different schedules.
Let's assume the following scenario as an example.
You want to create a rule that will catch all three variations of the message.
Solution Create a Regular Expression with the following value:
(Backup ran|Backup failed).* Server01The regular expression you see above will match every email where the subject starts with Backup ran, or Backup failed and ends with Server01.
