When an Exalate error has raised a notification will be sent to the jira-administrators group. It means that all administrators that are in the jira-administrators group get an email notification.
For an admin, working and doing the follow-up on the Exalate it's really helpful. However, not all JIRA administrators are working with the Exalate, so they don't need to get these emails.
You can choose which users should get the notification of the Exalate error.
- Create a new Jira users group (exalate-administrators) containing the users who should be notified in case of the Exalate error.
- Configure notifications to be sent to the exalate-administrators group (the one you've just configured).
