Setting up for Email or Web Server Alert Notification - AWS Elemental Delta

This is version 2.3 of the AWS Elemental Delta documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Delta Documentation.

Setting up for Email or Web Server Alert Notification

You can set up AWS Elemental Delta to notify you when alerts occur. The notification can be an email or an HTTP POST to a web server.

AWS Elemental use open relay to send email notifications. Before subscribing to notifications, make sure that your network allows receipt of open relay email. To receive messages from an AWS Elemental system in a network that does not allow receipt of open relay email, configure a sendmail relay with another mail server, as described in Configuring Sendmail Relay Server.

Warning

If you subscribe to email notifications in a network that does not allow open relay and you do not relay the messages, the generated messages collect on the system hard drive, eventually fill the partition, and cause disk alert errors.

To subscribe to all alerts generated by the cluster

  1. Go to Settings, which defaults to the General tab.

  2. Complete the dialog by selecting settings from the table that follows.
