An opt-in node status notification service is available for Caviness users. This service sends an email notification when any nodes in your workgroup transition between two of the following states:

• offline: down and not reachable.
• online: up and reachable, but queues are disabled.
• accepting-jobs: up, reachable and queues are enabled.

The service currently checks nodes' statuses at the top of every hour and delivers email notifications at the bottom of the hour. If you opt-in and any of your workgroup's nodes have changed state, you will receive ONE email message detailing the status changes.

To opt-in the node status notification service for your workgroup(s), send an e-mail to consult@udel.edu with subject="Node notification opt-in Caviness" and make the first line of the message body be

    Type=Cluster
