The feature known as Pulse is enabled by default and sends cluster status information automatically to Nutanix customer support. After you have completed initial setup, created a cluster, and opened ports 80 or 8443 in your firewall, AOS sends a Pulse message from each cluster once every 24 hours. Each message includes cluster configuration and health status that can be used by Nutanix Support to address any cluster operation issues.
AOS can also send automatic alert email notifications to Nutanix Support by default through ports 80 or 8443. Like Pulse, any configured firewall must have these ports open. Some examples of conditions that will automatically generate a proactive case with Nutanix support with a Priority Level P4.

You can optionally use your own SMTP server to send Pulse and alert notifications. If you do not or cannot configure an SMTP server, another option is to implement an HTTP proxy as part of your overall support scheme.
While the best thing is never to a get a call, 2nd best is not waiting in line to open a ticket. Have a great week!
