vRealize Network Insight contains a list of predefined system events (system problems and system changes) for which you can receive automated email notifications every four hours, which you an modify.

You can view the list of notifications on the Settings > System Notifications page.

If you have not configured any e-mail or SNMP notifications for an event, you see an alerting message on the home page that reminds and allows you to define notifications. You can click Enable Notifications on the alert message to directly navigate to the System Events page and subscribe notifications for the preferred events.

To disable the reminder, select the Don't show this message again option. The alert message will not appear for that particular user. To define notifications later, navigate to Settings > Events.
