The Alerts Overview dashboard provides the alerts page of vRealize Operations Manager. On this page, you can not only view the alerts triggered on your vRealize Operations Manager federation instance, but also view the alerts triggered in your child vRealize Operations Manager instances.
The overview page includes all the alerts triggered on the vRealize Operations Manager instance and is not dependent on the objects you are monitoring from the child vRealize Operations Manager instance.
This page can help your NOC teams to have a single pane for all the alerts across your environments. To view the details of a specific alert, click on that alert to get directed to the child vRealize Operations Manager instance where the alert was originally triggered for troubleshooting purposes.
