Administering application availability using Veritas High Availability dashboard

The Veritas High Availability dashboard is a consolidated graphic user interface that lets you administer application monitoring on systems in a VMware vCenter administered data center.

The dashboard is fully integrated with the VMware vSphere Web Client. The dashboard appears in the Veritas High Availability tab of the VMware vSphere Web Client. To view the dashboard, select a data center or an ESX cluster in the inventory, and then click the Veritas High Availability tab.

On the dashboard, you can view the aggregate health statistics for monitored applications across a data center. You can also drill down to an ESX cluster and view monitored applications running in that cluster.

Note:

The dashboard presents a unified view of monitored applications in a data center. It displays an application-centric view, not a product-centric view. If you have configured applications under more one Veritas High Availability product (VCS or ApplicationHA), then you cannot determine which application is under the control of which Veritas High Availability product. However, you can conclude that applications configured for failover are under VCS control. Applications configured for monitoring without a failover system may either be under VCS control or under ApplicationHA control.

To understand how to navigate across the dashboard:

See Understanding the dashboard work area.

You can drill down to an individual application and perform the following administrative actions:

  • Start application

  • Stop application

  • Enter maintenance mode

  • Exit maintenance mode

  • Switch application (to another system)

Apart from applications on systems running Cluster Server, the Veritas High Availability dashboard also displays applications running on Symantec ApplicationHA guests (versions 5.1 SP2 and later).

For more information on monitoring applications running on Symantec ApplicationHA, refer to Symantec ApplicationHA documentation.
