Application table

If you click an ESX cluster in the ESX cluster/host table, or in the inventory view of the VMware vSphere Client, then the list of applications running in that ESX cluster appears in the application table of the dashboard.

If you click an ESX host (an ESX server that is not part of an ESX cluster) in the ESX cluster/host table, then the list of applications that are configured on systems hosted by that ESX server appears. Note that this is the only route to navigate to such applications through the dashboard

The following table lists each column in the application table and its description:

Column

Description

Applications

Indicates the application name.

Service Groups

Indicates the group of critical application components that VCS uses to determine the health of a monitored application. Service group is a VCS term. The equivalent term in Veritas High Availability terminology is "component group".

VCS may use more than one service group to monitor a complex application. The dashboard displays each service group of such an application as a separate instance of that application.

Status

This column indicates the effective status of an application in a VCS cluster. It does not indicate the state of the application on per member system. For example, in a two-system cluster, if the application has faulted on one system but has failed over to another system, then this column states the state of the application as Online.

Indicates one of the following states of an application:

  • Online

  • Offline

  • Faulted

  • Partial

Note:

After you perform an administrative task such as starting or stopping an application, or entering or exiting maintenance mode, it takes a few seconds for the dashboard to reflect the revised status of the configured application.

Systems

Indicates the number of systems where the application is configured for monitoring. To view more information about all such systems, click the (…) icon. The System table (drop-down) appears, listing the ESX host name of each configured system, the VM name (system name), and the status of the application on each system.

Alerts and description

Displays a triangular alert icon (!) and describes the reason for the alert. This column displays alerts in two cases: a). If the application status record is stale; b). If the application has faulted on a system.

For stale records, the column includes the timestamp of the last received health record. In case of application fault, the column provides details of the system where the fault occurred.
