Application hosts

Edit online

The Application hosts menu displays a page with a table of connected hosts. The source types listed in the table are automatically filtered by the Data Resiliency Service to show only application hosts.

An application host represents a workload or software product that consumes storage from a storage system typically as one or more volumes. And the application host is typically what a backup system interacts with in order to make copies of the data used (created or updated) for that application. A connected application host includes application servers that contain data relevant to the data resiliency of that application host. These application hosts connect to Data Resiliency Service through a connection manager. Application hosts of the same type are grouped together to create recovery groups. Currently, application host type includes VMware vCenter servers only. For more information about supported sources and resources see in the Terminologies of Sources and resources table.

Note: The connection managers access point enables users to perform actions associated with API keys, connection managers (including update), and source management (including credentials). These actions can also be performed through the All Resources access point. The menus, buttons, and available actions are displayed based on the user’s permission level for these access points. Users will only see options corresponding to their assigned permissions. For more information see Access points.
A table on the Application hosts page shows the following information for the connected application hosts:
  • Name: Name of the connected application hosts.
  • Type: Type of the connected application hosts.
  • Connection managers: Name of the connection manager where the application host is registered. Click a connection manager to get the detailed information. For more information, see Connection managers details.
  • Last scan: Status of the last scan.
    Note: The last scan status of a application host can be Scanning, Failed, or Success. If the scan is failed this can have various reasons such as expired credentials, network error, or some other technical issue. You can click on the failed status and view the job details and the log summary in the side panel. Inside the side panel you can also click Download log summary button.
  • Last scan time: Time of the last scan attempt.
  • Duration: Duration of the last scan.
  • Credential: Credential to access the source.
You can use the following options to refine the list of connected hosts:
  • Search bar: To find an existing application host.
  • Filter icon: To filter the list by:
    • Status
    • Type
    • Connection manager
  • Settings icon: To edit the columns or reset to default columns.
Note:
You need to have at least the following authority for actions associated with connection manager:
  • Viewer: View all functions in the Data Resiliency Service.
  • Editor: View and update all functions in the Data Resiliency Service.
  • Administrator: View, create, update, and remove all functions in the Data Resiliency Service.
For more information, see Access points.

You can also add an application host by clicking the Add application host button, which is located next to the search bar. For more information, see Adding an application host.

You can click the overflow menu icon in a table row for the application host you are interested in to complete the following actions:
  • Edit application host: This drop-down option navigates you to the Edit source wizard. In the Edit source wizard, you can modify connection details and review the certificate details; select an existing credential or create a new credential. For more information, see Editing sources.
  • View credential: This drop-down option navigates you to the side panel to display credentials-related information. The information includes: Username, Last updated, Access type, and Description. Inside the side panel, click the Edit button to edit credentials. For more information, see Editing credentials.
  • Associate connection manager: This drop-down option navigates you to the Associate connection manager window. In the Associate connection manager window, you can select a connection manager from the list to associate it with the source.
  • Disassociate connection manager: This drop-down option navigates you to the Disassociate connection manager window. In the Disassociate connection manager window, you can select a connection manager from the list that you want to disassociate from the source. You must have two or more than connection managers already associated with the source to have Disassociate connection manager option in the overflow menu.
  • Rescan: You can click this drop-down option to rescan the connected source type. A notification message appears indicating that source is being scanned.
  • Remove: You can click this drop-down option to remove the source from the Data Resiliency Service. A removal confirmation message appears with a warning about the impact of the removal. For more information, see Removing sources.
