DNS Mode

A DNS lookup is performed to resolve the DNS name of the GTM using the domain name or IP address of an application. An Inframap is created after successful completion of discovering the following objects:
  • The Wide IPs, virtual servers, end servers, pools, and pool members associated with the application are retrieved from the database.
  • The virtual server retrieves the certificate details using profiles.
  • The virtual IP address retrieves the NAT rules, ingress, and egress security policies associated with the source and destination IP port.
  • The pool member IP address retrieves the certificate details, NAT rules, ingress, and egress firewall security policies at the end server level.

To discover an application infrastructure based on DNS:

  1. Click and select AppVision > Application.
    The Application screen opens with the Inframap tab selected by default.
  2. Click in the command bar.
    The Discovery screen that pops up displays all the pre-configured quick discovery modes.
  3. Click beside the DNS discovery mode.
  4. On the request form, enter a name or IP address for the application or a URL to discover the modules associated with the application.
  5. In the Port field, enter the port number for the application you want to discover.
  6. Click Discover to trigger the discovery.
  7. A new Request ID is created. The request details along with their status are displayed in the Discovery status tab.
  8. Click the Request ID to view the work order tasks or phases of the corresponding request are listed in a tree-view. You can click each task to view its details.
    Wherever applicable, all the logs related to the selected task are displayed in the Logs pane at the bottom of the screen.
