Step 4: Working with the Server Network Diagram

On a server details page, the server network diagram is displayed if the neighboring server count is less than the allowed maximum. For larger networks, neighboring servers are displayed in a table. The selected server for which details are displayed is shown in orange while rest of the servers are gray. Each arrow indicates the source and destination of a network connection. The diagram initially displays the first-order neighbors of the selected server. Choosing the + icon extends the view to additional neighbors.

The following screenshot shows the server network diagram in its initial state for the selected server.

Hover over an element of the diagram to view additional information about it. Hovering over a server node displays basic system information, and hovering over a connection displays the destination port and network protocol.

The following screenshot shows the detailed information displayed for a server node.

Choose a server node to select it. Selected nodes are displayed with green check mark in nodes. Multiple nodes can be selected and grouped as an application. Open a server node to view the details for that server.

In the following screenshot, two neighboring server nodes have been selected.

Application Discovery Service supports grouping individual servers into applications. An application is a higher-level group of interdependent servers that implement a solution together. On the Servers page, you can select up to 10 discovered servers at a time and group them into a new or existing application. From a server detail page, you can manipulate the diagram of neighboring servers to create or add to an application.

To group servers as applications

  1. In the navigation menu, choose Servers.

  2. In the table, select the checkboxes of the servers to group as an application and choose Group as application.

  3. In the Group as application window, choose Group as a new application. Provide values for Application name and (optional) Application description.

  4. Choose Save. Note that table entries for the grouped servers now display the name of the new application in the Applications field.

To add servers to an existing application

  1. In the navigation menu, choose Servers.

  2. In the table, select the checkboxes of the servers to add to an application.

  3. Choose Group as application, Add to an existing application and select an application from the list.

  4. Choose Save. Note that table entries for the selected servers now display the name of the existing application in the Applications field.

To group servers in a new application using the interactive diagram

  1. In the navigation menu, choose Servers.

  2. In the interactive diagram, select the server that owns the detail page, and then select one or more neighboring servers. In the following screenshot, one additional server has been selected.

  3. Choose Group as application, Group as a new application.

  4. Provide values for Application name and (optional) Application description.

  5. Choose Save. In the following example screenshot, note that the new application (NewApp, in this example) is now listed in the Applications list.

To add a server to an existing application from the interactive diagram

  1. In the navigation menu, choose Servers.

  2. In the interactive diagram, select a server to add to an existing application. In the following example screenshot, server ip-10-0-0-33, has been selected.

  3. Choose Group as application, Add to an existing application.

  4. In the Group as application window, choose an application from the list.

  5. Choose Save.

  6. Choose Show table of all connections. Note that the Applications value for the selected server confirms that it is now a member of the application, along with the original members.

To remove multiple servers from an application

  1. In the navigation menu, choose Servers.

  2. In the table, select the checkboxes of the servers to remove from an application where they have shared membership.

  3. Choose Actions, Remove server from application.

  4. In the Remove server from application window, choose the application from which to remove the server.

  5. Choose Remove. Note that the Applications field no longer includes the selected servers.

To remove a server using the interactive diagram

  1. In the navigation menu, choose Servers.

  2. In the table of servers, for Server ID, select the server to remove from an application.

  3. In the interactive diagram, choose Actions, Remove server from application.

  4. In the Remove server from application window,choose the application from which to remove the server.

  5. Choose Remove. Note that the removed application no longer appears in the Applications list.
