Managing subscriptions

Citrix Application Delivery Management (Citrix ADM) requires a verified license to manage and monitor Citrix ADC instances, Citrix Gateway instances, and third party load balancers.

You can manage and monitor any number of instances when you are on the trial period or when you have subscribed to a valid license. However, you can manage the discovered applications on the App Dashboard, view analytics data, and monitor network functions and network reports only for the number of virtual servers for which you have purchased licenses. During trial period, you can monitor only ten virtual servers or applications.

With each installed license, you receive a limited amount of data and capacity to manage certain virtual servers. However, you can also purchase and apply data-only licenses to top up your data storage.

Note

After the trial period expires, you must purchase a valid license to continue to use any feature in Citrix ADM.

For information and instructions about buying and upgrading your Citrix ADM licenses, see https://www.citrix.com/products/citrix-cloud/subscriptions.html.

The following table lists the Citrix licenses that are required to use some of the Citrix ADM features.

Manage subscriptions for third-party virtual servers

You can manage and monitor any number of HAProxy hosts when you are on the trial period or when you have subscribed to a valid license. However, you can manage the discovered applications on the HAProxy App Dashboard, view analytics data, and monitor network functions only for the number of third party virtual servers for which you have purchased licenses. During trial period, you can monitor only ten third party virtual servers or applications.

Note

In this document, the third-party virtual server refers to the HAProxy frontend.

View the subscription details

You can view the licenses installed on your Citrix ADM by navigating to Account > Subscriptions. You can also view the license summary such as the type of license subscribed to, the entitled data subscription and consumed data subscription, and the allowed and managed virtual servers and third party virtual servers in the Subscription Summary section.

Select the virtual servers to manage

You can select the virtual servers or third party virtual servers you want to manage and monitor through Citrix ADM.

Points to note:

• By default, Citrix ADM automatically licenses the virtual servers randomly after each virtual server poll cycle.
• If the total number of virtual servers discovered in your Citrix ADM is lower than the number of installed virtual server licenses, Citrix ADM, by default, licenses all the virtual servers.

To select the virtual servers manually, or to restrict licensing to limited virtual servers, you have to first disable auto licensing the virtual servers, and then select the virtual servers you want to manage.

To select virtual servers for licensing:

1. Log on to Citrix ADM using a supported web browser.

2. Navigate to Settings > Subscriptions.

   The dashboard displays the virtual server licenses available, the managed virtual servers along with the virtual server type, and license expiry information.

3. In Licensed Virtual Servers, disable Auto-select Virtual Servers.

   

4. Click Click to select.

5. In the License Virtual Servers page, select the type of virtual servers by clicking the relevant tab.

   

6. Select the virtual servers to be licensed from the available list and click Apply Advanced License.

   Note

   The License Virtual Servers page also displays an option. All Virtual Servers**, that lists all virtual servers irrespective of the fact that they are load balancing, content switching or any other type of virtual servers. You can select the virtual servers required from this view and apply licenses to them.

7. Click Next to move to the other virtual servers’ tab.

8. Click Finish to license the selected virtual servers.

To select third party virtual servers for licensing:

1. Log on to Citrix ADM using a supported web browser.

2. Navigate to Settings > Subscriptions.

   The dashboard displays the virtual server licenses available, the managed virtual servers along with the virtual server type, and license expiry information.

3. In Managed Third Party Virtual Servers, disable Auto-select Third Party Virtual Servers.

   

4. Click Click to select.

5. In the Choose TP Virtual Servers screen, select the type of virtual servers by clicking the relevant tab.

   

6. Select the third party virtual servers to be licensed from the available list.

7. Click Finish to license the selected third party virtual servers.

View the licensed virtual servers

After the licenses are applied to the virtual servers, you can view the licensed virtual servers or third-party virtual servers from the Subscriptions page. To view the licensed virtual servers, navigate to Settings > Subscriptions and click the virtual server type in the Total Licensed section in the Licensed Virtual Servers or Licensed Third Party Virtual Servers pane.

The licensed virtual servers are displayed on the respective page.

Configure auto license support for non-addressable virtual servers

Citrix ADM, by default, does not automatically apply licenses to non-addressable virtual servers. For licensing non-addressable virtual servers, you must disable the auto-license option and manually select the non-addressable virtual servers. This increases your effort to manually select the non-addressable servers initially when you apply the licenses. You also need to manually select the new non-addressable virtual servers whenever they are added to your network.

Citrix ADM provides a new option in Citrix ADM under Account > Subscriptions. That is, the new option Auto-select nonaddressable Virtual Servers. Enabling this option now allows you to explicitly specify that the licensing should include non-addressable virtual servers also.

Note:

• Citrix ADM, by default, still does not auto select non-addressable virtual servers for licensing.

• Application analytics (App Dashboard) is the only analytics supported currently on licensed non-addressable virtual servers.

View expiry checks for virtual server subscriptions

You can view the status of installed licenses with the expiry and the allowed storage limit to the licenses in Citrix ADM.

To view the status of the licenses:

1. Navigate to Account > Subscriptions.

2. In the Entitlements section, you can view the details of licensed virtual servers and the days to expiry:

   • Advanced License: Number of advanced licenses available.
   • Entitled Third Party Virtual Servers: Number of third party virtual servers you can manage with the license.
   • Entitled Storage: Storage limit of the license.

   • Days to Expiry: Number of days remaining before the license expiry.

     

View the type of analytics enabled on the virtual servers

After you enable AppFlow on the selected virtual servers, you can view the type of analytics enabled on the licensed virtual servers or third-party virtual servers from the Subscriptions page.

1. Navigate to Account > Subscriptions.

2. In the Total Licensed section, select the type of licensed virtual servers.

   

3. The licensed virtual servers page displays the list of licensed virtual servers. On this page, the AppFlow Logging column displays the type of analytics enabled on the virtual servers.
