When configuring an application segment, you must identify the server group that contains the servers hosting the defined applications.

There are two types of server groups you can configure:

• You can create a server group and manually add servers you've explicitly defined.
• You can create a server group with dynamic server discovery enabled so that the appropriate servers for your applications are discovered as users request them. If you use this method, you do not need to manually define each server in the server group.

When you configure server groups, only group servers that are capable of hosting the same applications. To learn more, see Configuring Server Groups.

You also have the option to configure server groups when configuring a new application segment.

About the Server Groups Page

On the Server Groups page (Policies > Access Control > Private Control > Server Groups), you can do the following:

1. View a list of applied filters available from the current and previous user sessions. Applied filters must be saved to the user session first before they can be viewed. Use the drop-down menu to select the applied filters to view. To learn more, see Using Tables.
2. Hide the filters on the page by clicking Hide Filters. Click Show Filters to display the filters.
3. Refresh the Server Groups page to reflect the most current information.
4. Filter the information that appears in the table. By default, no filters are applied. You can also save applied filters to your preferences so that they're visible in future user sessions. To learn more, see Using Tables.
5. Add a new server group, then add servers you've explicitly defined, or enable dynamic server discovery so that the appropriate servers for your applications are discovered as users request them.
6. Expand all of the rows in the table to see more information about each server group.
7. View a list of all server groups that were defined for your organization. For each server group, you can see the following:
   • Name: The server group name.
   • Status: Indicates that the server group is enabled or disabled.
   • Dynamic Server Discovery: Indicates that the server group has dynamic server discovery enabled or disabled.
   • App Connector Groups: The App Connector groups that have access to the data center or virtual private cloud (VPC) that contains the servers in this server group. Expand a server group in the table to see the names of the App Connector groups that are linked to the server group. To learn more, see About App Connector Groups.

If a server group is missing the required settings, then the yellow Caution icon () appears next to the name within the table. Edit the server group to resolve the configuration issues.

8. View a configuration graph of connected objects.
9. Edit an existing server group.

10. Delete a server group.

    If a server group is configured using Zscaler Deception, then the edit and delete options are unavailable.

11. Modify the columns displayed in the table.
12. Display more rows or a different page of the table.
