Manage licensing and enable analytics on virtual servers

Note

  • By default, the Auto Licensed Virtual Servers option is enabled. You must ensure to have sufficient licenses to license the virtual servers. If you have limited licenses and want to license only the selective virtual servers based on your requirement, disable the Auto Licensed Virtual Servers option. Navigate to Settings > Licensing & Analytics Configuration and disable the Auto Licensed Virtual Servers option under Virtual Server License Allocation.

The process of enabling analytics is simplified. You can license the virtual server and enable analytics in a single workflow.

Navigate to Settings > Licensing & Analytics Configuration to:

  • View the Virtual Server Licence Summary

      Enabling analytics

      Note

      • If you select virtual servers that are not licensed, then NetScaler Console first licenses those virtual servers and then enables analytics

      • For admin partitions, only Web Insight is supported

      • For virtual servers such as Cache Redirection, Authentication, and GSLB, you cannot enable analytics. An error message is displayed.

After you click OK, NetScaler Console processes to enable analytics on the selected virtual servers.

Note

NetScaler Console uses NetScaler SNIP for Logstream and NSIP for IPFIX. If there is a firewall enabled between NetScaler agent and NetScaler instance, ensure you open the following port to enable NetScaler Console to collect AppFlow traffic:

Transport Mode Source IP Type Port
IPFIX NSIP UDP 4739
Logstream SNIP TCP 5557
