netscaler_servicegroup - Manage service group configuration in Netscaler

New in version 2.4.

Synopsis

  • Manage service group configuration in Netscaler.
  • This module is intended to run either on the ansible control node or a bastion (jumpserver) with access to the actual netscaler instance.

Requirements (on host that executes module)

  • nitro python sdk
