NSX Intelligence 3.2

NSX Intelligence Platform and Form Factor Changes

  • New Scale-out Architecture – To achieve higher scale and additional functionality, NSX Intelligence now runs on the NSX Application Platform. Starting with the 3.2 release, NSX Intelligence is no longer offered as an independent appliance (OVA) installation. Please note that since the NSX Application Platform runs on Kubernetes, a Kubernetes cluster must be already deployed and available prior to the installation of the NSX Application Platform and NSX Intelligence. See the following documentation for more information.
  • NSX Intelligence integration with vSphere Lifecycle Manager – You can now run NSX Intelligence with ESX clusters that are vSphere Lifecycle Manager enabled.
  • NSX Intelligence Data Collection Settings – Provides the ability for you to selectively enable NSX Intelligence to collect data on a subset of ESXi hosts or clusters of hosts, which aids in scale management and license compliance. See Configure NSX Intelligence Settings for details.

NSX Intelligence Visualizations

  • Workload View Enhancements:
    • Details about User Logout Time and VM Tools Version are added.
    • Shows the latest group information for a unique flow.
    • Shows aggregated flow attributes (Source and Destination IP addresses, Users, Process, FQDN, and more details) about a flow when you select Flow Details from a node’s contextual menu.
  • Canvas View Enhancements: Enhances the Public IPs Group to specify an exact list of public IP addresses that are communicating to NSX objects in your NSX-T Data Center.
  • Performance: Improved performance when loading the landing page views for the compute and group views.
