VMware NSX-T is designed to address the emerging application frameworks and architectures that have heterogeneous endpoints and technology stacks. In addition to vSphere, these environments may also include other hypervisors, containers, bare metal, and public clouds. vRealize Network Insight supports NSX-T deployments where the VMs are managed by vCenter.

Considerations

  • NSX-T 2.0, 2.2, and 2.3 versions are supported.

  • vRealize Network Insight supports only the NSX-T setups in which vCenter manages the ESXi hosts. Ensure that vCenter is added as Compute Manager in NSX-T.

    Note:

    Compute Managers should be added as data sources in vRealize Network Insight before adding NSX-T as a data source.

  • vRealize Network Insight supports NSGroups, NSX-T Firewall Rules, IPSets, NSX-T Logical Ports, NSX-T Logical Switches, and NSX-T distributed firewall IPFIX flows.

  • vRealize Network Insight supports both NSX-V and NSX-T deployments. When you use NSX in your queries, the results include both NSX-V and NSX-T entities. NSX Manager lists both NSX-V and NSX-T Managers. NSX Security Groups list both NSX-T and NSX-V security groups. If NSX-V or NSX-T is used instead of NSX, then only those entities are displayed. The same logic applies to the entities such as firewall rules, IPSets, and logical switches.

To Add an NSX-T Manager as a Data Source

Here are the prerequisites for adding an NSX-T Manager as a data source:

  • Before adding NSX - T, add at least one vCenter which is associated with NSX - T to vRealize Network Insight.

  • It is recommended that you add all the vCenters associated with NSX-T as data sources in vRealize Network Insight.

  • Ensure that there are no logical switches in the exclusion list in the Distributed Firewall (DFW). If there are any logical switches in this list, then the flows are not reported for any VMs attached to these logical switches.

To add an NSX-T Manager:

  1. On the Accounts and Data Source page under Settings, click Add Source.

  2. Under VMware Manager in the Select an Account or Data Type page, select VMware NSX-T Manager.

  3. Provide the user credentials. The user should be a local user with the audit level permissions.

  4. Select Enable IPFIX to update the IPFIX settings on NSX-T. By selecting this option, vRealize Network Insight receives DFW IPFIX flows from NSX-T. For more information on enabling IPFIX, see Enabling VMware NSX-T DFW IPFIX.

    Note:

    DFW IPFIX is not supported in the Standard Edition of NSX-T.
