What's New

Here are the key features and capabilities of vRealize Network Insight 6.5:

VMware NSX-T Monitoring and Troubleshooting

  • Supports VMware NSX Advanced Load Balancer for VMs in the vRealize Network Insight on-premises and VMware Cloud deployments.
  • Introduces built-in and enforced protection mechanism to disable NetFlow collection on Distributed Virtual Port groups where VMware NSX-T edges are connected.

Network Assurance and Verification

Platform Enhancements


Product Upgrade

The supported upgrade path is available at https://interopmatrix.vmware.com/#/Upgrade?productId=285.

Refer to the Upgrading vRealize Network Insight section for more information on the upgrade procedure.


For additional information about new features, see the vRealize Network Insight documentation.

Note: As you use the vRealize Network Insight documentation, we want you to know that we value inclusion at VMware. To foster this principle within our customers, partners, and internal communities, we have updated some terminology in our documentation.

VMware Product Compatibility

The VMware Product Interoperability Matrix provides details about the compatibility of vRealize Network Insight with other VMware products.

VMware MIB Files

For MIB information, see Determining the MIB module listing, name, and type of an SNMP OID. You can download the SNMP MIB module file from the VMware Knowledge Base Article: 1013445.

Resolved Issues

  • While planning for micro segmentation, flow data is intermittently missing for some applications.

  • vRealize Network Insight is unable to collect data from the VMware NSX-T Manager and shows the 'No Data being received' alert.

  • VMware vCenter and VMware NSX-T data sources data collections fail due to the CollectorState looping issue.

  • When latency collection is enabled, vRealize Network Insight shows the 'Could not get response for /api/v1/transport-zones/62f9eac3-1a82-4e38-aeed-493a5c87dd00, status 400' error while collecting data from the data sources.

  • Kubernetes clusters managed by Tanzu Kubernetes Grid Integrated Edition are unreachable from the collector VM.

  • Unable to login to vRealize Network Insight as the login credentials are not accepted.

  • vRealize Network Insight shows the 'Realtime stream processing has failed' error while navigating the interface.

  • vRealize Network Insight does not show a VM-VM path for Check Point data source due to the 'unknown path' error.

  • Unable to login using LDAP after configuring LDAP in vRealize Network Insight 6.2.

  • Data collection from Tanzu Kubernetes Grid Integrated Edition data sources shows a false 'Invalid data source config' error.

  • vRealize Network Insight interface lags when using queries pre-set values for VeloCloud Edges and unable to navigate to any VeloCloud Edges entity pages.

  • Unable to receive email notifications after configuring alerts and notifications.

  • When HSRP/VRRP interface on the Active device goes down or is administratively down, the HSRP/VRRP Configuration Error intent does not raise an alert for the violation.

  • False Loop Detection Intent alerts are triggered when a link is incorrectly inferred between two interfaces where MAC address table entries associated with them contain the same MAC address but are associated with different VLANs.

  • Under the Status column of the Application dashboard, some applications saved from the Flows application discovery tab show the error 'Unable to update application'. This is due to an issue in the data processing layer and this error does not affect the applications. You can use applications showing this error for planning, micro-segmentation, and troubleshooting without any issues.

  • If a data source is incorrectly shut down or restarted, then the corresponding thread pool is discarded, and this does not schedule new processes like collection of metrics.

    Restart the collector service to free the unused threads and reallocate them.

  • Updates in the organization name done using the VMware Cloud Services Portal are not reflected in Fractal API response, as there is no data synchronization mechanism between the VMware Cloud Services Portal and the Fractal API. Fractal API returns the old organization name causing an inconsistency between the vRealize Network Insight and the VMware Cloud Services Portal organization name.

  • If UAA as OpenID Connect (OIDC) provider is enabled in VMware Tanzu Kubernetes Grid Integrated Edition, an 'Invalid data source config' error is shown in the VMware Tanzu Kubernetes Grid Integrated Edition data source.

Known Issues

  • [NEW] If the VLAN interfaces of Cisco ACI switches are used as source or destination, the path search in Network Map does not show any results.

  • [NEW] Path search in Network Map does not return any results if Check Point VRRP virtual IP is used as the source address.

  • [NEW] Incorrect MTU is shown in UCS vEthernet interfaces.

  • [NEW] Unable to draw the network path as the Branch to Branch VPN configuration is disabled for the HUB VMware SD-WAN edge in VeloCloud Orchestrator.

  • [NEW] Cisco ACI switches do not supported Port Channel Member Mismatch intent.

  • [NEW] vRealize Network Insight recommends configuring unique FQDN hostnames on host entities (like UCS Blades or servers) for proper interpretation of underlying host entities. Absence of unique FQDN hostnames may lead to incorrect association of VMs to underlying similar hostnames.

  • [NEW] VMware NSX-T data source shows the 'Data collection failed due to an error' message if there are any entities with Japanese characters in them.
