  • When polling for Security Tags in vRealize Network Insight, the result will max out at 1024 <sent query for more info>

  • In vRealize Network Insight, some Source IPs showing flows more than the defined flow limit.

  • On Platform appliance, when manually increasing VM limit through API, vRealize Network Insight does not reflect the increased VM capacity.

  • When you run a query for VM to VM path in vRealize Network Insight, the path is not visible for stretched layer 2 network.

  • The sub-interfaces on VRF for Cisco Nexus 7000/9000 are not supported.

  • vRealize Network Insight not working due to corrupt registration certificate.

Known Issues

  • [New] When you search for Kubernetes Nodes in vRealize Network Insight, the search result displays the list of Master Nodes for native kubernetes cluster and not for VMware PKS.

  • [New] In absence of a firewall rule on a VM, default connectivity strategy applies to a VM in VMC.
    In such a case, the firewall icon isn't present in VM-VM path on VMC side as we do not get enough information about the realization of the default rule from the VMC SDDC.

  • [New] If you are using the Firefox browser and viewing the NSX-T VM path Topology, after you expand the ECMP group, you do not see the collapse option to minimize the detail view.

  • [New] When you attempt to export a pinboard in which the pinboard name contains a Non-ASCII character, vRealize Network Insight shows the incorrect file name on the Export to PDF window.

  • [New] When the count of VMs associated to a firewall rule’s source or destination gets updated from a non-zero value to zero, and if you run firewall rule query with source VM or destination VM as a filter, it may give an incorrect result.

  • [New] When you add a filter in the query result, the count shown in the filter are approximate.

  • [ New] If OpenID Connect (OIDC) authenticator is used for PKS or Native Kubernetes Cluster, then contact VMware Support.

  • [New] vRealize Network Insight does not detach the NSX-T logical ports from the unhealthy pods or nodes.

  • When you set the home page from My Preferences, it requires a page refresh to reflect that information in UI.

  • After upgrade, the system takes about two to three hours to settle down and to reflect the correct data in the UI.

  • When you attempt to add a Cisco ASA data source, you see a message to contact support with the following error: 

    Message missing required fields: vendorId
  • vRealize Network Insight reports proxy communication failure when the postgres service on the proxy server does not start automatically and the CollectorMain javaservice keeps restarting.

  • If the disk is full on a zookeeper leader node, command states that zookeeper is healthy while it is actually unhealthy. To fix this issue, restart zookeeper.

  • The auto-refresh counter restarts and keeps showing incorrect data even though auto-refresh is paused.

  • vRealize Network Insight may not be able to detect an out-of-sync system clock sometimes. If the clock is not in sync with NTP, some services may become unhealthy or stop working.

  • The bundle upload or extraction and the subsequent upgrade steps may fail if there is insufficient space in the /tmp directory. For single-click offline upgrade and online upgrade, ensure that there is a certain amount of disk space available in the /tmp directory.

  • The disk may run out of space for the vRealize Network Insight Platform VM. In large environments, the partition /var may become full and additional storage may be needed. See KB article 53550 for instructions on how to increase disk space.

  • The vRealize Network UI is not available when the partition /var is more than 85% full in the Platform VM. For validation and fix, contact VMware support.

  • An unwanted default rule is applied to certain NSX IPFIX flows. This is because sometimes, NSX IPFIX reports reverse packet in which client and server are flipped and the firewall rule is applied as per the flipped source and destination IP.

  • The Export to CSV feature for the flow data takes more than 30 minutes for 180,000 flows when all the fields are selected.

  • The Export to PDF feature for the PCI dashboard has the following known issues:

    • The changes that you make in the NetFlow flow diagram dashboard are not visible in the PDF.
    • For a particular widget, the number of properties that are exported as PDF is more than the number of properties that are actually selected in that widget.
    • The non-ASCII characters are not being exported correctly to the PDF. The workaround for this issue is to run the sudo apt-get install fonts-wqy-zenhei command on the vRealize Network Insight server to install the additional fonts.​
    • The metric properties are not exported in the PDF.
  • When you create a logical subnet or logical router, a new edge VM is dynamically created to serve this request. The events for this kind of VM are shown.

  • If issues such as upload failure or UI failure come up while performing the centralized upgrade, please contact VMware support.

  • The Plan Security page for the last 2 days takes around 3 minutes to load. A higher response time is seen while executing queries for about 24 hours after migration of a data source between collectors. This is because the same flows are reported, opened, and closed from two different collectors within a span of 24 hours. It leads to multiple versions created for the same flows.

  • Sometimes, the Export to CSV feature fails with the 502 error in the browser. The workaround is to retry the operation.

  • vRealize Network Insight does not support rollback or product downgrade. It is recommended that you take a backup.

  • The datastore metrics of a VM are not shown on vRealize Network Insight if it is hosted on vSAN Datastore.

  • If the vCenter and the associated NSX manager data sources are not attached to the same proxy server, you will not see the denied flows (when NSX IPFIX is enabled) and the Applied Firewall Rule will be missing in some flows.

  • The NAT rules on the NSX Edge version 5.5 or the previous versions are not supported.

  • The firewall rule section of the PCI Compliance dashboard may show incorrect rules if the selected scope is a nested security group in NSX or an application when multiple NSX managers are added as a data source.

  • In the Applied To grouping criteria, the NSX edge is not supported.

  • The platform cluster does not support the high availability configuration. All the platform nodes need to be up and running for the cluster to work at optimal performance levels.

  • The recommended firewall rules support only global rules creation. The creation of universal rules is not supported.

  • The plan topology widget has options to select all flows, all protected flows, and so on. The flows that are solely captured from VDS and not from NSX IPFIX only show up when the all flows option is selected because their protection status is classified as unknown not as protected or unprotected

  • The Export as CSV option is not supported for advanced searches that use group by, sum, max, and min functionality.

  • Some events such as Host network control plane mismatch are not raised if the datacenter is not at the top level and is located inside a folder in vCenter.

  • The product update notifications are supported only for the single-platform node deployment that is connected to Internet.

  • The support bundle creation on a medium sized system can take in excess of fifteen minutes.

  • There is a known issue in the list view for events search where sometimes facet counts are incorrect upon selection and no events are shown.

  • vRealize Network Insight shows the older version after the upgrade. Once the product upgrade is complete, refresh the browser after clearing the browser cache.

  • Upon the expiry of the Evaluation license, the data providers are disabled and they stop collecting data. After renewing the license, the data providers must be enabled again from the UI to start data collection.

  • To use Gmail® server as the choice of e-mail server, additional configuration settings as listed on Google Support are required.

  • After you remove a data source from the system, you can add the same data provider back only after two or more hours.
