Other Requirements and Considerations

  • The maximum time skew between the platform nodes has to be lesser than 30 seconds.

  • The availability of the NTP service is critical to system operations. Ensure that you do not reboot the platform node or the collector node when the NTP service is not available.

  • vRealize Network Insight services crashes and does not recover automatically when the existing compute resources are used up by the other processes on the platform. If the services fail to recover, reboot the platform node.

Supported Browser

  • Google Chrome or Mozilla Firefox Web browser
