No Data in analytic or log graph on NSX Advanced Load Balancer UI indicates that a particular event or entity has no data to display.

In the below screenshot, No Data is observed for a section of the log chart for a virtual service.



The following could be one of the reasons for NSX Advanced Load Balancer UI to display No Data in the log charts or the log graphs.

  • NSX Advanced Load Balancer upgrade process is in progress.

  • NSX Advanced Load Balancer Service Engine is overloaded and is not able to send metrics to NSX Advanced Load Balancer Controller to analyze the data.

  • NSX Advanced Load Balancer Controller is slow in processing data.

  • There is no valid request to define the data (for example, latency).
