View the statistics of a virtual server

To evaluate the performance of virtual servers or to troubleshoot problems, you can display details of the virtual servers configured on the NetScaler appliance. You can display a summary of statistics for all the virtual servers. You can also specify the name of a virtual server to display the statistics only for that virtual server. You can display the following details:
  • Name
  • IP address
  • Port
  • Protocol
  • State of the virtual server
  • Rate of requests received
  • Rate of hits

To display a summary of the statistics for all the virtual servers currently configured on the NetScaler, or for a single virtual server, at the command prompt, type:
