Monitoring an LLB Setup

After the configuration is up and running, you should view the statistics for each service and virtual server to check for possible problems.

Viewing 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 Citrix ADC appliance. You can display a summary of statistics for all the virtual servers, or you can 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 virtual server statistics by using the command line interface

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

stat lb vserver \-detail] [<name\>]

Example:

``` pre codeblock

stat lb vserver -detail Virtual Server(s) Summary vsvrIP port Protocol State Req/s Hits/s One * 80 HTTP UP 5/s 0/s Two * 0 TCP DOWN 0/s 0/s Three * 2598 TCP DOWN 0/s 0/s dnsVirtualNS 10.102.29.90 53 DNS DOWN 0/s 0/s BRVSERV 10.10.1.1 80 HTTP DOWN 0/s 0/s LBVIP 10.102.29.66 80 HTTP UP 0/s 0/s Done


### To display virtual server statistics by using the configuration utility

1.  Navigate to Traffic Management \> Load Balancing \> Virtual Servers \> Statistics.
2.  If you want to display the statistics for only one virtual server, in the details pane, select the virtual server, and click Statistics.

## Viewing the Statistics of a Service

You can view the rate of requests, responses, request bytes, response bytes, current client connections, requests in surge queue, current server connections, and so forth using the service statistics.

``` pre codeblock
stat service Service-HTTP-1
