Citrix Farm Connections Test

This test tracks the connectivity of the different servers in the zone with the central ZDC of the zone. Every time the test executes, it sends ICA packets to a server and measures the server availability and response time. This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick Citrix ZDC as the Component type, Performance as the Test type, choose the test from the disabled tests list, and click on the >> button to move the test to the ENABLED TESTS list. Finally, click the Update button.

Target of the test : A Citrix ZDC

Agent deploying the test : An external agent

Outputs of the test : One set of results for the ZDC being monitored

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Farm connection availability

Indicates the availability of the server.


A value of 100 % indicates that the Citrix server is responding to requests. 0 indicates that the server is not responding. A server might not respond if it is not up and running or if it is overloaded.

Packet loss to server

Indicates the percentage of packets sent that were replied by the server.


While 0 indicates that the server is responding to requests, any value greater than 0 could indicate that the server is not able to keep up with its current load.

Avg response time

Response time is the time from packet transmission to reception. Average response time measures the average value of the response time based on replies returned by the server.


Increase in the average response time indicates slow-down of the server and potential issues in handling user requests by the server.

Max response time

This is the maximum of response times based on replies returned by the server.


If this value is consistently different from the average response time, further investigation of other server metrics may be necessary.
