Citrix High Availability XML Service Test

The Citrix XML service is responsible for communications between the Web Interface component and the XenDesktop site. The XML Service authenticates users, provides a list of available virtual desktops, and generates the information to allow the end-point to make a connection to the virtual desktop. To understand the load handled by the XML service, proactively determine probable delays in the delivery of the XML service, and to isolate the exact XML transaction that is causing the slowdown, you can use this test.

This test is disabled by default. To enable the test, follow the Agents -> Tests -> Enable/Disable menu sequence, select Citrix Cloud Connector as the Component type, select this test from the Disabled Tests list, and click the < button to enable it.

Parameter Description

Test Period

How often should the test be executed.


The IP address of the host for which this test is to be configured.


Refers to the port at which the specified host listens to.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Average transaction time

Indicates the time taken by this XML transaction to complete.


Ideally, the value of this measure should be low. A high value indicates that a particular XML transaction is taking too much time for execution; this can adversely impact the user experience with the broker. 

Concurrent transactions

Indicates the number of concurrent transactions being processed.


These measures are good indicators of the processing ability of the XML service.


Indicates the rate at which this transaction was processed by the XML service.
