Citrix XML Access - Cloud Test

This verifies the interactions between the web interface, the XML service, and the IMA service. A typical web interface interaction is composed of the following:

  • Client device users utilize a Web browser to view the Log in page and enter their user credentials.
  • The Web Interface reads users' information and uses the Web Interface's classes to forward the information to the Citrix XML Service; this service can execute on the Web Interface or on each of the Presentation servers in a server farm. If this service executes on a XenApp server, then the designated server acts as a broker between the web interface server and the Presentation servers in a farm.
  • The Citrix XML Service then retrieves a list of applications from the servers that users can access. These applications comprise the user's application set. The Citrix XML Service retrieves the application set from the Independent Management Architecture (IMA) system and Program Neighborhood Service, respectively
  • The Citrix XML Service then returns the user's application set information to the Web Interface's classes.
  • The user then clicks on the application of interest to him/her to access it.

This test emulates a user accessing the XML service port and requesting for a list of applications available to him/her. By emulating a request, this test checks that the entire login and application enumeration process using the XML service and IMA service of Citrix is functioning properly.

Configurable parameters for the test
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 host listens to. By default, this is 80.

Connector URL

This test connects to the XML service through the Cloud Connector's URL. To enable this connection, specify the connector's URL here.


Specify the name of a user with access to one/more applications on the XenApp server.


Specify the password for the user specified above.

Confirm Password

Confirm the Password by retyping it here.


Enter the name of the domain to which the user specified above belongs.


Indicate the domain type.

No Of Tries and
Sleep Time

In environments where network connections are normally fuzzy and latencies are to be expected, the availability and response time checks performed by this test, may not always report accurate results. False alarms may hence be generated. In such environments therefore, you may want the test to try connecting to the XML service a few more times before reporting the availability and responsiveness of the service. To instruct the test to do so, you can use the No Of Tries and Sleep Time parameters. In the No Of Tries text box, indicate the number of times the test should try reconnecting to the XML service, and in the Sleep Time text box, specify how long (in seconds) the test should wait for a response from the service before attempting to reconnect. Both these parameters are set to 1 by default.


Specify the duration (in seconds) for which the test needs to wait for a response from the server. At the end of this duration, the test will timeout. The default is 30 seconds.

Encoding Format

By default, the Encoding Format is set to UTF-8, for providing code compatibility when the test is executed in different language platforms.

NFUSE Protocol Version

Specify the version of the NFUSE Protocol. By default the version is set to 5.1.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Connection availability

This metric tracks if the Citrix XML service is available to handle any requests.


If the TCP connection to the XML service port fails, this metric has a value of 0. Otherwise, it has a value of 100.

Authentication status

This metric indicates if the user authentication succeeded.


It has a value of 100 if the user was authenticated, and a value of 0 if the authentication failed. If the user login is valid, yet authentication fails, the problem then lies with the Citrix IMA service's communication with the domain controller/active directory server.

Application enumeration status

This metric indicates if the Citrix web interface was able to enumerate the applications available for the user logging in.


A value of 0 indicates that application enumeration failed, while a value of 100 denotes that the application enumeration operation succeeded. If authentication succeeds but application enumeration fails, then the problem is most likely to be in the Citrix XML service, its interaction with the IMA service, or with the IMA service itself.

TCP connection time

The time taken to establish a TCP connection to the Citrix XML service port


If this value is significantly high, it could probably be because the network latency is high or the Citrix web interface host is overloaded.

Total response time

This metric represents the total time taken for a user to login to the Citrix web interface and enumerate all the applications.


The value of this metric indicates the responsiveness of the Citrix web interface and its connectivity to the XML service.
