Measures reported by CtxXmlAccessTest

The CtxXmlAccessTest 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 executes on a Citrix Web Interface, and can be optionally enabled to execute on a Citrix XenApp server. 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 the XML service and IMA service of Citrix is functioning properly.

Measurement Description Measurement Unit Interpretation
Connection_availability This metric tracks if the Citrix XML service is available to handle any requests. Percent 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 Percent 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.
App_enumeration_status This metric indicates if the Citrix web interface was able to enumerate the applications available for the user logging in. Percent 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 Secs 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. Secs The value of this metric indicates the responsiveness of the Citrix web interface and its connectivity to the XML service.
