One of the key components of the Citrix access architecture is the Citrix Web Interface. When a user tries to login to the web front-end from a browser, the request is received and forwarded by the web interface to the XML broker. The XML service translates and then forwards the user's application list request to the Citrix IMA service. The IMA service uses the user information to contact the Domain controller to validate the user and his/her access rights. The IMA service then builds a list of applications that the user has access to and returns this list to the XML service, which in turn, reformats the output in XML format and returns it via the web interface to the user.
To periodically monitor the data-flow between the web interface, the XML service, and the IMA service, and to keep track of the web interface’s availability at all times, the eG Enterprise provides a specialized Citrix Web Interface monitoring model.
