Citrix VDA Status - VM Test
Citrix Virtual Delivery Agent (VDA) is installed on a virtual machine that runs the applications or virtual desktops for the user. The VDA enables connections between the applications/desktops and the users only when the connections are brokered by Citrix. The VDA enables the virtual machines to register with Delivery Controllers and manage the High Definition experience (HDX) connection to a user device. If the VDA failed to register with a delivery controller, it would not be possible for the delivery controller to broker a connection to the target virtual machine. The target virtual machine would therefore become an unusable resource. The VDA issues with respect to registration are logged in the event log of the target virtual server. Some of the most common issues that are logged into the event log are the virtual desktop not added to the correct desktop farm, the virtual desktop firewall not configured properly, DNS configuration failure, Time synchronization failure, WCF failure etc. The eG agent integrates with the XDPing to collect the metrics that details on what exactly was the reason behind the registration issues i.e., what was the service that failed. The Citrix VDA Status - VM test helps administrators to figure out which service has failed leading to VDA registration issues!
This test monitors the VDA installed on the target virtual machine and reports whether the services such as user authentication, active directory authentication, DNS lookup, WCF endpoints etc are successful or not. This test also reports the errors and warnings available in the event log when registration failure occurs.
Note:
This test reports metrics only if the connections to the applications and desktops are brokered via Citrix XenDesktop 7.x.
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 the desired Component type, set 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 Hyper-V server
Agent deploying the test : A remote agent
Outputs of the test : One set of results for the virtual machine monitored.
