Citrix Server VDA Status Test
The Virtual Delivery Agent (VDA) enables connections to applications and desktops. The VDA is installed on the Citrix Virtual Apps server that runs the applications or virtual desktops for the user. It enables the 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 Citrix Virtual Apps server. The target Citrix Virtual Apps server would therefore become an unusable resource. The VDA issues with respect to registration are logged in the event log of the target Citrix Virtual Apps 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 Server VDA Status test helps administrators to figure out which service has failed leading to VDA registration issues!
This test monitors the Virtual Delivery Agent installed on the target Citrix Virtual Apps server 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.
Target of the test : Any Citrix server
Agent deploying the test : An internal/remote agent
Outputs of the test : One set of results for the Citrix Virtual Apps server monitored
| Parameters | Description |
|---|---|
|
Test Period |
How often should the test be executed. By default, this is 15 minutes. |
|
Host |
The host for which the test is to be configured. |
|
Port |
Refers to the port used by the Citrix server . |
|
DD Frequency |
Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 6:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency. |
|
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:
