Data Store Check Test

When a XenApp server farm is deployed, it must have an associated data store. The data store provides a repository of persistent information, including:

  • Farm configuration information
  • Published application configurations
  • Server configurations
  • Citrix administrator accounts
  • Printer configurations

When servers in a zone attempt to come online, they query the data store for configuration information via the ZDC.  If the data store is unavailable or is inaccessible to the ZDC for long hours, servers in the zone will remain offline the whole time, thus denying users access to their critical applications. To avoid this, administrators can run the Data Store Check test at frequent intervals, check whether/not the ZDC is able to connect to the data store, and in this way, detect connection failures before farm users complain. In the event of a connection failure, administrators can also use the detailed metrics collected by this test to determine the reason for the connection failure and resolve it.

Target of the test : Any Citrix ZDC

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the Citrix ZDC monitored

Configurable parameters for the test
Parameters Description

Test Period

This indicates how often should the test be executed.


The host for which the test is to be configured.


Refers to the port used by the Citrix ZDC.


This test uses Virtual Apps' Data Store Checker tool to verify whether/not the monitored ZDC is able to connect to the data store. To enable the test to use this tool, you need to specify the full path to the location of DSCheck.exe in the DscheckPath text box. For instance, your path can be: C:\Program Files (x86)\Citrix\system32.

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:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Connectivity status

Indicates whether the ZDC succeeded or failed in establishing a connection with the data store.


The values that this measure can take and their corresponding numeric values are as follows:

Measure Value Numeric Value
Failure 0
Success 1

If the value reported is Failure, you can use the detailed diagnosis of this test to determine the reason for the connection failure.


By default, this measure reports the above-mentioned Measure Values to indicate the connectivity status of the data store. However, the graph of this measure will represent the same using the numeric equivalents only.
