Question:

Is it possible to monitor the Direct Audit Collector(s) outside of Audit Manager to determine if it is connected or disconnected?


Answer:

Yes, one way that could be used to monitor the Collector status is to use the 'Get-CdaCollector' cmdlet from the Audit Modules for Powershell.

The Audit Modules for PowerShell will need to be installed first. 
 
Please see the below documentation on how the Audit Modules for PowerShell can be installed, if it isn't already.
https://docs.centrify.com/Content/aud-ps/PowerShellAuditModuleInstall.htm

After the Audit Modules are installed, open up a PowerShell prompt with Administrative rights by right clicking on the PowerShell Application icon and choosing Run As Administrator.

The Get-CdaCollector cmdlet can then be used to find information about your collector(s).  The Status field in the output will show connection status.
 
See the example below:
 


To filter only on the Status field the command could be run as follows.
