Query related to "The Data Collector Set or one of its dependencies is already in use."

Question

Background:

When our application is trying to collect the Windows host performance stats using Perfmon tool; we observed that the performance stats are not getting collected. We are seeing the following error when perfmon tool is trying to collect the Windows host data.

Error:

The Data Collector Set or one of its dependencies is already in use.

I am suspecting that this exception might be the reason of data gaps in Windows hosts' performance reports. Can anyone please confirm if this understanding is correct or not.

I would like to know in which case does this error occurs? And what's the impact of this error on data collection.

Also, how to troubleshoot the problem when this exception occurs and if there is any solution to this.

Answer 1

The error code 0x803000AA typically indicates that the Data Collector Set or one of its dependencies is already in use. This can occur when attempting to start a performance log or system diagnostic that conflicts with an existing process or service using the same resources.

Troubleshooting steps to follow include the following:

Ensure that no other performance logs or diagnostics are currently running that may conflict with the Data Collector Set you are trying to start.

Check the Event Viewer for any related errors that might provide more details on the conflict.

Use the DISM (Deployment Image Servicing and Management) tool to repair system files, which can be done by executing the command DISM.exe /Online /Cleanup-Image /RestoreHealth in an elevated PowerShell or Command Prompt.

In some cases, booting the computer in Safe Mode and then running the SFC scan can help resolve issues that can't be fixed in the normal operating mode.

If the above steps do not resolve the issue, you might need to consider using the Reset PC feature to reset your system, which can help fix problems caused by corrupted system files or configurations.
