Dynatrace OneAgent Automatic update failures

[awahab]

If Dynatrace Oneagent Automatic update fails in Windows, it will keep retrying the download filling up the drive.

The root cause for the failure may be several , but because of the infinite downloads, the drive get filled up and causing outage.

Did anyone face this issue? Found any solution or workaround. 

P.S : Support was not able to resolve the issue.

Hello @awahab 

Really interesting. I would also like to hear more about this.

Sample screenshot below. What you see is the E:\AI_RecycleBin(ignore the naming used 😀) filled with the Dynatrace binaries since the auto-update is failing.

IMO - we just experienced this and crazy that it was causing space issues.  it was using 64GB of space.  

Dynatrace, might want to review this.

We also see one of the application team come up with the same concern. I am also eager to know the solution.

We continue to see this is issue when we attempt to update the oneagent. It may be one or two hosts, but sometimes it can be multiple.

Our analysis shows that the oneagent update will fail due to the previous msi file missing and so the uninstall cannot proceed. This is still a mystery to why the msi file is missing and not sure if instructions are sent from the oneagent update to clean up the old msi even though the update fails. 

Once the update fails, the AI_RecylcleBin will eventually fill up causing the drive to run out of space. It requires manual intervention to:

• Delete the AI_RecycleBin to reclaim the space
• Download the previous oneagent version to the host. Sometimes this requires reaching out to support to make the version available to us for download
• Extract the msi and place it in the %WINDIR%\Installer directory with the name referenced in the uninstall error
• Run the uninstall 
• Reinstall the oneagent to the newer version

It is understandable that the update may fail sometimes but having the AI_RecycleBin fill up and create an outage is unacceptable.

We just had this happen on 3 of our servers too. The folder size grew enormous and consumed the majority of the available disk space on the drives. 

I checked and all 3 servers had the same error for the OneAgent automatic updates.

This thread has been open for a long time, so for reference, here's the version we're on, and the version it was trying to update to:

Hi @awahab 

You can check the below references:

• https://docs.dynatrace.com/docs/shortlink/oneagentctl#automatic-updates
• https://docs.dynatrace.com/docs/shortlink/oneagentctl#check-if-auto-update-is-enabled
• https://docs.dynatrace.com/docs/shortlink/oneagentctl#enable-or-disable-auto-update

Depending on the OS, you can enable or disable the auto-Update through "dynatrace.conf" file.

Tip:

• Stop the Oneagent service > Apply the required change > Restart Oneagent service again.

To set a specific OA version it's achievable through the UI.

Alternatively:

• Proceed with the most stable version through the UI.
• Ensure the allocated resources are exceeding the suggested specs by Dynatrace https://docs.dynatrace.com/docs/ingest-from/dynatrace-oneagent/installation-and-operation/windows/in...

Hoping it helps.

Hi @awahab 

If none of the appreciated workarounds works for the raised concern:

• Proceed with the complete Uninstallation, followed by directories removal.
• Restart the target server.
• Conduct a fresh deployment.
