Bug Fixes

A range of high-impact bugs have been resolved in this release. Be sure to review the full list included below for more details.

Category Updated Summary Issue Key
Core

Veeam 13 Automatic Service Discovery

Summary: N-central now detects and automatically onboards Veeam Backup & Replication 13 installations.

Issue: Previously, devices running Veeam 13 were not recognized by the service template discovery process, preventing Veeam monitoring services from being deployed automatically. Partners had to manually configure monitoring after installing Veeam 13.

Fix: The N-central Agent has been updated to recognize Veeam 13 and automatically deploy the appropriate Veeam monitoring service templates, restoring the expected onboarding experience.

Updated Built-in Veeam Monitoring Services for Veeam 13

Summary: Updated the following built-in Veeam monitoring services to support Veeam Backup & Replication 13:

  • Veeam Failed Jobs 

  • Veeam Job Monitor 

  • Veeam Sure Job Monitor 

Issue: Veeam 13 requires PowerShell 7 (pwsh) for its PowerShell modules. The existing monitoring services used Windows PowerShell, preventing them from collecting monitoring data correctly in Veeam 13 environments.

Fix: The Automation Manager policies have been updated to execute using PowerShell 7, ensuring the built-in monitoring services function correctly with Veeam 13 while remaining compatible with earlier supported Veeam versions.

Automation Manager

AMP Monitoring: Resolved Invalid Script Format Errors

Summary: Resolved an issue that could cause custom Automation Manager Policy (AMP) monitoring services to report a 201: Invalid Script Format error, even when the underlying scripts were valid.

Issue: In certain environments, an invalid Automation Manager token registry state could cause AMP to incorrectly interpret valid monitoring scripts as invalid, resulting in monitoring failures across affected devices.

Fix: This update corrects the Automation Manager token registry handling to prevent invalid registry states from impacting script execution. AMP monitoring services now process valid scripts correctly, eliminating these erroneous validation failures.

AM-6515
Patch Management

Patch Management: Immediate Pre-download Maintenance Windows No Longer Become Stuck

Summary: Resolved an issue where immediate pre-download maintenance windows could become permanently stuck in the queue when there were no approved patches available to download.

Issue: Previously, if a pre-download maintenance window found no approved patches, the schedule could fail to complete correctly, preventing subsequent maintenance windows from running until manual intervention.

Fix: This update ensures immediate pre-download maintenance windows complete successfully even when there is nothing to download, allowing queued maintenance windows to continue processing as expected. Patch-on-Boot maintenance windows are unaffected by this change.
