This page provides an overview of the patches included in Dynatrace Operator version 1.6.1. For detailed information on new features and other enhancements, see the release notes for version 1.6.

Important notice

If you're running Dynatrace Operator version 1.6, we recommend upgrading to version 1.6.3 to receive the latest important patches.

Known Issues

We have identified the following known issues with Dynatrace Operator version 1.6.0 - 1.6.2.

In Kubernetes environments — especially those utilizing auto-scalers — there are challenges in reliably determining whether a node was intentionally removed or has failed unexpectedly. This ambiguity can lead to a high number of false-positive “Host is unavailable” alerts, impacting monitoring accuracy and alerting quality.

Resolved issues

The HostPath of the log monitoring DaemonSet was moved from /tmp/dynatrace to /var/opt/dynatrace to be consistent with the OneAgent.

Secrets generated by the new automatic-tls-certificate feature flag are now properly removed when the ActiveGate configuration is removed from a DynaKube.

Fixed a webhook panic error caused by a missing dynakube.internal.dynatrace.com/instance annotation in the referenced DynaKube.

The validation webhook now checks the .spec.ApiServer value in the EdgeConnect custom resource. Also the respective error message has been improved.

When autoUpdate was disabled and OneAgent version was set, updates by changing the version field were blocked. This issue has been resolved.

Removal and deprecation notices

The Helm repository located in dynatrace/helm-charts is deprecated and will stop receiving updates in a future release!
