Announcements

End of support for private Synthetic locations on Amazon Linux 2

Chromium development for Amazon Linux 2 stopped at version 126. For important security and stability reasons, we've decided to discontinue our support for installing Synthetic-enabled ActiveGate on Amazon Linux 2 after ActiveGate version 1.307. We plan to have ActiveGate version 1.307 as the last Synthetic-enabled ActiveGate supported on Amazon Linux 2. Additionally, with Dynatrace version 1.308, we plan to introduce mechanisms preventing Synthetic-enabled ActiveGates on Amazon Linux 2 from being updated beyond version 1.307.

New features and enhancements

Feature update Dot Kubernetes

Additional dimensions on Prometheus metrics

Prometheus pod metrics now have the additional dimensions k8s.cluster.uid, k8s.workload.kind, and k8s.workload.name.

Feature update Dot Platform

Upgrade of Jetty to version 10

As part of this release, the included Jetty WebServer functionality is upgraded to version 10.0.24.

No manual user invention or downtime is necessary; the upgrade should happen via rolling updates as part of normal version updates.

In certain high-load scenarios, we have observed a slight increase in CPU and memory usage caused by implementation changes in Jetty 10. If ActiveGate instances are already at their resource limit, we recommend increasing them to avoid possible overload.
