Announcements

End of support for private Synthetic locations on Red Hat/Oracle Linux/Rocky Linux 8

There are no new versions of Chromium for Red Hat/Oracle Linux/Rocky Linux 8 beyond version 133. For important security and stability reasons, we've decided to discontinue our support for installing Synthetic-enabled ActiveGate on Red Hat/Oracle Linux/Rocky Linux 8 after ActiveGate version 1.325.

To ensure the continuity and security of your synthetic monitors, we recommend migrating your Synthetic-enabled ActiveGate to one of the supported operating systems, for example Red Hat/Oracle Linux/Rocky Linux 9.

ActiveGate version 1.325 is the last Synthetic-enabled ActiveGate supported on Red Hat/Oracle Linux/Rocky Linux 8.

Additionally, with Dynatrace version 1.326, we plan to introduce mechanisms preventing Synthetic-enabled ActiveGates on Red Hat/Oracle Linux/Rocky Linux 8 from being updated beyond version 1.325.

New features and enhancements

Platform

Upgrade of third-party Jetty WebServer functionality to version 12

As part of this release, the included Jetty WebServer functionality is upgraded to version 12.0.22 in the Dynatrace Cluster and ActiveGate.

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

Note: In certain high-load scenarios, we experienced a slight increase in CPU and memory usage caused by implementation changes in Jetty 12. If ActiveGate instances are very short on resources, we advise a slight increase to avoid potential overload.

Infrastructure Observability | Kubernetes

Inferred Kubernetes events are now also available as an event metric

The Kubernetes event count metric dt.kubernetes.events (builtin:kubernetes.events in the previous Dynatrace) now also includes inferred Kubernetes events OOMKilled and Workload spec change.
