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.

We plan to have ActiveGate version 1.325 as 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

Infrastructure Observability | Kubernetes

New self-monitoring metrics for ActiveGate Kubernetes monitoring

We have added the following self-monitoring metrics (dsfm) for ActiveGate Kubernetes monitoring:

  • active_gate.kubernetes.cache.eviction_count
  • active_gate.kubernetes.cache.size_available

Infrastructure Observability | ActiveGate

Updated ActiveGate installer to use JRE 17.0.15+6

To take advantage of performance improvements, the latest security-vulnerability enhancements, and bug fixes, we've upgraded JRE to JRE 17.0.15+6.

Infrastructure Observability | Azure

Migration from ADAL to MSAL

We have removed the dependency on the deprecated ADAL library and fully migrated to MSAL(Microsoft Authentication Library). This update improves security, aligning with Microsoft’s recommended authentication approach.

Platform

Upgrade of third-party Jetty WebServer functionality

The included Jetty WebServer functionality has been upgraded to version 10.0.25 in Dynatrace Server and ActiveGate.

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

Kubernetes | Inferred events

Inferred Kubernetes events

We have introduced a new event.provider for KUBERNETES_INFERRED_EVENT (for example, Workload spec change events).

For more information, see Inferred Kubernetes events.
