Feature updates

All | Metrics Ingestion Protocol

OpenTelemetry/OTLP metrics ingest: All resource attributes now available in Metrics powered by Grail

All attributes present on the OTLP resource are now ingested as dimensions in Metrics powered by Grail.

The following settings for OTLP metrics ingest are available to tailor the behavior to your needs:

  • A deny list to drop unwanted attributes of any source—OTLP data point, scope, or resource—that is applied to both Metrics powered by Grail and Metrics Classic.
  • An allow list to select which attributes should be ingested as dimensions on Metrics Classic, with no impact on Metrics powered by Grail.

These changes continue to strengthen security and cost tracking with fine-grained access control and cost breakdowns (for example, using dt.cost.costcenter) and prepare your metrics for chargebacks and security monitoring while keeping data management efficient.

To enable this new version of the OTLP metrics ingest, in Dynatrace Classic, go to Settings > Metrics > OpenTelemetry metrics, and turn on Advanced OTLP metric dimensions.

For further details about these changes and their effect on enrichment with the dt.entity.service dimension, see OTLP Metric Dimensions Changes in the Dynatrace Community.

Infrastructure Observability

Kubernetes enhanced object visibility: Additional container fields

ActiveGate Kubernetes monitoring now writes additional fields for the CONTAINER Smartscape node (if available via Kubernetes API):

  • container.id
  • container.image.name
  • container.image.version

Infrastructure Observability

Improved outbound performance of ActiveGate

We improved the outbound performance of ActiveGate by better managing the HTTP connections—we reduced the number of SSL handshakes by re-using HTTP connections more frequently.

Infrastructure Observability | AWS

Updated AWS SDK for Java to version 2

This ActiveGate release includes an update to the AWS monitoring module, which now utilizes the AWS SDK for Java v2.33.5. To ensure continued security, performance, and access to critical updates, we recommend updating all environments running the AWS monitoring module. As SDK V2 only supports STS regional endpoints in order for AWS monitoring to work, make sure you have enabled STS endpoints for the regions you want to monitor.

If your Dynatrace environment has automatic updates enabled, no manual action is required—the update will occur via rolling updates.

If updates are managed manually, follow the instructions in Update ActiveGate to update to ActiveGate version 1.331.

Software Delivery

Automatic update retry for ActiveGate on Linux

ActiveGate on Linux now automatically retries failed updates. If the installation of a newer version of ActiveGate or a module fails, the autoupdater tries again without re‑downloading the installer after 12 hours (initial try and 3 retries).

Software Delivery

Added File Access Policy management

We introduced File Access Policy (fapolicyd) management for the ActiveGate installation process. The installer automatically manages ActiveGate rules in the correct order to grant the necessary permissions for the Dynatrace user and group. For more details on File Access Policy management, see Chapter 12. Blocking and allowing applications by using fapolicyd in the Red Hat documentation.

    Fixes and maintenance

    Resolved issues in this release

    • Fixed an issue where the self-monitoring metric presenting information about rejected messages (dsfm:active_gate.communication.messages.rejected) was missing part of the rejections related to an unavailable environment when OneAgent was using legacy basic authorization. (DAQ-17842)
