Dynatrace Managed release notes version 1.290
Rollout start: Apr 29, 2024
Announcements
Direct acquisition of AWS logs via AWS Data Firehose
Infrastructure Observability | Log Monitoring
Amazon Data Firehose integration (available in preview from Dynatrace Managed version 1.288) is now in General Availability. Firehose integration allows ingest of cloud logs directly, without additional infrastructure needed, and at higher throughput. It replaces the deprecated AWS log forwarder. Full production support starts from cluster version 1.288.
Breaking changes
Additional failure detection rules for Unified services
Application Observability | Distributed traces
We improved unified service failure detection rules for requests on endpoints and incoming services mesh proxies to evaluate
Span status failure
Server-side errors with HTTP status code 500-599
Any exception
New features and enhancements
Third-party default monitoring mode
Application Security | Vulnerabilities
Third-party Vulnerability Analytics has a configurable monitoring mode.
In Settings > Application Security > General settings > Third-party Vulnerability Analytics, you can now define the default monitoring mode for all processes, thus reducing complexity when defining monitoring rules.
For details, see Configure the global third-party vulnerability detection control.
Enrichment of cloud application topology using semantic dictionary attributes
Infrastructure Observability | Kubernetes
The process of enriching topology for cloud applications effectively utilizes specified semantic dictionary attributes, including:
k8s.workload.kind
k8s.workload.name
Span kind endpoint detection
Application Observability | Services
Endpoint detection rules for unified services evaluate spans at the beginning of the trace.
Improved concurrent autoupdate handling
Infrastructure Observability | Hosts Infrastructure Observability | Deployment
The default limit for concurrent OneAgent autoupdates has been increased to 5, so the overall speed of the update process will increase. Higher limits will of course not be reduced. Also, potential problem handling has been changed to be more tolerant.
.NET support for RVA and RAP
Application Security | Vulnerabilities
.NET technology is now available for Runtime Vulnerability Analytics (code-level vulnerability detection) and Runtime Application Protection (attack protection).
-
To enable RVA monitoring for .NET code-level vulnerabilities
-
To enable RAP monitoring for attacks in .NET technology
With this release, preview customers for .NET technology (RVA and RAP) need to upgrade to OneAgent version 1.289 to reactivate this functionality. After that, no further configuration is necessary.
Switching to cloud-native full-stack deployment as default
Infrastructure Observability | Kubernetes
With the release of Dynatrace Operator version 1.0.0, the deployment page for Kubernetes Classic has been updated to default to cloud-native full-stack instead of the classic full-stack. Additionally, we have shifted to using Helm by default instead of manifests.
All previously available deployment options, including the manifest-based approach, remain accessible through our documentation. For more details on the differences between these deployment options, see How it works.

- The `faultyVersion` property of the code module provided as a response for the "OneAgent on a host API" now takes into account two reasons a code module could be considered faulty: (1) the code module itself is marked as faulty or (2) the installer is marked as faulty. (DMX-7196)
Update 53 (Build 1.290.53)
This cumulative update contains 5 resolved issues and all previously released updates for the 1.290 release.
