This page showcases new features, changes, and bug fixes in Dynatrace OneAgent version 1.333. It contains:
Application Observability | Log Analytics
Monitor state and health of Log modules using self-monitoring events
We introduced a new functionality to monitor and troubleshoot Log modules.
It includes a pre-made dashboard that contains two main functionalities:
- A list of all detected log sources with their current monitoring status.
- A list of all detected and potential issues in the environment, with links to relevant documentation.
The functionality requires Log Management and Analytics powered by Grail, with support for OneAgent and Dynatrace Operator deployment modes. It is disabled by default and can be manually activated via the Settings API.
Oldest supported versions
With this release, the following are the oldest supported OneAgent versions.
For details, see How long are versions supported following rollout?.
Feature updates
Application Observability | Distributed Tracing
New automatic instrumentation for AWS Lambda in Go
We added new AWS Lambda layers for automatic Go instrumentation (tracing, log correlation). The new support includes the generic AWS SDK and SNS.
Application Observability | Distributed Tracing
Support for Spring Boot 4.0 and Spring Framework 7.0
OneAgent now supports Spring Boot 4.0 and Spring Framework 7.0 versions.
Application Observability | Distributed Tracing
Automatic span suppression for OpenTelemetry in Node.js code module
We have introduced automatic suppression of OpenTelemetry spans based on the OpenTelemetry instrumentation library name. If a OneAgent sensor is available that instruments the same library as the OpenTelemetry instrumentation, OpenTelemetry spans are automatically suppressed to avoid double tracing. For a list of OpenTelemetry instrumentation libraries affected by this behavior, see Prevention of span duplication in Node.js.
Application Observability | Log Analytics
Added detection of a plain IIS configuration
We've introduced the Detection of a plain IIS configuration feature that enables OneAgent to assign logs to the appropriate IIS application pools unambiguously.
When the feature is activated, OneAgent verifies whether the IIS setup is complex or plain. A plain configuration means that a single application pool is assigned to a single site, and there is no central log shared across the entire IIS instance.
The plain configuration assigns logs to the processes of individual pools instead of assigning all logs to a single IIS process.
To activate the Detection of a plain IIS configuration feature:
Digital Experience | RUM Web
RUM JavaScript Classic allows you to resume automatic page detection
You can now call to restore automatic page detection after using manual page detection.
Infrastructure Observability | Azure
We have added a new integration option to monitor Azure App Service on Linux using the sidecar pattern. This provides a simplified integration with code-only and custom container deployments.
Platform
Added support for Fedora 43
We have added support for Fedora 43.
Platform | OneAgent
Support for Redisson Tracing
Tracing support for Redisson is now available, including support for tracing queries and batched queries. To enable this, turn on Java Redisson Redis client. This instrumentation can optionally distinguish between batch operations (turned off by default).
Platform | OneAgent
Support for ES6 modules in Node.js
ES6 modules are now supported in Node.js.
Platform | OneAgent
Support for Vert.x HttpClient and Vert.x WebClient
Tracing support is now available for WebClient and HttpClient for versions 3.6+, 4.X, and 5.X.
Platform | OneAgent
Added Python 3.14 distribution for extensions
We have added the Python 3.14 distribution to the OneAgent deployment for extensions.
Breaking changes
Infrastructure Observability | Extensions
Run your extensions with Python runtime version 3.14
Python extensions can now be run with Python 3.14. To enable this, rebuild the extension with the newest Python SDK.
Fixes and maintenance
General Availability (1.333.36.20260304-162231)
- Fixed an issue that resulted in incorrectly high alert numbers in certain Process metrics (IO Read/Writes per second, IO Requested Reads/Writes per second, page faults per second). (OA-62263)
- The Single Middleware Injection feature now works for .NET 7 and later. In rare cases, this feature is needed to work with certain authenticators. (OA-61437)
- Fixed an issue that occasionally triggered availability alerts for non-existing PGIs. (OA-61378)
- Fixed case sensitivity when searching for or attributes in JSON documents. (OA-60996)
- Fixed attribute sourcing from SMBIOS System Information ( and ) for OneAgent on Linux, ensuring accurate and consistent system metadata reporting. Previously, it used chassis metadata for and , leading to inaccurate system identification. (OA-60568)
- Fixed an issue with log inline enrichment not allowing slashes in the attribute names. (OA-60504)
- Fixed Go Business Events to take the content length limit into account when capturing plain-text HTTP response bodies. (OA-60131)
- Fixed the failure issue in Live Debugger auto source fetching caused by the environment variables. (OA-60121)
- The comparison of executable names and paths is now case sensitive. It now allows matching executables with different casing on Linux systems. (OA-60035)
- Back and front slashes are now supported for the Process Availability exe path matcher on Windows. (OA-59805)
- Fixed retrieval of IIB/ACE message flow node names when node names exceeded 256 characters, which previously resulted in incorrect values. (OA-59765)
- The Cloud Detection task now has more time to complete and collect attributes from REST endpoints with the implementation of lazy initialization for the immutable list of resource attributes. Previously, Cloud resource attributes (for example, and ) were missing on spans. (OA-59686)
- Fixed zRemote parsing issue when configured for log ingestion. (OA-59582)
- Fixed the indefinite growth of the Cassandra PGI name when deployed in Kubernetes pods in certain scenarios. (OA-59467)
- We now support detection and tracing for methods with or/and annotations for versions 2.5+. (OA-59449)
- Updated metrics sent from OneAgent to the December 2025 specification update. That update relaxed the requirements for the first character of the dimensions key from to the regex . Characters previously converted to will now remain unchanged. (OA-59395)
- Postgres child processes are no longer grouped under the Postgres parent when it's grouped declaratively. (OA-59147)
- Fixed the issue with the custom configuration of BizEvents sensor. (OA-59134)
- Fixed HTTP request timeouts in Apache Server monitored by OneAgent when a 100-Continue response was expected and the request body was captured as a Business event. (OA-58446)
- Vulnerability: Fixed a vulnerability for OneAgent and ActiveGate Windows installers that could lead to privilege escalation in certain situations. (OA-58439)
- Enabled functionality to improve resource attribute enrichment in . (OA-57123)
- Fixed possible stack overflow during Go code module crash handling in Go >= 1.21. (OA-56021)
- Added support for handling user-specific settings in RemotePluginModule. (DAQ-21395)
- Fixed an issue in SNMP extensions where metrics were reported even when their filtered dimension data was not collected. Metrics are now emitted only when all filtered dimensions are present and meet their defined filter criteria. For details on SNMP filter behavior, see SNMP data source reference. (DAQ-19103)
