Node.js handlers bundled via esbuild to CommonJS can now be auto-instrumented by OneAgent. However, as in the following example command, the packages must be external to be instrumented via OneAgent. Example command:
New workaround flag to remove synchronized calls on z/OS and AWS Lambda to improve virtual thread support
Java 21 introduced the highly anticipated virtual threads functionality with one major caveat: virtual threads pinned the host thread on synchronized calls. This was resolved with Java 25. However, when using Java 21-24 under heavy load and leveraging virtual threads, you can potentially encounter a deadlock. This was the situation in the Lambda/zOS agent, which has a few synchronized blocks that led to deadlocks. To resolve this, we now provide a workaround flag enable-modern-locking=true, which replaces all synchronized calls with newer Java locking APIs.

Breaking changes
Infrastructure Observability
Escape characters only for Metrics
You can use escape characters only in Metrics. The use of escape characters ensures consistent enrichment between metrics and events, providing more reliable data and easier analysis.
Fixes and maintenance
General Availability (1.329.66.20260109-142000)
Optimized memory usage: fixed a memory leak in the ADO SQL v2 Sensor that happened when both tracing and Flawfinder sensors are active, ensuring smoother application performance. (OA-57259)
Enhanced log compatibility: added full support for JSON format in logs for containerized applications, simplifying log analysis (OA-57124)
OneAgent Log Module and the Log Module no longer mark false-positive text content in container logs as binary content. (OA-57063)
Improved resource efficiency: resolved excessive resource usage in zRemote caused by faulty data from the IMS code module, ensuring stable operations. (OA-57053)
Fixed directory pattern normalization for Windows OS. Previously, it was not possible to configure and provide logs from the main disk directory. This issue is now resolved. (OA-56777)
Accurate disk alerting: fixed an issue that triggered disk alerts for unavailable disks, improving alert reliability. (OA-56693)
Unicode support: dimension values containing Unicode characters are now accurately reported, ensuring precise data representation. (OA-56689)
Correct Kafka queue reporting: fixed an issue in the OneAgent Python code module, where the kafka-python consumer sensor reported an incorrect queue vendor string, preventing duplicate queue entities in Dynatrace Classic. (OA-56636)
Reliable host metrics: fixed the host.name dimension for the dt.host.availability metric to account for all hostname sources, ensuring accurate monitoring. (OA-56625)
Accurate LPAR reporting: Linux LPARs now correctly report their virtualization type, improving infrastructure visibility. (OA-56137)
Streamlined Python tracing: fixed the OpenTelemetry feature in the Python code module to correctly apply span settings rules, reducing unnecessary traces and improving monitoring efficiency. (OA-55972)
Consistent metric collection: fixed an issue where system time changes caused metric loss in the OneAgent network module, ensuring uninterrupted data collection. (OA-55882)
Improved live debugger conditions: added support for comparing null and undefined string values. (OA-55819)
Improved span relationships: resolved an edge case in the Python OpenTelemetry module to ensure proper parent-child span relationships, enhancing trace accuracy. (OA-55588)
Faster application initialization: addressed an issue where Runtime Application Protection and Runtime Vulnerability Analytics caused temporary memory spikes and slower startup times, improving initialization performance. (OA-55433)
Accurate host identification: fixed an issue where the host ID was calculated using an incorrect IP address, ensuring proper LPAR registration. (OA-55275)
Reliable HTTP responses: resolved a rare bug where IIS altered 1-byte HTTP response payloads, ensuring accurate response delivery. (OA-54895)
Increased ARM64 stability: fixed a crash when static applications receive Linux signals during Go module execution. (OA-54490)
Better trace propagation: resolved threading sensor issues to ensure proper handling of ignored and sampling states. (OA-53672)
The --get-app-log-content-access oneagentctl option was fixed by migrating OneAgent configuration files during installation to the proper format and location, and using the migrated configuration file to set the value provided by that option. (OA-52705)

Changed the user action detection in RUM to be in sync with RUM Classic user action detection. (DEM-19884)
Improved the time to capture the page dimensions on page loads (DEM-17042)
The zDC wasn’t fully connecting to the zRemote. The zRemote now handles this scenario and entirely disconnects from the zDC. This forces the zDC to attempt a brand new connection, which should succeed. (OA-58570)
Fixed an issue where log reports from containerized applications, which were logged in the local time zone without a time zone indication in the timestamp format, were ingested with an incorrect timestamp value. (OA-58490)
