New features and enhancements

Log Monitoring

Integrate OpenTelemetry Node.js on Azure Functions consumption plan

Azure Functions offer multiple hosting options with different ways to integrate distributed tracing. You can now configure tracing Node.js services running on Azure Functions under the default Consumption Plan, with a dedicated Dynatrace package for OpenTelemetry. For details, see Trace Azure Functions written in Node.js.

Group IMS regions belonging to the same subsystem into a process group

Added ability to group IMS regions that belong to the same subsystem into a single process group. For more information, see Transaction monitoring.
