PHP

Starting with this release, we support PHP code module on Linux ARM64 (AArch64).

IBM Integration Bus

New features and enhancements

OneAgent OS module

Host CPU is now measured properly when there are multiple processor groups on a Windows host.

OpenTelemetry Java agent auto-instrumentation

Dynatrace is now compatible with the OpenTelemetry Java auto-instrumentation agent. This means that the OpenTelemetry Java agent can now be used to gain insights out of Java frameworks not supported by OneAgent, such as Elasticsearch clients, Couchbase, and Apache Camel. For more information, see Automatically instrument Java applications with OpenTelemetry.
