You can now monitor the availability of key processes on your hosts. For more information, see Process availability.
Process instance snapshots
The Process instance snapshots section of the new host overview page offers additional insights into the most resource-consuming processes running on your host and the processes defined for process availability monitoring. For more information, see Host monitoring with Dynatrace.
Added automatic detection of the WebSphere Liberty server name based on the Java command line. This detection rule must be activated only for existing environments:
Go to Settings > Processes and containers > Built-in detection rules.
Turn on Automatically detect WebSphere Liberty application.
z/OS
oneagentzos-R12370.pax is now available
PHP
Starting with this release, we support PHP code module on Linux ARM64 (AArch64).
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 your Java application with OpenTelemetry.
