New features and enhancements
PHP Wordpress OneAgent feature
You can now enable the PHP Wordpress OneAgent feature that extends the distributed traces with the Wordpress instance specific context. After you enable the feature, the distributed tracess will report the Wordpress instance name (php.wordpress.blog.name) and the Wordpress framework entry point processing the request.
Learn how to enable OneAgent features.
New IMS message processing region process ID calculation
z/OS
The IMS message processing region (MPR) process IDs could change, resulting in new process and service entities in Dynatrace. To prevent this process ID change, we’ve introduced a more stable ID calculation with the consequence that all IMS MPR process and service entities will change once but then remain stable after an update of the zRemote module with OneAgent version 1.253.
To opt out of the new IMS MPR process ID calculation, see Customize the zRemote module.
Container monitoring - cgroups v2 support
Infrastructure Monitoring | Containers
Since OneAgent version 243, OneAgent has supported containers based on Control Group v2 (cgroup v2), but this required that OneAgent be deployed on the host or in Kubernetes as a privileged OneAgent container or in a non-Kubernetes Docker container with cgroupns=host parameter. For details, see Introducing cgroups v2 support.
Starting with OneAgent version 1.253, support for containers based on cgroup v2 has been extended to cases in which OneAgent is deployed in a Kubernetes unprivileged container or in a non-Kubernetes Docker container without the cgroupns=host parameter.
AWS Nitro hypervisor is now detected
Infrastructure Monitoring | Hypervisors
The AWS Nitro hypervisor type is now detected on Windows and Linux.
Tracing SQS-triggered AWS Lambda for Python & Node.js (manual)
Apps & Microservices | Distributed Traces
The Dynatrace AWS Lambda extension for Python and Node.js now supports tracing for AWS SQS. For details, see OpenTelemetry interoperability.
