Dynatrace SaaS release notes version 1.227

Web application monitoring

To improve web application monitoring, you can now configure Angular package name for Angular 12 applications.

Application Security

  • New metrics related to process groups are now available.
  • You can now define custom security-monitoring rules based on host tags and management zones in your Kubernetes environment. You need to add tags on the host and on the Kubernetes node.

Dashboards

You can now pin a filtered Problems dashboard tile from the Problems page.

Kubernetes

The Kubernetes cluster details page now has additional navigation controls that make it possible to navigate to the related namespaces, workloads, and pods of the Kubernetes cluster. Also, to improve consistency with other Kubernetes pages, navigation links on the Kubernetes cluster details page have been moved to the browse menu () in the upper-right corner of the page.

ingress-nginx instrumentation for Kubernetes

You can manually instrument the NGINX process of the official ingress-nginx controller container image on Kubernetes by editing the configmap. See Instrument ingress-nginx for Kubernetes for details.

Dynatrace API

To learn about changes to the Dynatrace API in this release, see Dynatrace API changelog version 1.227.

Heads up: endpoints to be removed

Deprecated API v2 endpoints /metrics/descriptors and /metrics/series will be removed as of Dynatrace SaaS version 1.228.

These endpoints are superseded by endpoints /metrics and /metrics/query respectively. To learn how to use these endpoints, see Metrics API - GET metrics and Metrics API - GET metric data points.
