Dynatrace Managed release notes version 1.228
These release notes relate to Dynatrace Managed specific changes. To learn about general Dynatrace changes included in this Dynatrace Managed release, see:
New features and enhancements
General
- Removed deprecated endpoints
/metrics/seriesand/metrics/descriptorsin favor of/metrics/queryand/metrics. - You can now pin a filtered Problems dashboard tile from the Problems page.
User action naming rules are automatically migrated to enhanced user action naming where possible.
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.
- 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.
On the service details page, we have improved how the initial analysis timeframe is selected to make sure it always contains data.
- We have introduced a new
KEYS(customProperty)function for our User Sessions Query Language (USQL). Use this function to get keys of user action and user session properties according to the property data type defined in the argument. See Custom queries, segmentation, and aggregation of session data for details. We have added an in-product feature for users to share feedback about Davis in problem analysis views. Providing feedback helps us review how Davis is performing and make improvements where possible.
To improve web application monitoring, you can now configure "Angular package name" for Angular 12 applications.
OpenSSL library, used by Nginx service, was updated to version 1.1.1l for increased resilience and security
Metric and configuration storage database was updated to Cassandra 3.11.11 for improved resilience
We now set Dynatrace Managed deployment components metadata via environment variables to leverage Dynatrace Release inventory capability. You can see this in your self-monitoring environment. The following variables are set:
DT_RELEASE_VERSION for Version
DT_RELEASE_STAGE for Stage
DT_RELEASE_PRODUCT for Product
