Dynatrace Managed release notes version 1.214

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

Cluster Management Console

  • Open Identity Connect (SSO) can now use Internet proxy (aka Mission Control proxy) to reach Identity Provider authentication endpoints.

OIDC with proxy configuration

  • We introduced a request throttling mechanism to the Dynatrace API. For details, see Dynatrace API - Access limit.

  • Rack name selection was added to the new node installation wizard for a rack-aware deployment. It appears once you installed a node in another rack to ease further cluster scaling.

Installation and upgrade

  • To improve DNS load-balancing performance, web UI traffic is by default disabled when installing the 13th and subsequent nodes (or 7th and subsequent nodes in a data center for Premium HA). You can enable/disable web UI traffic for a node via the Cluster REST API.
  • For optimized performance and resilience, configuration and metric storage service was upgraded to Cassandra 3.11.10
  • Security enhanced by removing EXEC:ALL entry from dtrun sudoers setup
  • The JRE for Cassandra and Elasticsearch will now use version 8u282 to take advantage of performance improvements, the latest security-vulnerability enhancements and bug fixes. Other components remain using JRE 11.0.8
