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 13th and following node (or 7th and following in a datacenter for Premium HA). You can enable/disable Web UI traffic for a node via 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

Cluster REST API

Delivered product ideas

RFE: Add a configuration of proxy for the SSO – SAML or OpenId in Dynatrace GUI
