Dynatrace Managed version 1.276 introduces a range of updates and enhancements, including support for Red Hat Enterprise Linux 8.x and 9.x clusters, the transition of the Thresholds API functionality to metric events via the Settings API, and the requirement for a minimum ActiveGate version 1.263 to access the latest Kubernetes features. The release also includes new downloadable z/OS modules for mainframe monitoring, expanded operating system support for private Synthetic locations, and improved host settings descriptions. Consistency in alerting profile filters and notification engines across the web UI and REST API has been improved, along with cluster backup validation procedures. Several issues have been resolved, such as improved ActiveGate update reliability, correct linking in Kubernetes event cards, and refined Davis root cause analysis algorithms. Additionally, the update addresses memory usage in metrics queries, UI glitches, and issues with chat features and remote deletions in Multi-DC environments. Future operating system support changes are outlined, with certain Linux versions losing support by December 2025 and January 2026.
