Store browser screenshots on your cluster

Starting with version 1.216, for fresh-installed Dynatrace Managed, the private Synthetic browser monitor screenshots are stored on the Cluster, and not uploaded to the S3 bucket. Contact Dynatrace ONE if you wish to enable Cluster-side screenshot storage on pre-1.216 fresh-installed Clusters.

General

  • If you opt out of automatic update downloads, you'll receive email notifications with download URLs when new update packages are available. See Update Dynatrace Managed topic.
  • License-related in-product notifications should now be visible only to cluster administrators.
  • Since Dynatrace Managed 1.216, user behavior information is part of Dynatrace deployment health monitoring. Dynatrace no longer sends user data to 3rd party companies.

42 total resolved issues

ActiveGate

Cluster

  • During a fresh installation, directories `/opt/dynatrace` and `/opt/dtrun` can no longer be specified for Dynatrace Managed binaries or data. (APM-289525)
  • Resolved issue to prevent UI crash when results contain no data. We have added a check to verify that the internal data to create the response is correct. (APM-291799)
  • Resolved issue that caused Smartscape topology to sometimes truncate result counts. (APM-288329)
  • "Contains" string operations now honor the case sensitivity flag for calculated service metric conditions. (APM-300406)
