How long are versions supported following rollout?

ActiveGate installer on Linux requires multi-user.target

The ActiveGate installer on Linux requires the Linux boot process to be finished, which means that multi-user.target has to be active on your system. Otherwise, the installation is aborted.

The ActiveGate installer starts the dynatracegateway service during the installation process to download ActiveGate modules and the service depends on multi-user.target.

ActiveGate base image set to UBI Micro

To increase the security, we set the ActiveGate base image to Red Hat's UBI Micro.

Java update

To take advantage of performance improvements, the latest security-vulnerability enhancements, and bug fixes, we've updated the ActiveGate installer to use Java Runtime Environment (JRE) version 11.0.16.1.

Ubuntu 16 for private Synthetic locations end of support

As Chromium development for Ubuntu 16.04 stopped at version 90, we can no longer assure a high enough level of stability and security for synthetic monitor execution on Ubuntu 16. We have discontinued our support for installing Synthetic-enabled ActiveGate on Ubuntu 16 after ActiveGate version 1.251. That is, ActiveGate version 1.251 is the last Synthetic-enabled ActiveGate supported on Ubuntu 16.

With Dynatrace version 1.254, Synthetic-enabled ActiveGates on Ubuntu 16 can no longer be updated.

Chromium support for private Synthetic locations

Chromium 105 is the latest supported version for Synthetic-enabled ActiveGate installed on:

  • Ubuntu 18.04, 20.04, and 22.04
  • Red Hat Enterprise Linux 7 and 8
  • CentOS 7
  • Amazon Linux 2

Chromium 105 is bundled with the Windows ActiveGate installer.

For more information on supported and provided Chromium versions, see Requirements for private Synthetic locations and Create a private Synthetic location.
