Dynatrace extension framework upgrade notice

Starting with Dynatrace OneAgent and ActiveGate version 1.231, we are upgrading the Extension Framework (also referred to as the plugins framework) from Python 3.6 to Python 3.8.

  • Consequences: Some Dynatrace extensions running in your environment may stop working and require redeployment of a new version prepared for Python 3.8.
  • Symptoms:
    • No data is provided for affected metrics on dashboards, alerts, and custom device pages populated by the affected extension metrics.
    • Extension logs display errors. Most often this will manifest itself as Python ModuleNotFoundError in the PluginAgent log.
    • Sometimes the Python virtual machine crashes.
  • Impact: This issue affects only those extensions that use native libraries called from Python code distributed with the extension.

Extension

What to do

  1. In Dynatrace Hub, find and select one of the extensions listed to the left.
  2. On the extension details page, select Download to download the extension ZIP file to your machine. If there are operating system options, be sure to select the correct download for your deployment.
  3. Deploy the extension per the instructions on the corresponding documentation page. (In the list to the left, select the name of the extension.)

For assistance, contact a Dynatrace product expert via live chat within your Dynatrace environment.

No action required. Extensions distributed with OneAgent will be updated automatically to work with Python 3.8 together with the Python upgrade.

To learn about upgrading custom Dynatrace extensions from Python 3.6 to Python 3.8, see Upgrade custom Dynatrace extensions from Python 3.6 to Python 3.8.

Chromium support update

Chromium 97 was originally the latest supported version for Synthetic-enabled ActiveGate version 1.235 for Ubuntu 18.04 and 20.04, Red Hat Enterprise Linux and CentOS 8, and bundled with the Windows installer. However, because of a number of vulnerabilities discovered in Chromium 97, starting with Synthetic module version 1.235.43.20220310-144212, we've changed the latest supported version to Chromium 99, which is the latest version that fixes these issues.

You will get Chromium 99 automatically for these Linux-based operating systems if you've selected Enable Chromium Auto-update for your private locations. Otherwise, you need to update Chromium manually—see Manage private Synthetic locations. Chromium is always updated automatically on Windows-based ActiveGates.

Previously, Chromium development for Red Hat Enterprise Linux/CentOS 7 had stopped at version 90. Chromium 99 is now available for Red Hat Enterprise Linux/CentOS 7 with ActiveGate version 1.235.

  • Starting with Chromium 98, TLS 1.0 and 1.1 are not supported.
  • Chromium development for Ubuntu 16.04 stopped at version 90.
