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.
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
ModuleNotFoundErrorin 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.

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.

- If you’re able to install OneAgent, you should use OneAgent extensions.
- If you cannot install OneAgent (for example, if you need to monitor a remote technology), you should use ActiveGate extensions.
- If you simply want to monitor a Java application that exposes MBeans, use JMX/PMI extensions.
With OneAgent extensions, you can extend OneAgent monitoring to any OneAgent-detected processes that expose an interface (for example, processes that are served over HTTP—databases, applications, and load balancers). Extensions run within a OneAgent and fully integrate new-technology monitoring into Dynatrace Smartscape and problem detection. You need some Python expertise to develop OneAgent extensions. For more information, see OneAgent extensions.
With ActiveGate extensions, you can extend Dynatrace monitoring to any remote technology that exposes an interface, where OneAgent installation isn't an option. For example, PaaS technologies, network devices, or cloud technologies. ActiveGate extensions (aka Remote Plugins) are executed on ActiveGate and can acquire metrics and topology from remote sources, fully integrating new-technology monitoring into Dynatrace Smartscape and problem detection. You need some Python expertise to develop ActiveGate extensions. For more information, see Introduction to ActiveGate extensions.
The Extension SDK is a versatile solution that enables you to monitor any custom technology that exposes an interface. Develop and deploy your extensions. Dynatrace can seamlessly integrate your custom-technology monitoring data into relevant analysis views, taking full advantage of all your favorite Dynatrace features and AI-driven root cause analysis.
