Application Signals supported systems - Amazon CloudWatch
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Application Signals supported systems

Application Signals is supported and tested on Amazon EKS, native Kubernetes, Amazon ECS, and Amazon EC2. The instructions for enabling Application Signals on Amazon EC2 should work on any platform that supports the CloudWatch agent and Amazon Distro for OpenTelemetry, but the instructions have not been tested on other platforms.

Java compatibility

Application Signals supports Java applications, and supports the same Java libraries and frameworks as the Amazon Distro for OpenTelemetry does. For more information, see Supported libraries, frameworks, application servers, and JVMs.

JVM versions 8, 11, and 17 are supported.

Python compatibility

Application Signals supports the same libraries and frameworks as the Amazon Distro for OpenTelemetry does. For more information, see Supported packages at opentelemetry-python-contrib.

Python versions 3.8 and later are supported.

Before you enable Application Signals for your Python applications, be aware of the following considerations.

  • In some containerized applications, a missing PYTHONPATH environment variable can sometimes cause the application to fail to start. To resolve this, ensure that you set the PYTHONPATH environment variable to the location of your application’s working directory. This is due to a known issue with OpenTelemetry auto-instrumentation. For more information about this issue, see Python autoinstrumentation setting of PYTHONPATH is not compliant.

  • For Django applications, there are additional required configurations, which are outlined in the OpenTelemetry Python documentation.

    • Use the --noreload flag to prevent automatic reloading.

    • Set the DJANGO_SETTINGS_MODULE environment variable to the location of your Django application’s settings.py file. This ensures that OpenTelemetry can correctly access and integrate with your Django settings.
