Python solarwinds-apm

An OpenTelemetry Python distribution for SolarWinds Observability. Provides automatic configuration, instrumentation, and APM data export for Python applications.

Requirements

All published artifacts support Python 3.10 or higher. A full list of system requirements is available at SolarWinds Observability System Requirements.

See CONTRIBUTING.md for how to build for development.

Getting Started

SolarWinds APM captures OpenTelemetry distributed traces and metrics from your application and sends them to SolarWinds Observability for analysis and visualization.

To install solarwinds-apm and all relevant Opentelemetry Python instrumentation libraries:

pip install solarwinds-apm "psutil>=5.0"
opentelemetry-bootstrap --action=install

solarwinds-apm already includes OpenTelemetry and therefore doesn't need to be installed separately. Python agent installation should be done after installation of all other service dependencies. This is so opentelemetry-bootstrap detects those packages and installs their corresponding instrumentation libraries. For example:

pip install -r requirements.txt           # installs all other dependencies
pip install solarwinds-apm "psutil>=5.0"
opentelemetry-bootstrap --action=install

Set the service key and ingestion endpoint. An easy way to do this is via environment variables available to your application process. An example:

export SW_APM_SERVICE_KEY=<set-service-key-here>
export SW_APM_COLLECTOR=<set-collector-here>

Run your application with the prefix opentelemetry-instrument to wrap all common Python frameworks and start exporting OpenTelemetry traces and metrics:

opentelemetry-instrument <command_to_run_your_service>

You can also add custom span generation to your code by using the OpenTelemetry SDK. For example:

from opentelemetry import trace
tracer = trace.get_tracer(__name__)

with tracer.start_as_current_span("my_custom_span") as custom_span:
   custom_span.set_attribute("my_custom_attribute", "foo_value")
   print("Here is my custom OpenTelemetry span")

Documentation

OpenTelemetry Python documentation is available at the OpenTelemetry-Python API Reference.

Online documentation for SolarWinds APM Python features, configuration, and more is available at SolarWinds Observability.

Contributing

OpenTelemetry Python would not be possible without collaborations and efforts from many contributors. Our common goals as a community are to improve end user/developer experiences and empower them.
