gRPC Observability Example
The examples here demonstrate how to setup gRPC Python Observability with Opentelemetry.
More details about how to use gRPC Python Observability APIs can be found in OpenTelemetry Metrics gRFC.
Install Requirements
- Navigate to this directory:
cd examples/python/observability
- Install requirements:
python -m pip install -r requirements.txt
Run the Server
Start the server:
python -m observability_greeter_server
Run the Client
Note that client should start within 10 seconds of the server becoming active.
python -m observability_greeter_client
Verifying Metrics
The example will print a list of metric names collected.
