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

1. Navigate to this directory:

cd examples/python/observability

2. 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.

grpc.server.call.duration

Client Side:

Greeter client received: Hello You
Metrics exported on client side:
