1gRPC Observability Example 2===================== 3 4The examples here demonstrate how to setup gRPC Python Observability with Opentelemetry. 5 6More details about how to use gRPC Python Observability APIs can be found in [OpenTelemetry Metrics gRFC](https://github.com/grpc/proposal/blob/master/A66-otel-stats.md#opentelemetry-metrics). 7 8### Install Requirements 9 101.
