Datadog APM for GRPC and Databases

This example demonstrates adding Datadog tracing to GRPC clients, servers and database interactions. It contains:

• A simple protobuf definition for a "CRUD" service
• A GRPC client that interacts using the "CRUD" service
• A GRPC server that stores data in postgresql using standard database/sql methods
• A GRPC server that stores data in postgresql using gorm

Run using docker-compose

A simple way to build and run these applications is using docker-compose.

export DD_API_KEY="..." # enter your unique key here
docker-compose build
docker-compose up -d
docker-compose logs grpc-db-client

Example output

$ docker-compose logs grpc-db-client
Attaching to grpc-db_grpc-db-client_1

grpc-db-client_1     | 2019/09/09 18:04:46 queried. found = true name = foo

Run locally

These can be built and run locally:

go get github.com/DataDog/trace-examples/go/grpc/grpc-db/...

This will create the three applications:

• grpc-db-client
• grpc-dbsql-server
• grpc-gorm-server

To run these, a postgres database and datadog agent instance will be required.
