GitHub Copilot · Via Relay Server

Deploy an internal relay server that forwards telemetry to Milestone.

Server Setup (Linux)​

Step 1: Download & extract the OTEL client​

Download otel-client-claude-code.tar.gz, then extract:

tar -xvzf otel-client-claude-code.tar.gz
cd otel-client-claude-code

Step 2: Configure the .env file​

Copy .env.example to .env and set:

OTEL_SERVER_ENDPOINT=https://telemetry.mstone.ai
OTEL_SHARED_SECRET=<your-shared-secret>

Step 3: Start the relay​

docker compose up -d

The relay listens on port 4318 (OTLP/HTTP). Ensure it is reachable from developer machines.
