Data Collection Schedule

The module application.yml and its profile-specific variants are authoritative for attribute codes, types, default values, scheduling, health, and local buffering. Keep this README aligned when that metadata changes.

Configured in application-dev.yml:

dc3:
  driver:
    schedule:
      read:
        cron: '0/1 * * * * ?'   # Every second

Running Locally

1. Start Infrastructure and Center Services

make up-db
make up-dev GROUP=core

2. Build and Run

mvn -s .mvn/settings.xml -pl dc3-driver/dc3-driver-virtual -am package
java -jar dc3-driver/dc3-driver-virtual/target/dc3-driver-virtual.jar

3. Verify Registration

The driver logs show gRPC registration with Manager Center on startup:

Driver register success, service name: dc3-driver-virtual

Testing

Run the module tests from the repository root:

mvn -s .mvn/settings.xml -pl dc3-driver/dc3-driver-virtual -am test
