docker compose up -d mqtt tdengine

Configure EMQX

• Visit emqx dashboard at localhost:18083
• Login with user name admin and password public
• Create data bridge in Integration
  • URL: http://tdengine:6041/influxdb/v1/write?db=traffics

  • Body: velocity,device_id=${payload.device_id} speed=${payload.speed}
• Create rules in Integration
  • SQL Editor:

Run Virtual MQTT Device

docker compose up -d virtdev

Run GCRNN and Grafana

docker compose up -d grafana gcrnn

Check Grafana Dashboard

Visit localhost:3000, login as user admin with password admin123. Then find default dashboard Velocity in General folder.

Run demo with telegraf and eclipse-mosquitto

We can use eclipse-mosquitto and telegraf instead of EMQX in this demo.

docker compose down
docker compose -f docker-compose-telegraf.yml pull
docker compose -f docker-compose-telegraf.yml up -d

After all containers are brought up successfully, visit localhost:3000 to visit the dashboard.
