    G -- "Visualize (HTTP)" --> I

1. Create external network.

   docker network create external
   

   TODO: This network setting is for test in local environment.

2. Move to monitor directory.

3. Create myInfluxDBVolume and myGrafanaVolume directory.

4. Create .env file.

   DOCKER_INFLUXDB_INIT_USERNAME=<InfluxDB admin user name>
   DOCKER_INFLUXDB_INIT_PASSWORD=<InfluxDB admin password>
   DOCKER_INFLUXDB_INIT_ORG=<InfluxDB initial organization>
   DOCKER_INFLUXDB_INIT_BUCKET=<InfluxDB initial bucket>
   GF_SECURITY_ADMIN_PASSWORD=<Grafana admin password>
   

5. Run docker compose --env-file=../.env up -d.

6. Open localhost:8086 (InfluxDB) via browser.

7. Generate API Token for the bucket.

8. Open localhost:8080 (Grafana) via browser.

9. Setup InfluxDB integration.

   • Query languabe
     • Flux
   • HTTP
     • URL: http://influxdb:8086
   • Auth
     • (None)
   • InfluxDB Details
     • Set the information

10. Move to "sensor" directory.

11. Set environment variables.

    $ENV:INFLUXDB_BASE_URL = "http://localhost:8086"
    $ENV:INFLUXDB_TOKEN = "<InfluxDB user token>"
    $ENV:INFLUXDB_ORG = "<InfluxDB organization>"
    $ENV:INFLUXDB_BUCKET = "<InfluxDB bucket>"
    

12. Run npx tsc ./src

13. Run node ./dist/main.js

14. Open localhost:8080 (Grafana) via browser.

15. Check the data.
