InfluxDB Configuration

1. Open InfluxDB Admin interface: http://db-server:8086
2. Click “Get Started”
3. Setup initial configuration:
   • Username and Password for access to Admin interface
   • Organization name
   • Bucket name - by the default is astra but you may define any bucket name in the Astra settings
4. Click “Quick Start”
5. In the Admin interface create Token for Astra: Data -> Tokens -> Generate -> Read/Write Token
6. Set token description and choose “astra” or “All Buckets” for Read and Write permission and click “Save”
7. Click on the new token and copy it to the clipboard

Done. InfluxDB configured and ready to receive data.

Astra Configuration

1. Open Astra Admin interface: http://astra-server:8000
2. Open Settings -> General
   • “Instance Name” - by the default is astra will be used as bucket in the InfluxDB
   • “InfluxDB Address” - address of the InfluxDB: http://db-server:8086
   • “InfluxDB Organization” - your orgranization in the InfluxDB settings
   • “InfluxDB Token” - paste your token from clipboard
3. Click “Apply & Restart”
