InfluxDB is an open-source time series database.

InfluxDB Configuration

Open the InfluxDB Admin interface at http://db-server:8086.

First, create a new bucket. A bucket serves as storage for all data received from Astra. You can find buckets in the left sidebar under the “Load Data” group. To create a new bucket:

1. Click Create Bucket
2. Set the bucket name, for example, astra
3. Set data retention: in the Delete Data section, select Older than and choose 30 days or any other value you prefer.

The next step is to grant Astra access to the bucket. In the left sidebar under the Load Data group, open API Tokens:

1. Click Generate API Token and choose Custom API Token.
2. Set the token description as astra
3. In the Bucket group, set Read and Write permissions for the astra bucket.
4. Click Generate

Now, InfluxDB is configured and ready to receive data.

Astra Configuration

Open Settings → General in the Astra Web Interface. Set options for InfluxDB configuration:

• 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 generated on previous step
• Click “Apply & Restart”
