Send data from Fluent Bit to Axiom

Fluent Bit is an open-source log processor and forwarder that allows you to collect any data like metrics and logs from different sources, enrich them with filters, and send them to multiple destinations like Axiom.

​

Prerequisites

• Create an Axiom account.
• Create a dataset in Axiom where you send your data.
• Create an API token in Axiom with permissions to update the dataset you have created.

• Install Fluent Bit.

​

Configure Fluent Bit

1. Set up the Fluent Bit configuration file based on the Fluent Bit documentation.

2. In the Fluent Bit configuration file, use the HTTP output plugin with the following configuration. For more information on the plugin, see the Fluent Bit documentation.

   • Replace AXIOM_URL with api.axiom.co if your organization uses the US region, and with api.eu.axiom.co if your organization uses the EU region. For more information, see Regions.
   • Replace API_TOKEN with the Axiom API token you have generated. For added security, store the API token in an environment variable.
   • Replace DATASET_NAME with the name of the Axiom dataset where you want to send data.
