Send Fluent Bit logs to Axiom

Fluent Bit

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.


Visit the Fluent Bit download page to install Fluent Bit on your system.

You'd need to specify the org-id header if you are using Personal Token, it's best to use an API Token to avoid the need to specify the org-id header.

Fluent Bit configuration file supports four types of sections:

  • Service: Defines global properties of your service using different keys available for a specific version.
  • Input: Defines the input plugin and base configuration of your file.
  • Filter: Defines the input plugin and configure the pattern tags for your configuration.
  • Output: Specify a destination that certain records should follow after a Tag match.

All sections will be configured in your .conf file.
