The Chronicle output plugin allows ingesting security logs into Google Chronicle service. This connector is designed to send unstructured security logs.
Fluent Bit streams data into an existing Google Chronicle tenant using a service account that you specify. Therefore, before using the Chronicle output plugin, you must create a service account, create a Google Chronicle tenant, authorize the service account to write to the tenant, and provide the service account credentials to Fluent Bit.
To stream security logs into Google Chronicle, the first step is to create a Google Cloud service account for Fluent Bit:
Fluent Bit does not create a tenant of Google Chronicle for your security logs, so you must create this ahead of time.
Fluent Bit's Chronicle output plugin uses a JSON credentials file for authentication credentials. Download the credentials file by following these instructions:
See Google's official documentation for further details.
