How does a user start collecting a specific log for an Entity in Logging Analytics?

In OCI Logging Analytics, collecting logs for an Entity (a logical representation of a resource like a host or database) requires linking it to a Log Source.

Create an Association of required Log Source with that Entity (B): This is the correct step. An association connects an Entity (e.g., a server) to a Log Source (e.g., Syslog), specifying where and how logs are collected. Once associated, Logging Analytics begins ingestion and parsing.

Why not A, C, or D?

Configure a path (A): The path is part of the Log Source definition, not the act of starting collection.

Identify Fields (C): Field extraction is a post-collection step, not the initiation process.

Enable a Parser (D): Parsers are embedded in Log Sources; enabling them is implicit in the association, not a separate step.

This association is the foundational action to enable log collection.
