Audit and Access Logs

This section covers Alluxio's two log types that record activity inside the cluster. Together they provide the data you need for security auditing, compliance, and operational insight into cache behavior.

Both log types share the same dynamic configuration surface — see Dynamic Configuration via REST API and CLI for how to enable, disable, and tune them at runtime.

Audit Log

A structured, JSON-formatted record of operations performed within the system, used to monitor sensitive data access, track administrative commands, and meet regulatory requirements. Covers management operations through the Gateway and data access through the S3, HDFS, FUSE, and Python SDK interfaces.

Access Log

A deduplicated record of key cache-lifecycle operations on Workers — LOAD, HOT_READ, COLD_READ, EVICT, and DELETE — designed to support data governance and cache observability under high concurrency without flooding log storage.
