Graylog's Archiving and Audit Log Features
Graylog Enterprise, built on top of the Graylog open source platform, offers additional features that enable users to deploy Graylog at enterprise scale and apply Graylog to processes and workflows across the whole organization.
The Audit Log feature is valuable for compliance purposes and keeps track of changes made by users to a Graylog system. Archiving is useful in controlling the cost of storage by archiving log messages until you need to re-import for analysis.
