Audit events are a subset of the MAAS event logs. This article will provide reference material for those who want to review and report on events designated as MAAS audit events.
MAAS audit events can be viewed via the CLI with a command similar to the following:
maas $PROFILE events query level=AUDIT
Such a command would produce JSON output like this:
Machine-readable output follows:
