Why it matters
Useful records can connect an action with an account, time, resource, and outcome. They help investigate events such as permission changes, unusual exports, or an unexpected alteration to a sample record.
A practical example
Imagine a profile becomes searchable after its settings change. An audit trail may show when the change occurred and which account or process made it, helping distinguish several possible explanations.
An important distinction
A log entry is evidence, not an infallible account. Missing events, shared accounts, inconsistent clocks, or altered logs can limit its meaning. Logging itself also creates records that need appropriate access and retention decisions.
