# Audit logs

> Set up audit logging in Omni to track user activity with structured event logs delivered to Amazon S3, Google Cloud Storage, or Azure Blob Storage.

Audit logs are detailed records of the activity your users are taking in Omni, which can be useful for security and performance analysis. Events included in logs are structured as JSON payloads and sent in batches to cloud storage a few minutes after they're written.

## Delivery destinations

Audit logs can be delivered to Amazon S3, Google Cloud Storage, or Azure Blob Storage.

## Data retention

By default, logs are retained for at least one year. Contact Omni support if you need a shorter retention period.

## Event types

Each audit log entry includes an event type that identifies the user action that triggered it. See the [event types reference](/administration/audit-logs/event-types) for a full list of supported events and their payload fields.
