Audit Event Index


Account Type Account Level
Cloud Flex Trial, Enterprise
Credits Trial, Enterprise Operations, Enterprise Security, Enterprise Suite

The Audit Event Index provides event logs in JSON on activities from your account allowing you to monitor and audit changes. Enterprise accounts have the Audit Event Index enabled and available to search by default. You can use the Enterprise Audit Apps to visually display data from the Audit Event Index for monitoring and analysis.

This index is improved and different from the Audit Index, and there is some overlap of audited events. The Audit Index provides event logs in plain text and audits when account limits are reached and operation failures, like throttling and scheduled search events.


All available audited events are documented for your reference. This documentation is hosted on each deployment, instead of on this document. Sumo Logic has several deployments that are assigned depending on the geographic location and the date an account is created. See how to determine which endpoint to use if you are unsure.

Search the Audit Event Index

Searching the Audit Event Index is the same as running a normal search against your ingested data. You specify the _index metadata field with one of these values: 

  • sumologic_audit_events. This index contains user action events, which are events that were triggered by a user action, either from the UI or an API.
  • sumologic_system_events. This index contains system action events, which are events that were triggered by Sumo Logic, for example throttling events, rules triggered, and so on.  

For example, to search for user action events:

  1. In the Search page, enter the following:
  2. Choose the time range for the incidents that you'd like to review.
  3. Click Start to run the search.

Audited events

This index has detailed JSON logs for the following features. To search audit events for a specific feature use the metadata field _sourceCategory with its corresponding value. For example, to search events for access keys you would use the query:

_index=sumologic_audit_events _sourceCategory=accessKeys

Index retention period

By default, the retention period of the Audit Event index is the same as the retention period of your Default Continuous Partition. You can change the retention period by editing the relevant partitions, sumologic_audit_events and sumologic_system_events. For more information, see Edit a Partition.
