Understanding Audit Logs
Audit logs contain detailed information about various events happening in your Elasticsearch cluster. These logs are stored in the logs directory by default, and each log entry contains fields such as timestamp, node.name, event.action, user.name, and more.
Example Audit Log Entry
Here is an example of an audit log entry:
{
"timestamp": "2023-05-01T12:00:00Z",
"node.name": "node-1",
"event.type": "transport",
"event.action": "access_granted",
"user.name": "elastic",
"request.name": "BulkRequest",
"request.body": "{}"
}
This log entry indicates that a BulkRequest was made by the user elastic on node-1 at the specified timestamp.
