OpenSearch Service Serverless

Example CloudTrail Event #

This is a projected export row, not a complete CloudTrail record: it shows only the envelope columns a SIEM export retained. The export never carried userIdentity, requestParameters, responseElements, sourceIPAddress, recipientAccountId, eventCategory, so their absence here says nothing about the real event. Account identifiers, ARNs and endpoint hostnames in eventID, requestID, resources, tlsDetails, userAgent are replaced with the placeholders AWS uses in its own documentation, so those values are structurally real but not the originals. errorMessage is withheld: it is free-form prose that names customer resources, which no substitution rule can find reliably. eventTime is withheld because the export renders it in the exporting system's local timezone rather than the UTC a CloudTrail record carries.
