Feature Request Audit Logs

Public Preview

This feature is currently in Public Preview.

This feature has the following limitations:

• Must be enabled by Tecton Support.

If you have questions or want to share feedback, please file a support ticket.

Feature Request Audit Logs allow you to see what requests are being sent to your production feature serving endpoint.

Use Cases for Feature Request Audit Logs

• Prevent data leakage. You can integrate audit logs with SIEM (like Splunk) and detect malicious activity (abnormal number of requests/login brute force).
• Reports for audit. You can download all logs within a time frame and, for example, ensure that old api keys were rotated and no longer used.

How to Use

• Contact Tecton Support to enable the feature.
• Once the feature is enabled, You will be able to find logs written to your Cloud Provider's Object Storage (e.g. s3://tecton-{DEPLOYMENT_NAME}/logging/audit_logs/) where your logs will be partitioned by time and written as new line separated json objects.

Possible values for Result field in requestDetails include: MissingMetadata, MissingAuthorization, CouldNotDecodeApiKey, InvalidApiKey, or an empty string for successful auth.

Write Frequency

In order to optimize the response latency of feature serving requests, request audit logs are batched and written asynchronously. By default, they will be written either every 60 seconds or if buffer size reaches 1024 bytes, unless customized as per customer request. This behavior means if the cloud provider experiences an outage, up to 60 seconds of logs could fail to be persisted.
