Monitoring with Model Monitor, CloudWatch, and CloudTrail

Prepare baselines and capture policies

• Derive baseline statistics from recent production windows and store them with constraints that reflect contractual SLAs.
• Version capture schemas so future pipeline changes still land in comparable folders for Model Monitor to consume.
• Load the mock payloads in assets/datasets/monitoring to rehearse baseline uploads and capture replays locally.

Automate Model Monitor schedules

• Create hourly quality schedules per endpoint, referencing the correct statistics and constraints URIs.
• Run monitors under a dedicated role that can write metrics, logs, and new reports without exposing production secrets.
• Persist outputs to a lifecycle-managed bucket so long-term trends remain queryable but storage stays under control.

Route insights to operators and auditors

• Wire CloudWatch alarms to SNS topics feeding paging channels, email digests, and ticket queues.
• Mirror drift summaries into your incident knowledge base so root causes and remediation steps stay discoverable.
• Enable CloudTrail across regions to capture who muted alarms, changed schedules, or modified baselines.

Explain the observability stack via CloudFormation

Deploy monitoring-observability-stack.yaml and use the highlighted snippets to connect infrastructure components to the operational story.

• Resources:
    BaselineBucket:
      Type: AWS::S3::Bucket

  Acts as the single source of truth for baselines, captures, and monitor outputs with versioning and lifecycle policies.

• Resources:
    MonitoringRole:
      Type: AWS::IAM::Role

  Shows the scoped execution role that emits metrics and writes reports without broad account permissions.

• Resources:
    MonitoringSchedule:
      Type: AWS::SageMaker::MonitoringSchedule

  Demonstrates the hourly data-quality job definition teams can duplicate per endpoint.

• Resources:
    DriftAlarm:
      Type: AWS::CloudWatch::Alarm

  Highlights how constraint violations become actionable alerts piped into SNS.

• Resources:
    Trail:
      Type: AWS::CloudTrail::Trail

  Captures who adjusted monitoring or alarms so compliance teams trust the evidence trail.
