This publish is a part of an ongoing collection on governing the machine studying (ML) lifecycle at scale. To begin from the start, check with Governing the ML lifecycle at scale, Half 1: A framework for architecting ML workloads utilizing Amazon SageMaker.

A multi-account technique is crucial not just for enhancing governance but additionally for enhancing safety and management over the assets that assist your group’s enterprise. This strategy allows varied groups inside your group to experiment, innovate, and combine extra quickly whereas holding the manufacturing setting safe and accessible to your clients. Nevertheless, as a result of a number of groups would possibly use your ML platform within the cloud, monitoring massive ML workloads throughout a scaling multi-account setting presents challenges in organising and monitoring telemetry information that’s scattered throughout a number of accounts. On this publish, we dive into organising observability in a multi-account setting with Amazon SageMaker.

Amazon SageMaker Mannequin Monitor permits you to routinely monitor ML fashions in manufacturing, and alerts you when information and mannequin high quality points seem. SageMaker Mannequin Monitor emits per-feature metrics to Amazon CloudWatch, which you should use to arrange dashboards and alerts. You need to use cross-account observability in CloudWatch to go looking, analyze, and correlate cross-account telemetry information saved in CloudWatch reminiscent of metrics, logs, and traces from one centralized account. Now you can arrange a central observability AWS account and join your different accounts as sources. Then you possibly can search, audit, and analyze logs throughout your functions to drill down into operational points in a matter of seconds. You’ll be able to uncover and visualize operational and mannequin metrics from many accounts in a single place and create alarms that consider metrics belonging to different accounts.

AWS CloudTrail can be important for sustaining safety and compliance in your AWS setting by offering a complete log of all API calls and actions taken throughout your AWS account, enabling you to trace adjustments, monitor consumer actions, and detect suspicious conduct. This publish additionally dives into how one can centralize CloudTrail logging so that you’ve visibility into consumer actions inside your entire SageMaker environments.

Resolution overview

Clients usually wrestle with monitoring their ML workloads throughout a number of AWS accounts, as a result of every account manages its personal metrics, leading to information silos and restricted visibility. ML fashions throughout totally different accounts want real-time monitoring for efficiency and drift detection, with key metrics like accuracy, CPU utilization, and AUC scores tracked to take care of mannequin reliability.

To resolve this, we implement an answer that makes use of SageMaker Mannequin Monitor and CloudWatch cross-account observability. This strategy allows centralized monitoring and governance, permitting your ML crew to achieve complete insights into logs and efficiency metrics throughout all accounts. With this unified view, your crew can successfully monitor and handle their ML workloads, enhancing operational effectivity.

Implementing the answer consists of the next steps:

1. Deploy the mannequin and arrange SageMaker Mannequin Monitor.
2. Allow CloudWatch cross-account observability.
3. Consolidate metrics throughout supply accounts and construct unified dashboards.
4. Configure centralized logging to API calls throughout a number of accounts utilizing CloudTrail.

The next structure diagram showcases the centralized observability answer in a multi-account setup. We deploy ML fashions throughout two AWS environments, manufacturing and check, which function our supply accounts. We use SageMaker Mannequin Monitor to evaluate these fashions’ efficiency. Moreover, we improve centralized administration and oversight through the use of cross-account observability in CloudWatch to mixture metrics from the ML workloads in these supply accounts into the observability account.

Deploy the mannequin and arrange SageMaker Mannequin Monitor

We deploy an XGBoost classifier mannequin, educated on publicly accessible banking advertising and marketing information, to determine potential clients more likely to subscribe to time period deposits. This mannequin is deployed in each manufacturing and check supply accounts, the place its real-time efficiency is regularly validated in opposition to baseline metrics utilizing SageMaker Mannequin Monitor to detect deviations in mannequin efficiency. Moreover, we use CloudWatch to centralize and share the info and efficiency metrics of those ML workloads within the observability account, offering a complete view throughout totally different accounts. Yow will discover the complete supply code for this publish within the accompanying GitHub repo.

Step one is to deploy the mannequin to an SageMaker endpoint with information seize enabled:

endpoint_name = f"BankMarketingTarget-endpoint-{datetime.utcnow():%Y-%m-%d-%HpercentM}"
print("EndpointName =", endpoint_name)

data_capture_config = DataCaptureConfig(
enable_capture=True, sampling_percentage=100, destination_s3_uri=s3_capture_upload_path)

mannequin.deploy(
initial_instance_count=1,
instance_type="ml.m4.xlarge",
endpoint_name=endpoint_name,
data_capture_config=data_capture_config,)

For real-time mannequin efficiency analysis, it’s important to ascertain a baseline. This baseline is created by invoking the endpoint with validation information. We use SageMaker Mannequin Monitor to carry out baseline evaluation, compute efficiency metrics, and suggest high quality constraints for efficient real-time efficiency analysis.

Subsequent, we outline the mannequin high quality monitoring object and run the mannequin high quality monitoring baseline job. The mannequin monitor routinely generates baseline statistics and constraints primarily based on the offered validation information. The monitoring job evaluates the mannequin’s predictions in opposition to floor fact labels to verify the mannequin maintains its efficiency over time.

Banking_Quality_Monitor = ModelQualityMonitor(
    position=position,
    instance_count=1,
    instance_type="ml.m5.xlarge",
    volume_size_in_gb=20,
    max_runtime_in_seconds=1800,
    sagemaker_session=session,
)
job = Banking_Quality_Monitor.suggest_baseline(
    job_name=baseline_job_name,
    baseline_dataset=baseline_dataset_uri,
    dataset_format=DatasetFormat.csv(header=True),
    output_s3_uri=baseline_results_uri,
    problem_type="BinaryClassification",
    inference_attribute="prediction",
    probability_attribute="chance",
    ground_truth_attribute="label",
)
job.wait(logs=False)

Along with the generated baseline, SageMaker Mannequin Monitor requires two further inputs: predictions from the deployed mannequin endpoint and floor fact information offered by the model-consuming utility. As a result of information seize is enabled on the endpoint, we first generate site visitors to verify prediction information is captured. When itemizing the info seize recordsdata saved, you need to anticipate to see varied recordsdata from totally different time intervals, organized primarily based on the hour through which the invocation occurred. When viewing the contents of a single file, you’ll discover the next particulars. The inferenceId attribute is ready as a part of the invoke_endpoint name. When ingesting floor fact labels and merging them with predictions for efficiency metrics, SageMaker Mannequin Monitor makes use of inferenceId, which is included in captured information data. It’s used to merge these captured data with floor fact data, ensuring the inferenceId in each datasets matches. If inferenceId is absent, it makes use of the eventId from captured information to correlate with the bottom fact document.

{
"captureData": {
"endpointInput": {
"observedContentType": "textual content/csv",
"mode": "INPUT",

"encoding": "CSV"
},
"endpointOutput": {
"observedContentType": "textual content/csv; charset=utf-8",
"mode": "OUTPUT",
"information": "0.000508524535689503",
"encoding": "CSV"
}
},
"eventMetadata": {
"eventId": "527cfbb1-d945-4de8-8155-a570894493ca",
"inferenceId": "0",
"inferenceTime": "2024-08-18T20:25:54Z"
},
"eventVersion": "0"
}

SageMaker Mannequin Monitor ingests floor fact information collected periodically and merges it with prediction information to calculate efficiency metrics. This monitoring course of makes use of baseline constraints from the preliminary setup to constantly assess the mannequin’s efficiency. By enabling enable_cloudwatch_metrics=True, SageMaker Mannequin Monitor makes use of CloudWatch to watch the standard and efficiency of our ML fashions, thereby emitting these efficiency metrics to CloudWatch for complete monitoring.

from sagemaker.model_monitor import CronExpressionGenerator

response = Banking_Quality_Monitor.create_monitoring_schedule(
monitor_schedule_name=Banking_monitor_schedule_name,
endpoint_input=endpointInput,
output_s3_uri=baseline_results_uri,
problem_type="BinaryClassification",
ground_truth_input=ground_truth_upload_path,
constraints=baseline_job.suggested_constraints(),
schedule_cron_expression=CronExpressionGenerator.hourly(),
enable_cloudwatch_metrics=True,
)

Every time the mannequin high quality monitoring job runs, it begins with a merge job that mixes two datasets: the inference information captured on the endpoint and the bottom fact information offered by the appliance. That is adopted by a monitoring job that assesses the info for insights into mannequin efficiency utilizing the baseline setup.
