Monitor Amazon SageMaker with Amazon CloudWatch

You can monitor Amazon SageMaker using Amazon CloudWatch, which collects raw data and processes it into readable, near real-time metrics. These statistics are kept for 15 months, so that you can access historical information and gain a better perspective on how your web application or service is performing. However, the Amazon CloudWatch console limits the search to metrics that were updated in the last 2 weeks. This limitation ensures that the most current jobs are shown in your namespace. To graph metrics without using a search, specify its exact name in the source view. You can also set alarms that watch for certain thresholds, and send notifications or take actions when those thresholds are met. For more information, see the Amazon CloudWatch User Guide.

SageMaker Endpoint Invocation Metrics

The AWS/SageMaker namespace includes the following request metrics from calls to InvokeEndpoint.

Metrics are available at a 1-minute frequency.

For information about how long CloudWatch metrics are retained for, see GetMetricStatistics in the Amazon CloudWatch API Reference.

Endpoint Invocation Metrics

Metric	Description
Invocation4XXErrors	The number of InvokeEndpoint requests where the model returned a 4xx HTTP response code. For each 4xx response, 1 is sent; otherwise, 0 is sent. Units: None Valid statistics: Average, Sum
Invocation5XXErrors	The number of InvokeEndpoint requests where the model returned a 5xx HTTP response code. For each 5xx response, 1 is sent; otherwise, 0 is sent. Units: None Valid statistics: Average, Sum
Invocations	The number of InvokeEndpoint requests sent to a model endpoint. To get the total number of requests sent to a model endpoint, use the Sum statistic. Units: None Valid statistics: Sum
InvocationsPerInstance	The number of invocations sent to a model, normalized by InstanceCount in each ProductionVariant. 1/numberOfInstances is sent as the value on each request, where numberOfInstances is the number of active instances for the ProductionVariant behind the endpoint at the time of the request. Units: None Valid statistics: Sum
ModelLatency	The interval of time taken by a model to respond as viewed from SageMaker. This interval includes the local communication times taken to send the request and to fetch the response from the container of a model and the time taken to complete the inference in the container. Units: Microseconds Valid statistics: Average, Sum, Min, Max, Sample Count
OverheadLatency	The interval of time added to the time taken to respond to a client request by SageMaker overheads. This interval is measured from the time SageMaker receives the request until it returns a response to the client, minus the ModelLatency. Overhead latency can vary depending on multiple factors, including request and response payload sizes, request frequency, and authentication/authorization of the request. Units: Microseconds Valid statistics: Average, Sum, Min, Max, Sample Count

Multi-Model Endpoint Model Instance Metrics

Metric

Description

LoadedModelCount

The number of models loaded in the containers of the multi-model endpoint. This metric is emitted per instance. The Average statistic with a period of 1 minute tells you the average number of models loaded per instance. The Sum statistic tells you the total number of models loaded across all instances in the endpoint. The models that this metric tracks are not necessarily unique because a model might be loaded in multiple containers at the endpoint. Units: None Valid statistics: Average, Sum, Min, Max, Sample Count

SageMaker Jobs and Endpoint Metrics

The /aws/sagemaker/ProcessingJobs, /aws/sagemaker/TrainingJobs, /aws/sagemaker/TransformJobs, and /aws/sagemaker/Endpoints namespaces include the following metrics for the training jobs and endpoint instances.

Metrics are available at a 1-minute frequency.

Note

Amazon CloudWatch supports high-resolution custom metrics and its finest resolution is 1 second. However, the finer the resolution, the shorter the lifespan of the CloudWatch metrics. For the 1-second frequency resolution, the CloudWatch metrics are available for 3 hours. For more information about the resolution and the lifespan of the CloudWatch metrics, see GetMetricStatistics in the Amazon CloudWatch API Reference.

Tip

If you want to profile your training job with a finer resolution down to 100-millisecond (0.1 second) granularity and store the training metrics indefinitely in Amazon S3 for custom analysis at any time, consider using Amazon SageMaker Debugger. SageMaker Debugger provides built-in rules to automatically detect common training issues; it detects hardware resource utilization issues (such as CPU, GPU, and I/O bottlenecks) and non-converging model issues (such as overfit, vanishing gradients, and exploding tensors). SageMaker Debugger also provides visualizations through Studio and its profiling report. To explore the Debugger visualizations, see SageMaker Debugger Insights Dashboard Walkthrough, Debugger Profiling Report Walkthrough, and Analyze Data Using the SMDebug Client Library.
