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 model training jobs and endpoints write CloudWatch metrics and logs. The following tables list the metrics and dimensions for SageMaker.

Multi-Model Endpoint Model Instance Metrics
The /aws/sagemaker/Endpoints namespaces include the following instance 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.
| 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 |

Processing Job, Training Job, Batch Transform Job, and Endpoint Instance 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.
| Metric | Description |
|---|---|
CPUUtilization |
The percentage of CPU units that are used by the containers on an instance. The
value can range between 0 and 100, and is multiplied by the number of CPUs. For example,
if
there are four CPUs, For training jobs, the value is the CPU utilization of the algorithm container on the instance. For batch transform jobs, the value is the CPU utilization of the transform container on the instance. For endpoint variants, the value is the sum of the CPU utilization of the primary and supplementary containers on the instance. For multi-instance, each instance reports CPU utilization metrics. However, the default view in CloudWatch shows the average CPU utilization across all instances. Units: Percent |
MemoryUtilization |
