CloudWatch metrics that you can collect with CloudWatch RUM

The table in this section lists the metrics that you automatically collect with CloudWatch RUM. You can see these metrics in the CloudWatch console. For more information, see View available metrics.

You can also optionally send extended metrics to CloudWatch or CloudWatch Evidently. For more information, see Extended metrics.
