CloudWatch metrics for Amazon VPC Lattice

Amazon VPC Lattice sends data related to your target groups and services to Amazon CloudWatch, and processes it into readable, near real-time metrics. These metrics 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. 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.

Amazon VPC Lattice uses a service-linked role in your AWS account to send metrics to Amazon CloudWatch. For more information, see Using service-linked roles for Amazon VPC Lattice.

  2. In the navigation pane, choose Metrics.

  3. Select the AWS/VpcLattice namespace.

  4. (Optional) To view a metric across all dimensions, enter its name in the search field.

  5. (Optional) To filter by dimension, select one of the following:

    • To display only the metrics reported for your target groups, choose Target groups. To view the metrics for a single target group, enter its name in the search field.

    • To display only the metrics reported for your services, choose Services. To view the metrics for a single service, enter its name in the search field.

To view metrics using the AWS CLI
