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.

View Amazon CloudWatch metrics

You can view the Amazon CloudWatch metrics for your target groups and services using the CloudWatch console or AWS CLI.

To view metrics using the CloudWatch console

1. Open the Amazon CloudWatch console at https://console.aws.amazon.com/cloudwatch/.

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

Use the following CloudWatch list-metrics AWS CLI command to list the available metrics:

aws cloudwatch list-metrics --namespace AWS/VpcLattice

For information about each of the metrics and their dimensions, see Target group metrics and Service metrics.

Target group metrics

VPC Lattice automatically stores metrics related to target groups in the AWS/VpcLattice Amazon CloudWatch namespace. For more information about target groups, see Target groups in VPC Lattice.

You may want to monitor HTTP code and RequestTime metrics for target groups. You can filter these metrics by Availability Zone (AZ) to determine which AZ the target group is in.
