The following list describes the gateway metrics output by AgentCore to Amazon CloudWatch. These metrics aren't available on the CloudWatch generative AI observability page. Gateway metrics are batched at one minute intervals. To learn more about viewing gateway metrics, see View observability data for your Amazon Bedrock AgentCore agents.

Invocations

The total number of requests made to each Data Plane API. Each API call counts as one invocation regardless of the response status.

Throttles [429]

The number of requests throttled (status code 429) by the service.

SystemErrors [5xx]

The number of requests which failed with 5xx status code.

UserErrors [4xx]

The number of requests which failed with 4xx status codes other than 429.

Latency

The time elapsed between when the service receives the request and when it begins sending the first response token.

Duration

The total time elapsed between receiving the request and sending the final response token. Represents complete end-to-end processing time of the request.

TargetExecutionTime

The total time take to execute the target over Lambda, OpenAPI, etc. This metric helps you to determine the contribution of the target to the total Latency.

TargetType

The total number of requests served by each type of target (MCP, Lambda, OpenAPI).
