Log AgentCore Web Search API calls with AWS CloudTrail
AWS CloudTrail records InvokeWebSearch requests as data events with the event name InvokeWebSearch, the event source bedrock-agentcore.amazonaws.com, and the resource type AWS::BedrockAgentCore::WebSearch. Each event lists the web search tool that the request named as its resource.
By default, CloudTrail doesn’t log data events, and they don’t appear in CloudTrail Event history. To record InvokeWebSearch requests, create a trail or event data store and add an advanced event selector for the AWS::BedrockAgentCore::WebSearch resource type.
CloudTrail records each request that Amazon Bedrock AgentCore authenticates. These include requests that are throttled, that an AWS Identity and Access Management (IAM) policy denies, or that have a field that isn’t valid. CloudTrail doesn’t record a request that is rejected before authentication, such as a request that is unsigned, that fails authentication, or whose body is too large. It also doesn’t record a request that only a virtual private cloud (VPC) endpoint policy denies. For an AccessDeniedException, the event’s errorCode is AccessDenied.
The requestParameters field of an event holds only webSearchId and, if the request sets it, maxResults. CloudTrail doesn’t record the search text or the filters.
