# IBedrockAgentRuntime

Interface for Agent Runtime resources.

Extends: IBedrockAgentRuntime
Extends: IResource, IGrantable, IConnectable, IRuntimeRef
Implemented by: Runtime, RuntimeBase

- Source: [`aws-bedrockagentcore/lib/runtime/runtime-base.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0/packages/aws-cdk-lib/aws-bedrockagentcore/lib/runtime/runtime-base.ts#L63)
- Type last changed: v2.258.0 · 4 Jun 2026

## Properties

- `agentRuntimeArn`: string — The ARN of the agent runtime resource - Format `arn:${Partition}:bedrock-agentcore:${Region}:${Account}:runtime/${RuntimeId}`.

  ```ts
  "arn:aws:bedrock-agentcore:us-west-2:123456789012:runtime/runtime-abc123"
  ```

- `agentRuntimeId`: string — The ID of the agent runtime.

  ```ts
  "runtime-abc123"
  ```

- `agentRuntimeName`: string — The name of the agent runtime.

- `agentRuntimeVersion`: string — The version of the agent runtime.

- `agentStatus`: string — The current status of the agent runtime.

- `applicationLogGroup`: [ILogGroup](/cdk/api/v2/docs/aws-cdk-lib.aws_logs.ILogGroup.html) — The CloudWatch Logs application log group for the default endpoint of this runtime, located at `/aws/bedrock-agentcore/runtimes/{agentRuntimeId}-DEFAULT`.

  Use this
  property to attach metric filters, subscription filters, or alarms to the log
  group without hardcoding its name.

  The log group is created by the AgentCore service on the runtime's first
  invocation, not by CDK. Constructs that require the log group to exist at
  deploy time (such as `MetricFilter`) may race the first invocation; in that
  case, ensure at least one invocation has occurred before deploying the
  dependent resources, or pre-create the log group with a `LogRetention`
  custom resource using the same name.

  ```ts
  "/aws/bedrock-agentcore/runtimes/runtime-abc123-DEFAULT"
  ```

- `connections`: [Connections](/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.Connections.html) — The network connections associated with this resource.

- `createdAt`: string — The time at which the runtime was created.

  ```ts
  "2024-01-15T10:30:00Z"
  ```

- `env`: [ResourceEnvironment](/cdk/api/v2/docs/aws-cdk-lib.interfaces.ResourceEnvironment.html) — The environment this resource belongs to.

  For resources that are created and managed in a Stack (those created by
  creating new class instances like `new Role()`, `new Bucket()`, etc.), this
  is always the same as the environment of the stack they belong to.

  For referenced resources (those obtained from referencing methods like
  `Role.fromRoleArn()`, `Bucket.fromBucketName()`, etc.), they might be
  different than the stack they were imported into.

- `grantPrincipal`: [IPrincipal](/cdk/api/v2/docs/aws-cdk-lib.aws_iam.IPrincipal.html) — The principal to grant permissions to.

- `lastUpdatedAt`: string — The time at which the runtime was last updated.

  ```ts
  "2024-01-15T14:45:00Z"
  ```

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) — The tree node.

- `role`: [IRole](/cdk/api/v2/docs/aws-cdk-lib.aws_iam.IRole.html) — The IAM role that provides permissions for the agent runtime.

- `runtimeRef`: [RuntimeReference](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_bedrockagentcore.RuntimeReference.html) — A reference to a Runtime resource.

- `stack`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html) — The stack in which this resource is defined.

## Methods

- `addToRolePolicy(statement: PolicyStatement): IBedrockAgentRuntime // chainable` — Adds a policy statement to the runtime's execution role.

  **Parameters**

  - `statement` — The IAM policy statement to add.

  **Returns:** The runtime instance for chaining

- `applyRemovalPolicy(policy: RemovalPolicy): void` — Apply the given removal policy to this resource.

  The Removal Policy controls what happens to this resource when it stops
  being managed by CloudFormation, either because you've removed it from the
  CDK application or because you've made a change that requires the resource
  to be replaced.

  The resource can be deleted (`RemovalPolicy.DESTROY`), or left in your AWS
  account for data recovery and cleanup later (`RemovalPolicy.RETAIN`).

- `grant(actions: string[], resources: string[]): Grant` — Grant the runtime specific actions on AWS resources.

  **Parameters**

  - `actions` — The actions to grant.
  - `resources` — The resource ARNs to grant access to.

  **Returns:** The Grant object for chaining

- `grantInvoke(grantee: IGrantable): Grant` — Permits an IAM principal to invoke this runtime both directly and on behalf of users Grants both bedrock-agentcore:InvokeAgentRuntime and bedrock-agentcore:InvokeAgentRuntimeForUser permissions.

  **Parameters**

  - `grantee` — The principal to grant access to.

- `grantInvokeRuntime(grantee: IGrantable): Grant` — Permits an IAM principal to invoke this runtime Grants the bedrock-agentcore:InvokeAgentRuntime permission.

  **Parameters**

  - `grantee` — The principal to grant access to.

- `grantInvokeRuntimeForUser(grantee: IGrantable): Grant` — Permits an IAM principal to invoke this runtime on behalf of a user Grants the bedrock-agentcore:InvokeAgentRuntimeForUser permission Required when using the X-Amzn-Bedrock-AgentCore-Runtime-User-Id header.

  **Parameters**

  - `grantee` — The principal to grant access to.

- `metric(metricName: string, props?: MetricOptions): Metric` — Return the given named metric for this agent runtime.

- `metricInvocations(props?: MetricOptions): Metric` — Return a metric containing the total number of invocations for this agent runtime.

- `metricInvocationsAggregated(props?: MetricOptions): Metric` — Return a metric containing the total number of invocations across all resources.

- `metricLatency(props?: MetricOptions): Metric` — Return a metric measuring the latency of requests for this agent runtime.

- `metricSessionCount(props?: MetricOptions): Metric` — Return a metric containing the number of agent sessions for this agent runtime.

- `metricSessionsAggregated(props?: MetricOptions): Metric` — Return a metric containing the total number of sessions across all resources.

- `metricSystemErrors(props?: MetricOptions): Metric` — Return a metric containing the number of system errors for this agent runtime.

- `metricThrottles(props?: MetricOptions): Metric` — Return a metric containing the number of throttled requests for this agent runtime.

- `metricTotalErrors(props?: MetricOptions): Metric` — Return a metric containing the total number of errors (system + user) for this agent runtime.

- `metricUserErrors(props?: MetricOptions): Metric` — Return a metric containing the number of user errors for this agent runtime.

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.

  **Parameters**

  - `mixins` — The mixins to apply.

  **Returns:** This construct for chaining
