Package com.pulumi.aws.cloudwatch

Class EventBus

  • public class EventBus
extends com.pulumi.resources.CustomResource
    Provides an EventBridge event bus resource. > **Note:** EventBridge was formerly known as CloudWatch Events. The functionality is identical. ## Example Usage ### Basic Usages

    ### Logging to CloudWatch Logs, S3, and Data Firehose See [Configuring logs for Amazon EventBridge event buses](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-event-bus-logs.html) for more details. #### Required Resources * EventBridge Event Bus with `logConfig` configured * Log destinations: * CloudWatch Logs log group * S3 bucket * Data Firehose delivery stream * Resource-based policy or tagging for the service-linked role: * CloudWatch Logs log group - `aws.cloudwatch.LogResourcePolicy` to allow `delivery.logs.amazonaws.com` to put logs into the log group * S3 bucket - `aws.s3.BucketPolicy` to allow `delivery.logs.amazonaws.com` to put logs into the bucket * Data Firehose delivery stream - tagging the delivery stream with `LogDeliveryEnabled = "true"` to allow the service-linked role `AWSServiceRoleForLogDelivery` to deliver logs * CloudWatch Logs Delivery: * `aws.cloudwatch.LogDeliverySource` for each log type (INFO, ERROR, TRACE) * `aws.cloudwatch.LogDeliveryDestination` for the log destination (S3 bucket, CloudWatch Logs log group, or Data Firehose delivery stream) * `aws.cloudwatch.LogDelivery` to link each log type’s delivery source to the delivery destination ### Example Usage The following example demonstrates how to set up logging for an EventBridge event bus to all three destinations: CloudWatch Logs, S3, and Data Firehose.

    ## Import ### Identity Schema #### Required * `name` (String) Name of the event bus. #### Optional * `accountId` (String) AWS Account where this resource is managed. * `region` (String) Region where this resource is managed. Using `pulumi import`, import Buses using `name` (which can also be a partner event source name). For example: ```sh $ pulumi import aws:cloudwatch/eventBus:EventBus example example-event-bus ```
