Amazon S3 Destination

The Amazon S3 destination is available for the Archive Logs template. Use this destination to send your logs in Datadog-rehydratable format to an Amazon S3 bucket for archiving. You need to set up Datadog Log Archives if you haven’t already, and then set up the destination in the pipeline UI.

Configure Log Archives

If you already have a Datadog Log Archive configured for Observability Pipelines, skip to Set up the destination for your pipeline.

You need to have Datadog’s AWS integration installed to set up Datadog Log Archives.

  3. Enter a descriptive archive name.

Set up the destination for your pipeline

Set up the Amazon S3 destination and its environment variables when you set up an Archive Logs pipeline. The information below is configured in the pipelines UI.

  1. Enter the S3 bucket name for the S3 bucket you created earlier.
  2. Enter the AWS region the S3 bucket is in.
  3. Enter the key prefix.
    • Prefixes are useful for partitioning objects. For example, you can use a prefix as an object key to store objects under a particular directory. If using a prefix for this purpose, it must end in / to act as a directory path; a trailing / is not automatically added.
    • See template syntax if you want to route logs to different object keys based on specific fields in your logs.
  4. Select the storage class for your S3 bucket in the Storage Class dropdown menu.

Your AWS access key ID and AWS secret access key are set as environment variables when you install the Worker later.

Set the environment variables

Enter the AWS access key ID and AWS secret access key for the S3 archive bucket you created earlier.
