Overview

Amazon Elastic MapReduce (Amazon EMR) is a web service that makes it easy to quickly and cost-effectively process vast amounts of data.

Enable this integration to see EMR metrics in Datadog.

Setup

Installation

If you haven’t already, set up the Amazon Web Services integration first.

Metric collection

  1. In the AWS integration tile, ensure that EMR is checked under metric collection.
  2. Add the following permissions to your Datadog IAM policy to collect Amazon EMR metrics. For more information on EMR policies, review the documentation on the AWS website.

    AWS PermissionDescription
    elasticmapreduce:ListClustersList available clusters.
    elasticmapreduce:DescribeClusterAdd tags to CloudWatch EMR metrics.
  3. Install the Datadog - AWS EMR integration.

Log collection

Enable logging

Configure Amazon EMR to send logs either to a S3 bucket or to Cloudwatch.

Note: If you log to a S3 bucket, make sure that amazon_emr is set as Target prefix.

Send logs to Datadog

  1. If you haven’t already, set up the Datadog log collection AWS Lambda function.
  2. Once the lambda function is installed, manually add a trigger on the S3 bucket or Cloudwatch log group that contains your Amazon EMR logs in the AWS console:
