Amazon Elastic File System

Overview

Amazon EFS provides simple, scalable file storage for use with AWS Lambda functions or Amazon EC2 instances.

Enable this integration to collect all your EFS 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 page, ensure that EFS is enabled under the Metric Collection tab.

  2. Add those permissions to your Datadog IAM policy in order to collect Amazon EFS metrics:

    • elasticfilesystem:DescribeTags: Gets custom tags applied to file systems
    • elasticfilesystem:DescribeFileSystems: Provides a list of active file systems

    For more information, see the EFS policies on the AWS website.

  3. Install the Datadog - AWS EFS integration.

Log collection

Enable logging

Configure Amazon EFS to send logs either to a S3 bucket or to CloudWatch.

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

Send logs to Datadog

  1. If you haven’t already, set up the Datadog Forwarder 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 EFS logs in the AWS console:

Amazon EFS for Lambda

Amazon EFS for Lambda allows you to connect an EFS to your Lambda functions. Organizations can use EFS for Lambda to simplify their machine learning and data processing workloads to be entirely serverless. To divide Lambda metrics and logs by EFS:

  1. Install the AWS Lambda integration and enable metric collection.

  2. Add this permission to your Datadog IAM policy:

    • elasticfilesystem:DescribeAccessPoints: Lists active EFS connected to Lambda functions
