AWS Lambda for sending logs from S3

You can send your Amazon S3 buckets to New Relic using our AWS Lambda function, NewRelic-log-ingestion-s3. This can be easily deployed from the AWS Serverless application repository.

Forwarding logs from your S3 bucket to New Relic will give you enhanced log management capabilities to collect, process, explore, query, and alert on your log data.

Install the Lambda function

To install the Lambda function to forward your S3 logs to New Relic:

  1. Make sure you have a New Relic license key.
  2. Open the AWS Serverless Application Repository in your browser.
  3. Make sure that the Lambda is installed in the same region as the S3 bucket. AWS Lambda - Select region
  4. Search for newrelic and check Show apps that create custom IAM roles or resource policies to find NewRelic-log-ingestion-s3.
  5. Click the NewRelic-log-ingestion-s3 details and click Deploy.
  6. Scroll to the Application settings and enter your New Relic license key].
  7. Take advantage of New Relic's log parsing capabilities by specifying the logtype as an environment variable for the Lambda function. For more information, see Built-in parsing rulesets.
  8. Confirm that the app creates custom IAM roles, and then click Deploy.
  9. Once the function is deployed, create a Lambda trigger.

Manual install using Serverless Framework

You can manually install and configure the Lambda from the terminal using the Serverless Framework. If you're not on Linux, install Docker first and keep it running.

# Clone the repository
git clone https://github.com/newrelic/aws_s3_log_ingestion_lambda.git
# Install Serverless and the repo dependencies
npm install -g serverless
npm install
# Set the New Relic License Key env variable
export LICENSE_KEY=YOUR_NEWRELIC_LICENSE_KEY
# Set the logtype (optional)
export LOG_TYPE=YOUR_LOGTYPE
# Set the S3 bucket name
export S3_BUCKET_NAME=YOUR_S3_BUCKET_NAME
# The S3 subdirectory (optional)
export S3_PREFIX=YOUR_S3_SUBDIRECTORY
# Choose a name for your new Serverless Framework service
export SERVICE_NAME=YOUR_SERVICE_NAME
# Deploy the function, specifying the same region as your S3 bucket listed above
serverless deploy --region YOUR_AWS_REGION

Create a Lambda trigger in AWS

To get your logs streaming to New Relic, attach a trigger to the Lambda:

  1. In the left side menu, click Functions.
  2. Find and select the previously created NewRelic-s3-log-ingestion function.
  3. Under Designer, click Add Triggers and select S3 from the dropdown.
  4. Select the S3 bucket that contains the log you want to send to New Relic.
  5. Optionally configure a prefix and suffix. This is helpful if your logs are in a subdirectory.
  6. Check the Enable trigger checkbox, then Add the trigger.

To test the Lambda function, upload a new log file to the S3 bucket you configured in the function settings and then view your log data.
