Amazon Web Services (AWS) CloudFormation Logs

Send your logs to Coralogix using AWS CloudFormation, granting you observability into your CloudFormation events.

The following tutorial demonstrates how to configure an AWS CloudFormation template using a Lambda function to send your telemetry data to Coralogix.

Prerequisites

1. Sign up for a Coralogix account. Set up your account on the Coralogix domain corresponding to the region within which you would like your data stored.

2. Access your Coralogix private key.

3. Create an active AWS account with permissions to manage Lambda functions. Log in to your account as administrator.

4. Save the script for the AWS CloudFormation template on your desktop or in an S3 bucket.

Configuration

Create a Stack

Navigate to CloudFormation Page and click Create Stack (with new resources).

Note! AWS CloudFormation may create IAM resources.

2. Under the Stack option tab, select Template is ready. Upload a .yaml file from your S3 bucket or desktop, as in the example below.
