AWS Load Balancer
This tutorial demonstrates how to collect your AWS Elastic Load Balancers, Application Load Balancers, and Network Load Balancers using Elastic Load Balancing. The data, decrypted and retaining original timestamps, is sent to Coralogix. The process is installation-free and entails simply deploying a Lambda function.
Once ingested by Coralogix, view and analyze your logs on our platform using queries, alerts, visualizations, and ML capabilities.
Prerequisites
AWS account with permissions to create Lambdas and IAM roles
An operating load balancer that writes its access log to S3
An S3 bucket clear of any triggers and with a policy that grants the load balancer permission to write access logs to the bucket
Installation
STEP 1. Navigate to Coralogix Lambda creation.
STEP 2. Fill in the required parameters.
STEP 3. Check the checkbox: "I acknowledge that this app creates custom IAM roles and resource policies."
STEP 4. Deploy.
