S3 Log Collection S3 Log Collection

Last Updated: Jan. 22, 2023

One of the easiest ways to collect logs is to send all of them to S3 buckets.
To make the log collection a breeze, use our app in the AWS Serverless Application Repository.


  • You need to have a ready-made S3 bucket.
  • The bucket should be clear of any Lambda triggers.
  • Your AWS user should have permissions to create lambdas and IAM roles.


  • Navigate to: Application Page
  • Fill in the required parameters
  • be sure to check the checkbox labeled as
    I acknowledge that this app creates custom IAM roles and resource policies.
  • Click Deploy

Once the deployment is done every new gzipped log file placed in the lambda will be sent to Coralogix
