S3 Log Collection S3 Log Collection

Last Updated: Mar. 30, 2022

One of the easiest ways to collect logs is to send all of them to S3 buckets.
We aim to help and make the log collection a breeze so we have An application published in AWS’s 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

Deploying this lambda with Terraform

We realize your infrastructure is rapidly growing.

You may wish to replicate this lambda or simply have multiple deployments managed as code.

We provide a terraform example just for that. You can find the Terraform module on GitHub
