AWS Load Balancer

Coralogix allows an easy way to collect your AWS load balancer (ELB, ALB, NLB) logs while decrypting them and using their original timestamp without you having to install anything on your environment, but simply deploying a Lambda. 

AWS Load Balancer logs are written by AWS to S3, in order to ship them into Coralogix and enjoy our queries, alerts, visualizations, and ML capabilities, you should read the log data bucket using our proprietary Lambda.  

Usage

Make sure you add the following environment variables when using this lambda.

NameDescription
private_keyA private key which is used to validate your authenticity, this key will be sent to your mail once you register to Coralogix and should not be transferred outside your company
app_nameThe name of your main application, for example, a company named “SuperData” would probably insert the “SuperData” string parameter or if they want to debug their test environment they might insert the “SuperData– Test”
sub_nameYour application probably has multiple subsystems, for example, Backend servers, Middleware, Frontend servers etc. in order to help you examine the data you need, inserting the subsystem parameter is vital

1. Create an “author from scratch” Node.js 8.10 runtime lambda with an S3 read permissions 

logs from S3 to Coralogix

2. At “Code entry type” choose “Upload a ZIP file” and upload “s3ToCoralogixELB.zip”

3. Add the mandatory environment variables: private_key, app_name, sub_name

4. Choose the S3 bucket you want to get triggered by and change the event type from “PUT” to “Object Created(All)”

6. Multiline pattern: Coralogix supports multiline pattern by default, you can define a custom pattern with an environment variables, for example: newline_pattern [\s(?={)|(?<=})\s,\s(?={)|(?<=})\s\].

7. Increase Memory to 1024mb and Timeout to 30 sec.
