serverless-plugin-cloudwatch-sumologic

Plugin which auto-subscribes a log delivery lambda function to lambda log groups created by Serverless

Installation

npm install --save-dev serverless-plugin-cloudwatch-sumologic

Configuration

1. First follow this guide to create a new collector and http source on Sumologic.
2. Add the following custom variables to your serverless.yml file.

plugins:
  - serverless-plugin-cloudwatch-sumologic
  
custom:
    shipLogs:
        # Required
        arn: existing cloudwatch logs ARN
        # OR
        collectorUrl: Paste your url from step 1. here

        # Optional, default pattern is "[timestamp=*Z, request_id=\"*-*\", event]"
        filterPattern: "[timestamp=*Z, request_id=\"*-*\", correlation_id=\"*-*\", event]"
        role: ARN of IAM role to use

How it works

This plugin automates the process described in the readme provided by Sumologic.

Upon running sls deploy it will…

1. if no existing cloudwatch function is specified
   1. Create a temporary function in the root of your serverless project
   2. Add that function to the in-memory CloudFormation script created by the serverless framework
2. Iterate through all the functions (except for the sumologic one) and generate:
   1. CloudFormation Subscription Filter Resource linking the log groups created by serverless framework to the sumologic lambda function.
   2. Permissions to Invoke the logging function, as a Resource.
3. Wait for the stack creation/update to complete and then delete the temporarily created function source directory.

Caveats

You must be running serverless 1.25.0 or higher.
