Send data via VPC Flow Logs to your Logstash instance provided by Logit.io

VPC Flow Logs

Ship logs from VPC to logstash

Step 1 - Confirm S3 Bucket

Ensure your logs are being sent to an S3 bucket. The following guide from Amazon will help you achieve this if you are not doing this already, you can choose the best way to achieve this, but cloudwatch or cloudtrail are a great place to start:

Step 2 - Ensure Adequate Bucket Permissions

The following permissions applied to the AWS IAM Policy being used:

  • s3:ListBucket to check if the S3 bucket exists and list objects in it.
  • s3:GetObject to check object metadata and download objects from S3 buckets.

Below is how your permissions should appear:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "SidID",
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:ListBucket"
             ],
            "Resource": [
                "arn:aws:s3:::your-bucket/*"
            ]
        }
    ]
 }

Step 3 - Start Sending Logs to a Stack

To start sending logs from VPC Flow to your stack you need to setup and apply an AWS input on an available stack.

Logit.io will verify your input before it is applied this should be actioned in less than 24 hours, we will contact you to verify.
