AWS Resource Enrichment AWS Resource Enrichment

Last Updated: Dec. 21, 2023

Coralogix now offers AWS Resource Enrichment, allowing you to enrich your logs with tags from Amazon Web Services (AWS) EC2 instances. Use this feature to connect your business and operation metadata from AWS and gain greater insight into your data.

Overview

The feature enriches every log containing the following fields with metadata.

ec2_instance_id OpenTelemetry
instance_idFluentd
ec2_instance_idFluent Bit

Prerequisites

Setup

Installation & Configuration

We strongly recommend installing and configuring with OpenTelemetry. The default example below uses the configuration for OpenTelemetry.

STEP 1. Ensure your logs contain a key with EC2 instance ID value:

ec2_instance_idOpenTelemetry
instance_id (default key name) using Fluent-plugin-ec2-metadata pluginFluentD
ec2_instance_idFluent Bit

STEP 2. Add the resourcedetection and transform processors, enable the desired attributes, and add it to your config file. FluentD metadata labels and Fluent Bit metadata labels are configured differently.

You must enable host.id for the enrichment to work.

OpenTelemetry Example

processors:
  resourcedetection:
    detectors: [ec2]
    override: true
    ec2:
      resource_attributes:
        host.id:
          enabled: true
        host.name:
          enabled: true
        host.image.id:
          enabled: true
        host.type:
          enabled: true
        cloud.region:
          enabled: true
        cloud.account.id:
          enabled: true
        cloud.availability_zone:
          enabled: true
  transform:
    error_mode: ignore
    log_statements:
      - context: log
        statements:
          - set(resource.attributes["ec2_instance_id"],resource.attributes["host.id"])
          - delete_key(resource.attributes, "host.id")

Fluent Bit Example

STEP 1. Add the AWS filter with the desired additional labels.

[FILTER]
        Name aws
        Match *
        ec2_instance_type true
        account_id true
        hostname true

STEP 2. Specify the desired AWS metadata labels under the nested filter as part of the nest operation defining root fields.

[FILTER]
        Name        nest
        Match       kube.*
        Operation   nest
        Wildcard    kubernetes
        Wildcard    account_id
        Wildcard    hostname
        Wildcard    az
        Wildcard    ec2_instance_type
        Wildcard    ec2_instance_id
        Wildcard    log
        Wildcard    log_obj
        Wildcard    stream
        Wildcard    time
        Nest_under  json

AWS Lambda Deployment

STEP 1. Deploy the AWS lambda function running in your AWS account. The platform collects logs from a chosen EC2 instance in your AWS account and sends them to Coralogix, enriching them with tags associated with your instance.

STEP 2. Fill in the Application settings fields.

  • Input the Coralogix domain within which your account has been created in CoralogixRegion.
  • Input your Coralogix Send-Your-Data API key in ApiKey.
  • Do not change the default settings for the FunctionMemorySize and FunctionTimeout.

STEP 3. Deploy your application to collect tags. It will collect tags every 10 minutes and send them to Coralogix.

AWS Enrichment

STEP 1. From your Coralogix toolbar, navigate to Data Flow > Data Enrichment. Scroll down the page to view the AWS Enrichment Option.

STEP 2. Select the chosen AWS resource type.

STEP 3. Select the key with your EC2 instance ID.

resource.attributes.ec2_instance_idOpenTelemetry
ec2_instance_idFluent Bit
instance_idFluentd

Note: If you have modified the default option, you may have a different key.

STEP 4. Add the enrichment.

STEP 5. Logs associated with the chosen AWS resource should now appear enriched with AWS tags in your dashboard. To view them, navigate to Explore > Logs or to LiveTail.

Limitations

AWS Resource Enrichment feature grants the following:

  • Active resources (existing in the last 24h) / Coralogix team: 100,000
  • 50 tags/resources (equal to AWS limits)
  • Tag key length <= 127 (equal to AWS limits)
  • Tag value length <= 255 (equal to AWS limits)
