Configure Config inputs for the Splunk Add-on for AWS

Configure the Splunk Add-on for AWS to ingest Config inputs.

Best practices for configuring inputs

  • Configure SQS-based S3 inputs to collect AWS data.
  • Configure an AWS Config input for the Splunk Add-on for Amazon Web Services on your data collection node through Splunk Web. This data source is only available in a subset of AWS regions, which does not include China. See the AWS documentation for a full list of supported regions.
  • Configure a single enabled Config modular input for each unique SQS. Multiple enabled modular inputs can cause conflicts when trying to delete SQS messages or S3 records that another modular input is attempting to access and parse.
  • Be sure to disable or delete testing configs before releasing your configuration in production.

Configure a Config input using Splunk Web

To configure inputs using Splunk Web, click Splunk Add-on for AWS in the left navigation bar on Splunk Web home, then click Create New Input > Config > Config. Fill out the fields as described in the table:

Field in Splunk Web Description
AWS Account The AWS account or EC2 IAM role the Splunk platform uses to access your Config data. In Splunk Web, select an account from the drop-down list.
AWS Region The AWS region that contains the log notification SQS queue. Enter the region ID. See the AWS documentation for more information.
SQS queue name The name of the queue to which AWS sends new Config notifications. Select a queue from the drop-down list, or enter the queue name manually. The queue name is the final segment of the full queue URL. For example, if your SQS queue URL is http://sqs.us-east-1.amazonaws.com/123456789012/testQueue, then your SQS queue name is testQueue.
Source type A source type for the events. Enter a value only if you want to override the default of aws:config. Event extraction relies on the default value of source type. If you change the default value, you must update props.conf as well.

Note that the Splunk platform indexes AWS Config events using three variations of this source type:

  • Configuration snapshots are indexed as sourcetype=aws:config.
  • Configuration change notifications are indexed as sourcetype=aws:config:notification.
  • Logs from aws_config.log are indexed as sourcetype=aws:config:log.
Index The index name where the Splunk platform puts the Config data. The default is main.
Interval The number of seconds to wait before the Splunk platform runs the command again. Default is 30 seconds.

Configure a Config input using configuration files

To configure inputs manually in inputs.conf, create a stanza using the following template and add it to $SPLUNK_HOME/etc/apps/Splunk_TA_aws/local/inputs.conf. If the file or path does not exist, create it.

aws_account = <value>
aws_region = <value>
sqs_queue = <value>
interval = <value>
sourcetype = <value>
index = <value>

Some of these settings have default values that can be found in $SPLUNK_HOME/etc/apps/Splunk_TA_aws/default/inputs.conf:

aws_account =
sourcetype = aws:config
queueSize = 128KB
persistentQueueSize = 24MB
interval = 30 

The values above correspond to the default values in Splunk Web as well as some internal values that are not exposed in Splunk Web for configuration. If you choose to copy this stanza to /local and use it as a starting point to configure your inputs.conf manually, change the stanza title from aws_config to aws_config://<name> and add the additional parameters that you need.
