Release notes for the Splunk Add-on for AWS

Version 7.6.0 of the Splunk Add-on for Amazon Web Services was released on April 2, 2024.

Billing (Legacy) input is deprecated in add-on version 7.6.0. Please configure Billing (Cost and Usage Report) inputs to collect billing data.

Starting in version 7.1.0 of the Splunk Add-on for AWS, the file based checkpoint mechanism was migrated to the Splunk KV Store for Billing Cost and Usage Report, CloudWatch Metrics, and Incremental S3 inputs. The inputs must be disabled whenever the Splunk software is restarted. Otherwise, it will result in data duplication against your already configured inputs.

Version 7.0.0 of the Splunk Add-on for AWS includes a merge of all the capabilities of the Splunk Add-on for Amazon Security Lake. Configure the Splunk Add-on for AWS to ingest across all AWS data sources for ingesting AWS data into your Splunk platform deployment.

If you use both the Splunk Add-on for Amazon Security Lake as well as the Splunk Add-on for AWS on the same Splunk instance, then you must uninstall the Splunk Add-on for Amazon Security Lake before upgrading the Splunk Add-on for AWS to version 7.0.0 or later in order to avoid any data duplication and discrepancy issues.

Version 6.0.0 of the Splunk Add-on for AWS includes a merge of all the capabilities of the Splunk Add-on for Amazon Kinesis Firehose. Configure the Splunk Add-on for AWS to ingest across all AWS data sources for ingesting AWS data into your Splunk platform deployment.

If you use both the Splunk Add-on for Amazon Kinesis Firehose as well as the Splunk Add-on for AWS on the same Splunk instance, then you must uninstall the Splunk Add-on for Amazon Kinesis Firehose after upgrading the Splunk Add-on for AWS to version 6.0.0 or later in order to avoid any data duplication and discrepancy issues.

Data that you previously onboarded through the Splunk Add-on for Amazon Kinesis Firehose will still be searchable, and your existing searches will be compatible with version 6.0.0 of the Splunk Add-on for AWS.

If you are not currently using the Splunk Add-on for Amazon Kinesis Firehose, but plan to use it in the future, then the best practice is to download and configure version 6.0.0 or later of the Splunk Add-on for AWS, instead of the Splunk Add-on for Amazon Kinesis Firehose.
