In most Splunk deployments, forwarders are the components primarily responsible for supplying data for indexing. Forwarders are lightweight components installed on the machines that generate log data. Their main function is to gather data from various sources and send it to the indexers for processing and storage. This separation of duties allows for efficient data collection from multiple sources, whether they are on-premises or in the cloud.

The role of forwarders is crucial because they handle the initial data input into the Splunk environment, ensuring that log data is captured seamlessly, even from distributed systems. This structured flow of data enhances the performance and scalability of the indexing process in Splunk.

While indexers do manage data storage and search functionalities, they do not source the data directly but instead rely on forwarders to send that data to them for indexing. Search heads are primarily involved in executing search commands and generating reports based on the indexed data, rather than supplying data themselves. Distributors are less common in basic configurations and are generally used in more specialized architectures to manage the flow of data across multiple indexers.

Understanding the role of these components clarifies how data enters the Splunk ecosystem and impacts the overall deployment architecture.
