The component that does not belong to Splunk architecture is the controller. In Splunk's architecture, the primary components consist of the search head, indexer, and forwarder.

The search head is the interface used by users to perform searches and visualize data. It acts as the main point for querying the indexers and presenting the retrieved data to the users.

The indexer is crucial for storing and indexing the incoming data. It processes the raw data from forwarders, transforms it into an indexed format, and stores it for fast retrieval.

The forwarder is responsible for collecting and forwarding data to the indexer. There are two types of forwarders: universal forwarders, which send data to an indexer, and heavy forwarders, which can do some processing of the data before sending it to the indexers.

However, a controller is not a recognized component of Splunk architecture. Instead, it's a term that could apply to other technologies or architectures, hence its absence from the context of Splunk's specific components.
