What is Splunk Federated Search?

One might confuse this feature with Multisite Indexer Clustering; however, they are not the same. Multisite Indexer Clustering is for disaster recovery. Splunk Federated Search provides the ability to search across multiple Splunk deployments whether there are on-premises or in the Cloud.

A federated search configuration has these components:

  • Federated Search Head
  • Remote Search Head
  • Service Account
  • Federated Index

The Federated Search Head is the node where the search originates from. This search head would, for example, reside at the corporate headquarters site.

The Remote Search head is the node that receives the query request from the federated head. This search head with reside at the local office sites.

The Service Account is set up on the remote search head. It with be used at the Federated Search Head to establish communication between the Federated Search Head and Remote Search Head.

The Federate Index is created on the Federated Search Head and maps to the index names supplied by the local sites. The Remote site index name will contain the events of interest that are displayed on the Federated Search Head.
