About forwarding and receiving

You can forward data from one Splunk Enterprise instance to another Splunk Enterprise instance or even to a non-Splunk system. The Splunk instance that performs the forwarding is called a forwarder.

There are several types of forwarders. See Types of forwarders to learn about each of them. To enable forwarding, see Enable forwarding on a Splunk Enterprise instance

A Splunk instance that receives data from one or more forwarders is called a receiver. The receiver is often a Splunk indexer, but can also be another forwarder.

Installation instructions

If you already know about forwarders and want the instructions on how to install them, see:

• Install a Windows universal forwarder in the Forwarder Manual.
• Install a *nix universal forwarder in the Forwarder Manual.
• Deploy a heavy forwarder

Sample forwarding layout

This diagram shows three forwarders that send data to a single receiver (an indexer), which then indexes the data and makes it available for searching:

Forwarders represent a much more robust solution for data forwarding than raw network feeds, with their capabilities for:

• Tagging of metadata (source, source type, and host)
• Configurable buffering
• Data compression
• SSL security
• Use of any available network ports

The forwarding and receiving capability makes possible all sorts of interesting topologies. You can build environments to handle functions like data consolidation, load balancing, and data routing.
