  3. Perform any prerequisite steps before installing, if required and specified in the tables below.

Distributed deployment feature compatibility

This table provides a quick reference for the compatibility of this add-on with Splunk distributed deployment features.

Distributed deployment feature Supported Comments
Search Head Clusters Yes You can install this add-on on a search head cluster for all search-time functionality, but configure inputs on forwarders to avoid duplicate data collection.

Before you install this add-on to a cluster, remove the eventgen.conf file and all files in the samples folder.

Indexer Clusters Yes Before you install this add-on to a cluster, remove the eventgen.conf file and all files in the samples folder.
Deployment Server Yes Supported for deploying the configured add-on to multiple nodes. This is a Splunk best practice and the Splunk Apps for Microsoft Exchange and Windows Infrastructure use a deployment server to facilitate easier installation.
