Where to install this add-on

Unless otherwise noted, all supported add-ons can be safely installed to all tiers of a distributed Splunk platform deployment. See Where to install Splunk add-ons in Splunk Add-ons for more information.

This table provides a reference for installing this specific add-on to a distributed deployment of the Splunk platform.

Search Heads	Yes	Yes	Install this add-on to all search heads where OSSEC knowledge management is required. As a best practice, turn add-on visibility off on your search heads to prevent data duplication errors that can result from running inputs on your search heads instead of or in addition to your data collection node.
Indexers	Yes	Conditional	Not required if you use heavy forwarders to collect data. Required if you use universal forwarders to collect data.
Heavy Forwarders	Yes	No	This add-on supports forwarders of any type for data collection.
