Distributed deployments

Use the tables below to determine where and how to install this add-on in a distributed deployment of Splunk Enterprise or any deployment for which you are using forwarders to get your data in. Depending on your environment, your preferences, and the requirements of the add-on, you may need to install the add-on in multiple places.

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.

Splunk platform instance type	Supported	Required	Actions required / Comments
Search Heads	Yes	Yes	Install this add-on to all search heads where Microsoft IIS knowledge management is required.
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	See comments	This add-on supports forwarders of any type for data collection. The forwarder needs to be installed directly on the Microsoft IIS server for directory monitoring.
