Install the Splunk Add-on for F5 BIG-IP

1. Get the Splunk Add-on for F5 BIG-IP by downloading it from Splunkbase or browsing to it using the app browser within Splunk Web.
2. Determine where and how to install this add-on in your deployment using the following tables on this page.
3. Perform any prerequisite steps before installing, if required and specified in the following tables.
4. Complete your installation.

If you need step-by-step instructions on how to install an add-on in your specific deployment environment, see the installation walkthroughs section for links to installation instructions specific to a single-instance deployment, distributed deployment, Splunk Cloud, or Splunk Light.

Distributed deployments

Use the tables below to determine where and how to install this add-on in a distributed deployment of Splunk Enterprise.

Where to install this add-on

This table provides a quick reference for installing this add-on to a distributed deployment of Splunk Enterprise.

Splunk instance type	Supported	Required	Comments
Search Heads	Yes	Yes	Install this add-on to all search heads where F5 knowledge management is required. Turn 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) on your data collection node.
Indexers	Yes	Conditional	Not required, as the parsing operations occur on the heavy forwarders. If you do not want to collect any iControl data and install the add-on to light or universal forwarders instead, install this add-on to your indexers as well.
Heavy Forwarders	Yes	Conditional	This add-on requires heavy forwarders to perform data collection via modular inputs and for configuration via Splunk Web.
Universal Forwarders	Conditional	No	The modular input in this add-on requires heavy forwarders. If you do not want to collect any iControl data via modular input, you can use a universal or light forwarder instead, as only the modular input requires Python and Splunk Web for configuration.

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	Conditional	You can install this add-on on a search head cluster for all search-time functionality, but only configure inputs on a forwarder (ie. a non-clustered search head) to avoid duplicate data collection.
Indexer Clusters	Yes
Deployment Server	Conditional	If you are not using the modular input, the deployment server is supported. If you are collecting iControl data using modular inputs, the deployment server is supported for deploying unconfigured add-ons only. Using a deployment server to deploy the configured add-on to multiple forwarders acting as data collectors causes duplication of data. The add-on uses the credential vault to secure your credentials, and this credential management solution is incompatible with the deployment server.
