1. Get the Splunk Add-on for Citrix NetScaler 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 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 following installation walkthrough section for links to installation instructions specific to a single-instance deployment, distributed deployment, or Splunk Cloud.

Distributed deployments

Use the following tables 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 Splunk Enterprise.

Splunk instance type	Supported	Required	Actions required / Comments
Search Heads	Yes	Yes	Install this add-on to all search heads where Citrix NetScaler knowledge management is required. Splunk recommends that you 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) on 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	See comments	Required for modular inputs. If you are not using the NITRO API modular inputs, any forwarder type is supported.
Universal Forwarders	Yes	See comments	Supported for IPFIX and UDP inputs only.

Distributed deployment feature compatibility

This table describes the compatibility of this add-on with Splunk distributed deployment features.

Distributed deployment feature	Supported	Actions required
Search Head Clusters	Yes	Disable add-on visibility on search heads. 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 installing this add-on to a cluster: if the inputs.conf file is present in your installation package, remove the file.
Indexer Clusters	Yes	Before installing this add-on to a cluster: if the inputs.conf file is present in your installation package, remove the file.
Deployment Server	No	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.
