1. Get the Splunk Add-on for ServiceNow by downloading it from Splunkbase or browsing to it using the app browser within Splunk Web.
2. Use the tables on this page to determine where and how to install this add-on in your deployment.
3. Perform any prerequisite steps before installing.
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 at the bottom of this page for links to installation instructions specific to a single-instance deployment, distributed deployment, Splunk Cloud, or Splunk Light.

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.

Splunk platform instance type	Supported	Required	Actions required/Comments
Search Heads	Yes	Yes	Install this add-on to all search heads where ServiceNow knowledge management is required. This add-on contains optional search-time interactions. If you want Splunk platform users to be able to create incidents or events in ServiceNow from the Splunk platform, make the following changes to the add-on package and perform the add-on setup on the search heads to configure your ServiceNow credentials: Add stanzas to your inputs.conf file, using the inputs.conf.spec file in the $SPLUNK_HOME/etc/apps/Splunk_TA_snow/README folder of the add-on package as a reference.
Indexers	Yes	No	Not required, because the parsing operations occur on the heavy forwarders.
Heavy Forwarders	Yes	Yes	This add-on supports only heavy forwarders for data collection.
Universal Forwarders	No	No

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	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. If you want Splunk platform users to be able to create incidents or events in ServiceNow from the Splunk platform, make the following changes to the add-on package and perform the add-on setup on the search heads to configure your ServiceNow credentials: 1. Add the inputs.conf.spec file in the $SPLUNK_HOME/etc/apps/Splunk_TA_snow/README folder of the add-on package.
Indexer Clusters	Yes	Before installing this add-on to a cluster, make the following changes to the add-on package: 1. Remove the inputs.conf 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. The add-on uses the credential vault to secure your credentials, and this credential management solution is incompatible with the deployment server.
