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.

Recommended deployment

While it is possible to use the add-on to poll remote JMX management servers, Splunk recommends installing this add-on on a heavy forwarder that is installed on the same host as the central JMX server. This deployment configuration simplifies your configuration because you can call the port locally, you do not need to use certificates, and you can use the Java version that is local to the machine.

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 JMX knowledge management is required.
Indexers	Yes	No	Not required, as the parsing operations occur on the heavy forwarders.
Heavy Forwarders	Yes	Yes	This add-on requires heavy forwarders to perform data collection.
Universal Forwarders	No	No	This add-on requires heavy or light forwarders.

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	Yes	You can install this add-on on a search head cluster for all search-time functionality, but only configure inputs on forwarders to avoid duplicate data collection. Before installing this add-on to a cluster, make the following changes to the add-on package: 1. Remove the inputs.conf file.
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-on only. Using a deployment server to deploy the configured add-on to multiple forwarders acting as data collectors causes duplication of data.
