About the Splunk OVA for VMware Metrics
The Splunk OVA for VMware Metrics is a preconfigured virtual machine with a lightweight operating system, Splunk heavy forwarder and all necessary add-ons and supporting add-ons to collect performance, inventory, tasks and event data from VMWare vCenter servers. The Splunk OVA for VMware Metrics deploys as a Data Collection Node (DCN) to collect data for the Splunk App for Infrastructure (SAI).
VMware vCenter Servers and resources, including data centers, clusters, ESXi hosts, and virtual machines appear as entities in Splunk App for Infrastructure when you start monitoring a vCenter Server with a DCN. You can integrate SAI entities in ITSI to create ITSI services from the SAI entities.
DCNs are required components for any Splunk Add-on for VMware Metrics deployment. If you can't deploy an OVA, you can manually configure a Splunk heavy forwarder to perform as a DCN. For more information, see Configure a heavy forwarder to be a DCN in the Splunk Add-on for VMware Metrics manual.
