Does this add-on work in a clustered environment, with clustered indexers, search heads, with the data being collected by heavyweight forwarders that are updated via a deployment server?
the add-on is intended to be installed on a full Splunk instance, hence a Heavy Forwarder as teh input is via REST API (modular input)
read ore here:
i will recommend the Heavy Forwarder to be independent for these kind of inputs, meaning, not deploy those inputs via Deployment Server. if you wish, you can deploy other configurations to the Heavy Forwarder, example will be: outputs.conf
here is a link for the app and in particular to the install instructions:
hope it helps
