Since your comments of agent - I want to clarify that my earlier question is asking for SOLR remote monitoring plugin, not fastpack. SOLR plugin is not through agent, it's pulling data via collector.
Woops - yeah didn't see the title only the summary. I have not used the plugin before. Looking at the page for it though I see you can set a port and protocol so I would just set those as you described. I don't imagine anything else would need to be done assuming the plugin still works (it seems quite old).
Not sure if this is addressed to me but on that link you can see the support level as community - we host links to some of them but do not develop them. Basically if you have to download and install a plugin it is not supported.
