On which components does the Splunk 6.x Dashboard Examples app need to be installed?

[chris_jepeway]

I've installed the Dashboard Examples app on our search head and our index cluster.

Did I really need to install it on the index cluster? Or is this app just for search heads?
,I've installed the Dashboard Examples app on our test search head and on our test index cluster.

Most of the examples I've looked at so far are using the _internal index, which suggests to me that there's no index peer component of the app. Does it need to be installed on the index cluster?

No, it does not. Dashboard Examples can run on the search head only.
