I have created several dashboards for different applications I support, but because I have many different groups of servers per application, I would like to generate the same kinds of dashboards, but based on different servers. Does Splunk have another way based on templates to do the same thing?
You can create a dashboard panel and add it to a dashboard by reference. That wouldn't give you a single dashboard template, but it would allow you to keep a library of panels that you could use and then modify.
i am not sure i completely understand the question but in the case the data is the same format, you can clone the dashboards and then modify the searches that runs the dashboards to match new server names
