The template and application relationship

The following illustration explains how templates and applications relate and is true for all templates, including AppInsight applications.

If you change a configuration setting or component monitor at the template level, the applications based on that template are affected. Conversely, if you change a setting at the application level, only that application is affected. This inheritance relationship is beneficial if you need to make many changes quickly.

For example, rather than change one item on 100 applications that are based on a single template (which requires 100 changes), you can change the one item on the template, then that one change trickles down to all applications based on the template.
