Atlassian needs to add a "unit of usage" to the Add-on framework, so that each Add-on application can report the number of users per month, week and per day, and the list of users that run any add-on application.

Add-on applications are not cheap, and many times we have to decide to buy one add-on over another, based on how much money we have to spend.  And we wonder if we should renew an add-on.  We'd like to make those hard decisions using actual user data.  Why should we renew an expensive add-on application, if less than 5% of the Jira usage population regularly uses it?  Or if 90% of the user population uses an add-on application multiple times per day, that add-on app should certainly be renewed.

Atlassian prepares the framework that developers use to write and publish Add-on Applications for Jira. So I believe Atlassian could add to that framework a way for the Add-on Apps to record what they consider an instant of usage, and then record that usage to the usage area of the framework. From which Atlassian could then easily publish usage of each Add-on.

For example, when I go the "Manage apps" link, the Atlassian Add-on Framework could show the number of users using this app in the last month, week, day, or hour etc, that each application has passed back to it. For each "User-Installed apps" that is listed.
There could also be a link that takes the user to the Application Usage Metric, that some charts that could indicate heavy usage over time of day, etc.
