Extensions Current usage

[JoeMurray]

On Extension pages under https://civicrm.org/extensions/index, there is a Current Usage statistics, which can also be used as a sort order on https://civicrm.org/extensions. Is this from a pingback of the number of instances that have a) enabled or b) installed the extension? (I'm assuming from the name that it is not the download stat). Is it possible to break out the usage by version number?

On a separate note, when trying to fundraise for enhancements for an extension, it would be useful if there was permission to contact existing users of the extension if they had opted-in to receiving such a solicitation. What do extension developers and the core team think of this idea?

[Coleman Watts]

For native extensions this number comes from our pingback stats of enabled extensions.
For drupal modules the number comes from scraping the data from drupal.org.
I couldn't think of any way to get stats for joomla or wp plugins, so it gets reported as "unknown"

[JoeMurray]

Is it possible for extension maintainers to get a breakdown by version number as that would help in determining what sort of upgrade paths need to be supported, etc.?

[DaveFF]

Is that number going to include test/dev installations?

Yes it is possible - we are collecting that information in our pingback stats. But the code to sort and display extension useage by version would need to be written.

Is that number going to include test/dev installations?

Yes (this is true of Drupal module stats as well)
