You can perform an analysis using the information of activity in the source code, issue tracker and mailing lists, so you get an idea of the history of the project and how is doing in the last term (who are the most active developers, which parts remain unmaintained, how is the activity of the user/developer mailing lists...).
Some companies/consultants offer this kind of service. For example Bitergia license their tools as open source (the MetricsGrimoire toolset, among others) so you can extract the metrics yourself, or contract them for a more comprenhensive report.
