There are two main tools which aggregate altmetrics from a wide variety of different websites and online tools (listed in alphabetical order):
Altmetric gathers article level metrics for papers, and provides altmetric data for publishers, institutions and researchers.
It requires a subscription, but Altmetric widgets are included in some databases and eJournals, such as Nature.
You can also use the free Altmetric bookmarklet to view altmetric information for any online article with a DOI.

Plum Analytics collects impact metrics in 5 categories: captures, usage, citations, mentions, and social media, for over 20 different types of artifacts including: journal articles, books, videos, presentations, datasets, source code, and more.
It collects metrics for individual research artifacts, but also for labs, departments and other groups.
This product requires a subscription and the Mayo Clinic currently does not have a subscription to this product. However, PlumX Metrics icons will appear in the library’s EBSCO databases, including CINAHL beginning in 2016.
