Tool to compile all the changes from multiple git repository

I am looking for a tool which would pull all the changes from multiple git repositories and sort them by month and repos.

For instance:

Org: FooBarOrg
      Repo1
        change1 - Oct
        change2 - Oct
      Repo2
        Change1 - Oct
      Repo3
        Change1 - Nov

I am expecting an output like:

Oct:
  Repo1.Change1
  Repo1.Change2
  Repo2.Change1
Nov:
  Repo3.Change1

Tools I have available right now:

  • Github
  • Jira
  • confluence
  • Jenkins

If you know any plugins/tool would be very helpful

thanks,
