Monitoring employees contribute at project

We can install git self-hosted (like Gitlab, Googs etc) so we can login as admin then mask-"login" as employess. But If we use git cloud we can use git log or git shortlog, gitstats, git-fame etc.

==================================
GIT LOG
==================================
Show commit by author specific date
$ git shortlog -sne --since="01 Feb 2018" --before="01 Mar 2018"

Example:

    77  Bondowoso <me.woso@gmail.com>

    13  Jonggrang <jonggrang@gmail.com>

==================================
GITSTATS
==================================

Install:
$ sudo apt update
$ sudo apt install gitstats

Run:
$ gitstats /path/to/project /path/to/result

Example:
$ gitstats /home/en/sdk-chat-android /home/en/Downloads/android
Open index.html at /home/en/Downloads/android/index.html

=================================
GIT-FAME
=================================
Install:
$ pip install --user git-fame
$ cd /path/to/project
$ git-fame
