This was tested with FusionPBX 4.5.1 (current master at time of writing) and will likely work on newer or slightly older versions of FusionPBX.
Clone the FusionPBX-Apps repo into the working path after SSHing/Moshing into your server:
git clone https://github.com/fusionpbx/fusionpbx-apps.git
cd /var/www/fusionpbx/app
cp -r ~/fusionpbx-apps/domain_counts .
Alternative (and preferred) commands to run in SSH session:
cd /usr/src
git clone https://github.com/fusionpbx/fusionpbx-apps
cp -R /usr/src/fusionpbx-apps/domain_counts /var/www/fusionpbx/app
chown -R www-data:www-data /var/www/fusionpbx/app/domain_counts
Then navigate to your FusionPBX installation and choose Advanced => Upgrade. Run upgrades for Menu Defaults and for Permission Defaults.
Log out and back into your FusionPBX installation. Go to Status => Domain Counts.
