Replace the systemd unit files that needed to be modified for a specific interface with template files. The template files allows one to instansiate a service for any interface (by running systemctl start pping@<interface>.service), and multiple interfaces can be monitored at once. Each instance maintains a separtate "log" of data at /sys/var/log/pping/<interface>/pping.<interface>.json which is rotated one per minute (see the [email protected] file) and placed in daily subfolders.
