In case a systemd unit will trigger others, a systemctl output may look like:

Triggers: ● check-mk-agent@3148-1849349-997.service
● check-mk-agent@3149-1849349-997.service

This led to falsely parsed data from the systemd status section. CPU or memory may have been mixed up between the units.

This is fixed now.
