At start systemd_mon i get this messages in log

last two strings - i think for two monitored services

I'm also seeing this. It seems to be due to the services already being up and running when systemd_mon is started, and it also only seems to happen the very first time systemd_mon is run.

It's probably a straightforward issue with just needing to initialize 'first' somewhere, but I'm not that familiar with ruby or I would take a stab at it.
