#  disable     Stop service now, and disable start-on-boot

# Any other action word, or not specifying an action, ignores the service and skips any action.
# Similarly, any Monit service without a section is ignored.

# If the Monit definition file has a different name to the formal systemctl service,
# use the servicename directive to override it.

# Example:
# [syncthing]
# action=disable
# servicename=syncthing@openflixr
