# mnrpes_scheduler startup script
#
# PROVIDE: mnrpes_scheduler
# REQUIRE: LOGIN
# KEYWORD: shutdown
#
# Add the following to /etc/rc.conf[.local] to enable this service
#
# mnrpes_scheduler_enable="YES"
#
# You can fine tune others variables too:
# mnrpes_scheduler_config=
# mnrpes_scheduler_checks=
# Use mnrpes_scheduler_user to run mnrpes_scheduler as user

# mnrpes_scheduler rc.d script supports multiple profiles (a-la rc.d/nginx)
# When profiles are specified, the non-profile specific parameters become defaults.
#
# Example:
#
# mnrpes_scheduler_enable="YES"
# mnrpes_scheduler_profiles="myserver myotherserver"
# mnrpes_scheduler_config="/usr/local/etc/mnrpes/mnrpes-scheduler.cfg"
# mnrpes_scheduler_checks="/usr/local/etc/mnrpes/checks.txt"
# mnrpes_scheduler_myserver_user="myuser"
# mnrpes_scheduler_myotherserver_user="myotheruser"
# mnrpes_scheduler_myotherserver_config="/usr/local/etc/mnrpes/mnrpes-scheduler-myotherserver.cfg"
# mnrpes_scheduler_myotherserver_checks="/usr/local/etc/mnrpes/checks-myotherserver.txt"
