# PROVIDE: yabm 
# REQUIRE: NETWORKING 
# KEYWORD: FreeBSD shutdown
#
# 
# Add the following to your /etc/rc.conf to enable yabm
# 
# yabm_enable="YES"
#
# Then, for each interface you want to monitor you add the following, where the 
# number 0 has to be increased for each interface
# Example
# yabm_if0="fxp0"
# yabm_if0_output="/path/to/image.png"
# yabm_if0_flags="-m 512k -t"
#
# Monitoring ip-aliases is like monitoring interfaces except the keyword
# alias is used instead of if
# Example
# yabm_alias0="192.168.0.7"
# yabm_alias0_output="/path/to/image2.png"
# yabm_alias0_flags=""
#
#
# DO NOT CHANGE OR SET ANY VALUES IN THIS FILE
