### BEGIN INIT INFO
# Provides: mrtg
# Required-Start: $network
# Required-Stop: $network
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Starts the The Multi Router Traffic Grapher
# Description: The Multi Router Traffic Grapher is a tool primarily used to
# monitor the traffic load on network links (typically by using
# SNMP). MRTG generates HTML pages containing PNG images which
# provide a LIVE visual representation of this traffic. MRTG
# typically produces daily, weekly, monthly, and yearly graphs.
