# Wildcard plugin to monitor QoS queues.
#
# Requirements:
# - tc program installed and in path
#
# Parameters supported:
#
# config
# autoconf
# suggest
#
# Configurable variables
#
# tc - Override default program
# ignore_queue<n> - Queue with handle <n> not be plotted
# label_name<n> - Queue with handle <n> as defined label
#
# Magic markers:
#%# family=manual
#%# capabilities=autoconf suggest
