# If the plugin is run as root it will update the vnStat database before getting

# the stats.

# - quick an ddirty update to support multiple interfaces, for example symlink vnstat_ to vnstat_eth0 and vnstat_eth1

# rember to run before that vnstat -u -i eth0 and vnstat -u -i eth1 to build databases (read manual of vnstat)

# other updates of this script maybe soon
