# before trying to use this script, make sure:

#	- you have an iperf server running on the remote machine

#	- you are able to successfully run iperf from the commandline.  e.g.,

#		iperf --time 2 --parallel 4 --client $destination --format B

destination=`basename $0 | sed 's/^iperf_//g'`

	echo 'graph_category network'

	echo 'graph_period second'

	echo "graph_info This instance of iperf measures the transmit speed to $destination"

	echo 'iperf.label iperf'

	echo 'iperf.draw AREA'
