F.Ugly way to push TCP network stats into DataDog. Can be run from a crontab entry

	#!/bin/bash -eux
	// set $DATADOGKEY to your API key
	DATE=$(date +%s)
	HOSTNAME=`hostname`
	cat /proc/net/sockstat \| grep TCP \| cut -d":" -f2 \|sed 's/^ //g' \| awk '{print $1, $2"\n"$3, $4"\n"$5,$6"\n"$7,$8"\n"$9,$10}' > /tmp/stats.tmp

	while read LINE; do
	METRIC=$(echo $LINE \| cut -d" " -f1)
	VALUE=$(echo $LINE \| cut -d" " -f2)
	curl -X POST -H "Content-type: application/json" \
