feature request : statsd porting about tsar

[kongjian]

tsar -l -i 1 caused high cpu usage?

[feng92f]

I change code to make tsar -l -i 1 to print metrics line by line ,and send via nc(udp).

this is my script
#!/bin/sh

if [ $# != 2 ]
then
echo "Usage: tsar-udp server_ip server_port"
else

tsar -i 10 --cpu --io --mem --udp --tcp --traffic --tcpx --load --pcsw -l | while read line
do
echo $line | nc -u -w 0 $1 $2
echo $line
done

fi

so per second i have spawn many many nc in that shell.
