    Configure the chef server to push statistics in statsd format

cat >>/etc/opscode/chef-server.rb <<EOF
estatsd['protocol'] = 'statsd'
EOF
chef-server-ctl reconfigure

For demonstration purposes view the stats that are being pushed from the chef server
apt-get install socat
socat -u udp-recv:9466 -

Use statsd to aggregate and perform calculations on the stats on a 10 second interval

Download and unpack nodejs binary and statsd on the chef server
cd ~
wget https://nodejs.org/dist/v4.2.2/node-v4.2.2-linux-x64.tar.gz
tar xzf node-v4.2.2-linux-x64.tar.gz
wget https://github.com/etsy/statsd/archive/master.tar.gz
tar xzf master.tar.gz

Configure statsd
cat > localConfig.js <<EOF
{
  console: { prettyprint: true }
, port: 9466
, backends: [ "./backends/console" ]
}
EOF

Run statsd and parse out counter_rates (output will appear on a 10 second interval)
./node-v4.2.2-linux-x64/bin/node ./statsd-master/stats.js localConfig.js | perl -lane 'print localtime. $_ if /counter_rates:/ ... /sets:/'
