Description

on fresh installed Zookeeper 3.6.1 (without workload)

I run the following command:

wget -q -O- http://127.0.0.1:7000/metrics | grep -i packets_

# HELP packets_received packets_received
# TYPE packets_received gauge
packets_received 8004.0
# HELP packets_sent packets_sent
# TYPE packets_sent gauge
packets_sent 8009.0

looks like `packets_sent` and `packets_recived` have wrong metric type
cause 

sleep 5
wget -q -O- http://127.0.0.1:7000/metrics | grep -i packets_

returns

# HELP packets_received packets_received
# TYPE packets_received gauge
packets_received 8114.0
# HELP packets_sent packets_sent
# TYPE packets_sent gauge
packets_sent 8119.0
