how zookeper talk with kafka to know kafka is up

how zookeper talk with kafka to know kafka is up

hi all

we have ambari cluster , version 2.6.x , with 3 kafka machine and 3 zookeper servers

while kafka machines are not chosted with zookeper server ( kafka are on different machines )

in order to get the brokers id , we do the following on the zookeper servers

cd /usr/hdp/current/zookeeper-server/bin

./zkCli.sh

ls /brokers/ids

results should be the three brokers id's as

1011  1012  1013

my question is - in which way zookeper know that broker is up?

or to be more specific

which cli zookeper execute in order to identify that kafka broker is up ?
