ActiveControllerCount is always will be either 0 or 1 in 3 nodes kafka cluster?

Hi,

there is one Mbean in jconsole with name
"kafka.controller":type="KafkaController",name="ActiveControllerCount",

the Value of this Mbean is always 1 on one broker and 0 on all others
remaining broker of the 3 nodes kafka cluster.Will it always be like this?

As per my understanding it will always be 1 on one and only one broker as
there will be only one active controller in the cluster at any point of
time.

So it should be "kafka.controller":type="KafkaController",name="
*ActiveController*" and it sholud be a boolean value.

Please correct if I am wrong.
