MINOR: Expose ReplicaManager gauges
There are several gauges in core that are registered but cannot be accessed
programmatically. For example, gauges "LeaderCount", "PartitionCount",
"UnderReplicatedParittions" are all registered in ReplicaManager.scala but
there is no way to access them programmatically if one has access to the
kafka.server object. Other metrics, such as isrExpandRate (also in
ReplicaManager.scala) can be accessed. The solution here is trivial, add a var
<variable name> in front of newGauge, as shown below
val partitionCount newGauge(
"PartitionCount",
new Gauge[Int] {
def value = allPartitions.size
}
)
