Wrong metric name zookeeper_PacketsSent/zookeeper_PacketsReceived

[Yura Ivanovskiy]

Hello!

I've faced with strange issue, name of those two metrics (zookeeper_PacketsSent/zookeeper_PacketsReceived) contain "MetricName + Value", for e.g.: zookeeper_PacketsReceived:_16625546 , should be zookeeper_PacketsReceived.

# HELP zookeeper_PacketsReceived:_16625546 PacketsReceived (org.apache.ZooKeeperService<name0=ReplicatedServer_id1, name1=replica.1, name2=Follower><>PacketsReceived)
# TYPE zookeeper_PacketsReceived:_16625546 counter
zookeeper_PacketsReceived:_16625546{memberType="Follower",replicaId="1",} 1.6625546E7

# HELP zookeeper_PacketsSent:_17183580 PacketsSent (org.apache.ZooKeeperService<name0=ReplicatedServer_id1, name1=replica.1, name2=Follower><>PacketsSent)
# TYPE zookeeper_PacketsSent:_17183580 counter
zookeeper_PacketsSent:_17183580{memberType="Follower",replicaId="1",} 1.718358E7

What am I doing wrong ?
Thank You!
