Hi, I have 2 clusters, Master (a) - Slave (b) replication. B doesn't have client write or reads, all handlers (100) are waiting but rpc.metrics.RpcQueueTime_num_ops and rpc.metrics.RpcQueueTime_avg_time reports to be rpc calls to be queued. There are some screenshots below to show ganglia metrics. How is this behaviour explained? I have looked for metrics specifications but can't find much information.
