> Currently, the TracerDriver exposed the latency of ZK operations, in multi-tenant environment,
extra metrics are required to help tracing and monitoring:
> * the bytes being sent and received, so we can monitor the client usage scenarios.
> * which ensemble participant the client is talking to, used to find out the problematic
Zk server when the issue happened.
> * the z-node path, to easily find out which z-node caused the problem, like high load,
etc.
