Shuyan Zhang updated HDFS-16683:
--------------------------------
Environment: (was: When an RPC protocol is used, the metric of
protocol-related methods should be initialized; otherwise, metric information
will be incomplete. For example, when we call
HAServiceProtocol#monitorHealth(), only the metric of monitorHealth() are
initialized, and the metric of transitionToStandby() are still not reported.
This incompleteness caused a little trouble for our monitoring system.
The root cause is that the parameter passed by RpcEngine to
MutableRatesWithAggregation#init(java.lang.Class<?>) is always XXXProtocolPB,
which is inherited from BlockingInterface and does not implement any methods.
We should fix this bug.)
> All method metrics related to the rpc protocol should be initialized
