Currently RPC metrics has the following information:
Context name *rpc* and record name *metrics* has the following:
||Type||Name of the metrics||Description||
|MetricsTimeVaryingLong|ReceivedBytes|Number of bytes in RPC requests received
in reporting
period|
|MetricsTimeVaryingLong|SentBytes|Number of bytes sent RPC response in
reporting period|
|MetricsTimeVaryingRate|RpcQueueTime|Time a request spent in queue and rate at
which RPC requests are received|
|rpcProcessingTime|RpcProcessingTime|Number of RPC request processed and time
for processing it|
|MetricsIntValue|NumOpenConnections|Number of open connections to the RPC
server|
|MetricsIntValue|callQueueLen|Length of the RPC queue|
|MetricsTimeVaryingInt |rpcAuthenticationFailures|Number of authentication
failures at the RPC layer|
|MetricsTimeVaryingInt |rpcAuthenticationSuccesses|Number of authentication
success at the RPC layer|
|MetricsTimeVaryingInt |rpcAuthorizationFailures|Number of authorization
failure at the RPC layer|
|MetricsTimeVaryingInt |rpcAuthorizationSuccesses|Number of authorization
success at the RPC layer|
Context name *rpc* and record name *detailed-metrics* has metrics for each RPC

> Currently RPC metrics tracks items that provides summary of RPC usage along
> with more detailed per method statistics that tracks number of method calls
> made, time spent on that call. Combining both summary and detailed together
> results in large metrics report which metrics collection systems may not
> handle. Proposal is to split the metrics into summary and detailed metrics.
