>
> In case of multiple RPC servers in the same JVM it's hard to identify the
> metric data. The only available information as of now is the port number.
> Server name is also added in the constructor of Server.java but it's not used
> at all.
> This patch fix this behaviour:
> 1. The server name is saved to a field in Server.java (constructor signature
> is not changed)
> 2. ServerName is added as a tag to the metrics in RpcMetrics
> 3. The naming convention for the severs are fix.
> About 3: if the server name is not defined the current code tries to identify
> the name from the class name. Which is not always an easy task as in some
> cases the server has a protobuf generated dirty name which also could be an
> inner class.
> The patch also improved the detection of the name (if it's not defined). It's
> a compatible change as the current name is not user ad all.
