InternalNettyServerBuilder -> what is setStatsEnabled?

[ivan.to...@gmail.com]

Hello gRPC team, we were checking out the NettyServerBuilder and we stumbled upon InternalNettyServerBuilder, which has a quite interesting comment.

/**

 * Internal {@link InternalNettyServerBuilder} accessor.  This is intended for usage internal to

 * the gRPC team.  If you *really* think you need to use this, contact the gRPC team first.

 */

Could you please shed some light on what are the statistics and metrics being recorded here?

Do they record when a message is incoming and when is outgoing the server, and how can we see these data?

The stats are reported to OpenCensus. Once you load your application with the proper OpenCensus runtime libraries, they will report the metrics to a backend such as StackDriver.

About how to see the data, please refer to https://opencensus.io/guides/grpc/java/

In particular, here is the full list of metrics being recorded: https://www.javadoc.io/doc/io.opencensus/opencensus-contrib-grpc-metrics/0.23.0
