Grafana performance dashboard missing java CPU metrics

Open splett2 opened this issue 10 months ago • 1 comments

Hi, I was taking a look at the GRPC multi-language performance dashboard linked in https://grpc.io/docs/guides/benchmarking/, e.g. https://grafana-dot-grpc-testing.appspot.com/?orgId=1 and noticed that the CPU usage metrics for Java are missing. It would be interesting to know how java stacks up on that front.

The Java runner doesn't provide the CPU metrics. We'd need to set these fields: https://github.com/grpc/grpc-java/blob/922dc8a999531c91b0fa77386e0609745fae939f/benchmarks/src/main/proto/grpc/testing/stats.proto#L68

https://github.com/grpc/grpc-java/blob/922dc8a999531c91b0fa77386e0609745fae939f/benchmarks/src/main/proto/grpc/testing/stats.proto#L23

And get the data from like /proc or such.
