Report gRPC status code in client-computed stats by bric3 · Pull Request #10805 · DataDog/dd-trace-java

bric3 · 2026-03-11T13:29:55Z

What Does This Do

Reports the gRPC status code via Client Computed Stats.

This status is supported since 7.65.0 in the agent (DataDog/datadog-agent#34220), which is the minimal version needed to support CCS as well.

Current grpc instrumentations capture the status code, but not its numeric value, so it was chosen to add a new span tag that will be used in the client aggregation.

    span.setTag("status.code", status.getCode().name());
    span.setTag("grpc.status.code", status.getCode().name());
+   span.setTag("rpc.grpc.status_code", status.getCode().value());

This affects grpc and armeria instrumentations.

Motivation

Completeness of CCS.

Additional notes

When client-computed stats (CCS) are enabled, the agent merges stats it computes itself from raw spans with stats pre-computed by the tracer.

For gRPC spans, without Client Computed Stats (metrics) the agent resolves the status code from the span's tags via getGRPCStatusCode(), which always returns a numeric string (e.g. 4) or an empty string. With CCS enabled, the code uses GRPCStatusCode without translation.

flowchart TB
      subgraph tracer["dd-trace-java"]
          span["gRPC span<br>grpc.status.code = 'DEADLINE_EXCEEDED'<br>rpc.grpc.status_code = 4"]

          span -->|raw spans| v04["POST /v0.4/traces<br>msgpack"]
          span --> agg["ConflatingMetricsAggregator<br>reads rpc.grpc.status_code<br>GRPCStatusCode = '4'"]
          agg -->|pre-computed stats| v06["POST /v0.6/stats<br>msgpack · GRPCStatusCode: '4'"]
      end

      subgraph agent["datadog-agent"]
          v04 --> agentPath["NewAggregationFromSpan<br>getGRPCStatusCode<br>meta[grpc.status.code]='DEADLINE_EXCEEDED' → '4'"]
          v06 --> ccsPath["NewAggregationFromGroup<br>GRPCStatusCode → '4'"]

          agentPath --> k1["key{GRPCStatusCode:'4',...}"]
          ccsPath   --> k2["key{GRPCStatusCode:'4',...}"]
      end

This change mimics the aggregation of the agent, and what is expected from the agent, in NewAggregationFromGroup.

Protocol wise ClientGroupedStats.GRPC_status_code is a string.

      CharSequence httpMethod,
-      CharSequence httpEndpoint) {
+      CharSequence httpEndpoint,
+      CharSequence grpcStatusCode) {


The implmenetation does not look correct. AFAIK our integrations are putting a named enum on grpc.status.code

span.setTag("status.code", status.getCode().name());

On the other side here it's required put a numeric value. The agent is doing a translation (see aggregate.go):

var grpcStatusMap = map[string]string{ "CANCELLED": "1", "CANCELED": "1", "INVALIDARGUMENT": "3", "DEADLINEEXCEEDED": "4", "NOTFOUND": "5", "ALREADYEXISTS": "6", "PERMISSIONDENIED": "7", "RESOURCEEXHAUSTED": "8", "FAILEDPRECONDITION": "9", "OUTOFRANGE": "11", "DATALOSS": "15", }

We already have those numbers. I can suggest to enrich first the in place integrations by feeding the status code under the otel tag rpc.grpc.status_code and then source the fields for the stats from this tag instead.

Please also double check that the proto accept a string and not an integer

# Conflicts: # dd-trace-core/src/main/java/datadog/trace/common/metrics/MetricKey.java

When client-computed stats (CCS) are enabled, the agent **merges** stats it computes itself from raw spans with stats pre-computed by the tracer. For gRPC spans, without Client Computed Stats (metrics) the agent resolves the status code from the span's tags via [`getGRPCStatusCode()`](https://github.com/DataDog/datadog-agent/blob/47938ea8c9b9894dcb03dc3f81cf2c6e408f1b6c/pkg/trace/stats/aggregation.go#L167-L221), which always returns a numeric string (e.g. `4`) or an empty string. With CCS enabled, the code uses [`GRPCStatusCode`](https://github.com/DataDog/datadog-agent/blob/47938ea8c9b9894dcb03dc3f81cf2c6e408f1b6c/pkg/trace/stats/aggregation.go#L160) without translation. This change mimics the aggregation of the agent, and what is expected from the agent, in [`NewAggregationFromGroup`](https://github.com/DataDog/datadog-agent/blob/47938ea8c9b9894dcb03dc3f81cf2c6e408f1b6c/pkg/trace/stats/aggregation.go#L146-L165). Protocol wise [ClientGroupedStats.GRPC_status_code](https://github.com/DataDog/datadog-agent/blob/47938ea8c9b9894dcb03dc3f81cf2c6e408f1b6c/pkg/proto/datadog/trace/stats.proto#L103) is a `string`.
