jiaming2li opened a new pull request, #3551:
URL: https://github.com/apache/dubbo-go/pull/3551
Enhance OpenTelemetry tracing diagnostics (Fixes #3338, scope item 1).
- Standardized span names to `dubbo.consumer <service>/<method>` (client)
and `dubbo.provider <service>/<method>` (server).
- Enriched span attributes:
- OTel semantic conventions where available: `rpc.system=apache_dubbo`,
`rpc.service`, `rpc.method`, `server.address`, `server.port`.
- Dubbo-specific info under a stable `dubbo.*` namespace: `dubbo.side`,
`dubbo.protocol`, `dubbo.group`, `dubbo.version`.
- Extracted shared `buildSpanName` / `buildSpanAttributes` helpers to remove
the duplicated span-construction logic between the client and server filters.
- Added tests asserting span name, span kind, and attributes for both
filters using an in-memory span recorder.
