stdoutmetric exporter observability #7492

mahendrabishnoi2 · 2025-10-11T17:39:51Z

This PR adds support for below self observability metrics for stdoutmetric exporter

otel.sdk.exporter.metric_data_point.inflight
otel.sdk.exporter.metric_data_point.exported
otel.sdk.exporter.operation.duration

These metrics are experimental and hence behind a feature flag OTEL_GO_X_OBSERVABILITY.
Definition of above metrics is available at https://github.com/open-telemetry/semantic-conventions/blob/v1.36.0/docs/otel/sdk-metrics.md

Observability Implementation Checklist

Based on the project Observability guidelines, ensure the following are completed:

Environment Variable Activation

Observability features are disabled by default
Features are activated through the OTEL_GO_X_OBSERVABILITY environment variable
Use consistent pattern with x.Observability.Enabled() check ¹
Follow established experimental feature pattern ²³

Encapsulation

Instrumentation is encapsulated within a dedicated struct (e.g., Instrumentation)
Instrumentation is not mixed into the instrumented component
Instrumentation code is in its own file or package if complex/reused
Instrumentation setup doesn't bloat the main component code

Initialization

Initialization is only done when observability is enabled
Setup is explicit and side-effect free
Return errors from initialization when appropriate
Use the global Meter provider (e.g., otel.GetMeterProvider())
Include proper meter configuration with:
- Instrumentation package name is used for the Meter
- Instrumentation version (e.g. Version)
- Schema URL (e.g. SchemaURL)

Performance

Little to no overhead when observability is disabled
Expensive operations are only executed when observability is enabled
When enabled, instrumentation code paths are optimized to reduce allocation/computation overhead

Attribute and Option Allocation Management

Use sync.Pool for attribute slices and options with dynamic attributes
Pool objects are properly reset before returning to pool
Pools are scoped for maximum efficiency while ensuring correctness

Caching

Static attribute sets known at compile time are pre-computed and cached
Common attribute combinations use lookup tables/maps

Benchmarking

Benchmarks provided for all instrumentation code
Benchmark scenarios include both enabled and disabled observability
Benchmark results show impact on allocs/op, B/op, and ns/op (use b.ReportAllocs() in benchmarks)

Error Handling and Robustness

Errors are reported back to caller when possible
Partial failures are handled gracefully
Use partially initialized components when available
Return errors to caller instead of only using otel.Handle()
Use otel.Handle() only when component cannot report error to user

Context Propagation

Observability measurements receive the context from the function being measured (don't break context propagation by using context.Background())

Semantic Conventions Compliance

All metrics follow OpenTelemetry Semantic Conventions
Use the otelconv convenience package for metric semantic conventions
Component names follow semantic conventions
Use package path scope type as stable identifier for non-standard components
Component names are stable unique identifiers
Use global counter for uniqueness if necessary
Component ID counter is resettable for deterministic testing

Testing

Use deterministic testing with isolated state
Restore previous state after tests (t.Cleanup())
Isolate meter provider for testing
Use t.Setenv() for environment variable testing
Reset component ID counter for deterministic component names
Test order doesn't affect results

…GO_X_SELF_OBSERVABILITY

…etrics 1. otel.sdk.exporter.metric_data_point.inflight 2. otel.sdk.exporter.metric_data_point.exported 3. otel.sdk.exporter.operation.duration

…exporter

… the user

- use pool to amortize slice allocation - pass actual context - use t.Cleanup instead of defer in tests - improve readability by returning without using err var

- use metricdatatest for comparision in testcase

…ng in tests
