In datadog, however, they -//! are less granular - it is expected in Datadog that a service will have single -//! primary span name that is the root of all traces within that service, with an additional piece of -//! metadata called resource_name providing granularity. See [here](https://docs.datadoghq.com/tracing/guide/configuring-primary-operation/) -//! -//! The Datadog Golang API takes the approach of using a `resource.name` OpenTelemetry attribute to set the -//! resource_name. See [here](https://github.com/DataDog/dd-trace-go/blob/ecb0b805ef25b00888a2fb62d465a5aa95e7301e/ddtrace/opentracer/tracer.go#L10) -//! -//! Unfortunately, this breaks compatibility with other OpenTelemetry exporters which expect -//! a more granular operation name - as per the OpenTracing specification. -//! -//! This exporter therefore takes a different approach of naming the span with the name of the -//! tracing provider, and using the span name to set the resource_name. This should in most cases -//! lead to the behaviour that users expect. -//! -//! Datadog additionally has a span_type string that alters the rendering of the spans in the web UI. -//! This can be set as the `span.type` OpenTelemetry span attribute. -//! -//! For standard values see [here](https://github.com/DataDog/dd-trace-go/blob/ecb0b805ef25b00888a2fb62d465a5aa95e7301e/ddtrace/ext/app_types.go#L31). -//! -//! If the default mapping is not fit for your use case, you may change some of them by providing [`FieldMappingFn`]s in pipeline. -//! -//! ## Performance -//! -//! For optimal performance, a batch exporter is recommended as the simple exporter will export -//! each span synchronously on drop. You can enable the [`rt-tokio`], [`rt-tokio-current-thread`] -//! or [`rt-async-std`] features and specify a runtime on the pipeline to have a batch exporter -//! configured for you automatically. -//! -//! ```toml -//! [dependencies] -//! opentelemetry = { version = "*", features = ["rt-tokio"] } -//! opentelemetry-datadog = "*" -//! ``` -//! -//! ```no_run -//! # fn main() -> Result<(), opentelemetry::trace::TraceError> { -//! let tracer = opentelemetry_datadog::new_pipeline() -//! .install_batch(opentelemetry_sdk::runtime::Tokio)?; -//! # Ok(()) -//! # } -//! ``` -//! -//! [`rt-tokio`]: https://tokio.rs -//! [`rt-tokio-current-thread`]: https://tokio.rs -//! [`rt-async-std`]: https://async.rs -//! -//! ## Bring your own http client -//! -//! Users can choose appropriate http clients to align with their runtime. -//! -//! Based on the feature enabled. The default http client will be different. If user doesn't specific -//! features or enabled `reqwest-blocking-client` feature. The blocking reqwest http client will be used as -//! default client. If `reqwest-client` feature is enabled. The async reqwest http client will be used. If -//! `surf-client` feature is enabled. The surf http client will be used. -//! -//! Note that async http clients may need specific runtime otherwise it will panic. User should make -//! sure the http client is running in appropriate runime. -//! -//! Users can always use their own http clients by implementing `HttpClient` trait. -//! -//! ## Kitchen Sink Full Configuration -//! -//! Example showing how to override all configuration options. See the -//! [`DatadogPipelineBuilder`] docs for details of each option. -//! -//!

Replace tracer_builder() with tracer_with_scope(InstrumentationScope) - Add TracerProvider trait import where needed - Replace with_config() with individual builder methods (with_sampler, with_span_limits, with_resource) PeriodicReader API: - Remove runtime parameter from builder() - Remove with_timeout() (no longer supported in standard processor) SpanExporter API: - Use SpanExporter::builder().with_tonic()/with_http() pattern - Wrap SpanExporter in Arc for 'static futures in apollo_otlp_exporter Prometheus: - Update dependency from 0.13 to 0.14 to match opentelemetry-prometheus Non-exhaustive types: - Add wildcard patterns for Value and Array enum matches - Add .. to KeyValue pattern matching Resource API: - Resource::get() now takes &Key instead of impl Into - Resource::merge() is now private - use builder with detectors instead Datadog: - Remove with_trace_config() call (config is set via individual methods) - Use to_resource() directly instead of Config conversion --- Cargo.lock | 27 +----- apollo-router/Cargo.toml | 2 +- apollo-router/src/metrics/aggregation.rs | 13 +-- apollo-router/src/metrics/filter.rs | 8 +- .../plugins/telemetry/apollo_otlp_exporter.rs | 19 ++-- apollo-router/src/plugins/telemetry/config.rs | 45 +++++----- .../telemetry/config_new/instruments.rs | 1 + .../src/plugins/telemetry/config_new/mod.rs | 3 +- .../plugins/telemetry/dynamic_attribute.rs | 4 +- .../src/plugins/telemetry/formatters/json.rs | 3 +- .../src/plugins/telemetry/formatters/mod.rs | 2 + .../src/plugins/telemetry/formatters/text.rs | 2 +- .../plugins/telemetry/metrics/apollo/mod.rs | 9 +- .../src/plugins/telemetry/metrics/otlp.rs | 4 +- apollo-router/src/plugins/telemetry/otlp.rs | 88 ++++++++++--------- .../plugins/telemetry/reload/activation.rs | 5 +- .../src/plugins/telemetry/reload/builder.rs | 2 +- .../src/plugins/telemetry/reload/otel.rs | 6 +- .../src/plugins/telemetry/reload/tracing.rs | 8 +- .../src/plugins/telemetry/resource.rs | 22 ++--- .../telemetry/tracing/apollo_telemetry.rs | 2 +- .../plugins/telemetry/tracing/datadog/mod.rs | 15 ++-- .../src/plugins/telemetry/tracing/mod.rs | 7 +- .../src/plugins/telemetry/tracing/otlp.rs | 6 +- 24 files changed, 145 insertions(+), 158 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 2b42574832..d17de92279 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -388,7 +388,7 @@ dependencies = [ "paste", "pin-project-lite", "pretty_assertions", -

prost upgraded to 0.14 to match opentelemetry-proto - MetricReader trait now requires temporality() and shutdown_with_timeout() - Removed TemporalitySelector and AggregationSelector traits (merged into MetricReader) - ResourceMetrics/ScopeMetrics/Metric fields are now private, use accessor methods - DataPoint replaced with GaugeDataPoint and SumDataPoint - Aggregation trait replaced with AggregatedMetrics/MetricData enums - PeriodicReader is now generic over the exporter type - InMemoryMetricsExporter renamed to InMemoryMetricExporter - PushMetricExporter::export() now returns impl Future Updates to the trace API: - TraceId::from_u128() -> TraceId::from() - SpanId::from_u64() -> SpanId::from() - SpanData::instrumentation_lib -> instrumentation_scope - SdkTracerProvider::tracer_builder() -> tracer_with_scope(InstrumentationScope) - TracerProviderBuilder::with_config() removed, use with_sampler() directly - Resource no longer implements Default, use Resource::builder_empty().build() - force_flush() now returns OTelSdkResult instead of Vec --- Cargo.lock | 52 +-- apollo-router/Cargo.toml | 4 +- apollo-router/src/metrics/aggregation.rs | 102 ++--- apollo-router/src/metrics/filter.rs | 65 ++- apollo-router/src/metrics/mod.rs | 375 ++++++++++++------ .../src/plugins/telemetry/config_new/mod.rs | 10 +- .../telemetry/config_new/router/attributes.rs | 4 +- .../telemetry/config_new/router/selectors.rs | 8 +- .../config_new/subgraph/selectors.rs | 4 +- .../config_new/supergraph/selectors.rs | 4 +- .../src/plugins/telemetry/error_handler.rs | 6 +- .../src/plugins/telemetry/fmt_layer.rs | 15 +- apollo-router/src/plugins/telemetry/mod.rs | 2 +- .../src/plugins/telemetry/otel/tracer.rs | 2 +- .../telemetry/tracing/apollo_telemetry.rs | 8 +- .../tracing/datadog/agent_sampling.rs | 20 +- .../telemetry/tracing/datadog/propagator.rs | 22 +- .../tracing/datadog/span_processor.rs | 8 +- apollo-router/src/tracer.rs | 14 +- apollo-router/tests/common.rs | 51 +-- .../tests/integration/telemetry/datadog.rs | 2 +- .../tests/integration/telemetry/otlp/mod.rs | 2 +- .../tests/telemetry_resource_tests.rs | 28 +- 23 files changed, 415 insertions(+), 393 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index d17de92279..3be9c1c642 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -389,8 +389,8 @@ dependencies = [ "pin-project-lite", "pretty_assertions", "prometheus", -

In OTel SDK 0.31, the standard BatchSpanProcessor uses a dedicated thread with futures::executor::block_on() which doesn't provide a Tokio runtime context. This causes "there is no reactor running" panics when the exporter tries to make HTTP calls. The fix uses the experimental async runtime variant of BatchSpanProcessor with runtime::Tokio, which properly executes the exporter's futures in the Tokio runtime. Note: Other exporters (OTLP, Zipkin, Datadog) work fine with the standard BatchSpanProcessor as they handle async internally. --- apollo-router/Cargo.toml | 3 ++- apollo-router/src/plugins/telemetry/tracing/apollo.rs | 5 +++-- 2 files changed, 5 insertions(+), 3 deletions(-) diff --git a/apollo-router/Cargo.toml b/apollo-router/Cargo.toml index 5c80633a77..8792d02f99 100644 --- a/apollo-router/Cargo.toml +++ b/apollo-router/Cargo.toml @@ -167,6 +167,7 @@ opentelemetry_sdk = { version = "0.31", default-features = false, features = [ "trace", "metrics", "spec_unstable_metrics_views", + "experimental_trace_batch_span_processor_with_async_runtime", ] } opentelemetry-aws = "0.19" opentelemetry-datadog = { version = "0.19", features = ["reqwest-client"] } @@ -320,7 +321,7 @@ num-traits = "0.2.19" once_cell.workspace = true opentelemetry-stdout = { version = "0.31", features = ["trace"] } opentelemetry = { version = "0.31", features = ["testing"] } -opentelemetry_sdk = { version = "0.31", features = ["testing"] } +opentelemetry_sdk = { version = "0.31", features = ["testing", "experimental_trace_batch_span_processor_with_async_runtime"] } opentelemetry-proto = { version = "0.31", features = [ "metrics", "trace", diff --git a/apollo-router/src/plugins/telemetry/tracing/apollo.rs b/apollo-router/src/plugins/telemetry/tracing/apollo.rs index 95b12e9940..74c0889ff1 100644 --- a/apollo-router/src/plugins/telemetry/tracing/apollo.rs +++ b/apollo-router/src/plugins/telemetry/tracing/apollo.rs @@ -1,5 +1,6 @@ //!

This caused test failures in integration tests that assert no error logs. The fix: - Track which meter provider types have readers in MetricsBuilder - Only return providers with readers from build() to prevent SDK errors - Always set a noop Public provider when metrics config changes (even without exporters) to ensure old providers are replaced on hot reload - Use noop providers as defaults in AggregateMeterProvider instead of SDK providers without readers - Filter observable instruments early in FilterMeterProvider to avoid registering callbacks with providers that would reject them Also cleans up unused code: - Remove unused Dynamic variant from MeterProviderInner - Remove unused public_dynamic function - Simplify ObservableCallbackRegistry (single callback per instrument) --- apollo-router/src/metrics/aggregation.rs | 54 ++++++------------- apollo-router/src/metrics/filter.rs | 46 +++++++++------- .../src/plugins/telemetry/reload/builder.rs | 24 ++++++--- .../src/plugins/telemetry/reload/metrics.rs | 11 ++++ 4 files changed, 71 insertions(+), 64 deletions(-) diff --git a/apollo-router/src/metrics/aggregation.rs b/apollo-router/src/metrics/aggregation.rs index 3a041f0908..e37f936a25 100644 --- a/apollo-router/src/metrics/aggregation.rs +++ b/apollo-router/src/metrics/aggregation.rs @@ -3,7 +3,6 @@ use std::collections::HashMap; use std::collections::HashSet; use std::mem; use std::sync::Arc; -use std::sync::atomic::AtomicU64; use derive_more::From; use opentelemetry::InstrumentationScope; @@ -23,7 +22,6 @@ use opentelemetry::metrics::ObservableGauge; use opentelemetry::metrics::ObservableUpDownCounter; use opentelemetry::metrics::SyncInstrument; use opentelemetry::metrics::UpDownCounter; -use opentelemetry_sdk::metrics::SdkMeterProvider; use parking_lot::Mutex; use strum::Display; use strum::EnumCount; @@ -61,19 +59,11 @@ pub(crate) struct AggregateMeterProvider { impl Default for AggregateMeterProvider { fn default() -> Self { - let meter_provider = AggregateMeterProvider { + // All providers start as noop to avoid OTel SDK errors. + // Real providers are set via set() during configuration. + AggregateMeterProvider { inner: Arc::new(Mutex::new(Some(Inner::default()))), - }; - - // If the regular global meter provider has been set then the aggregate meter provider will use it.

Sync gauges are simpler and the task can record values directly. --- apollo-router/src/cache/metrics.rs | 563 +++++------------- apollo-router/src/cache/redis.rs | 21 +- apollo-router/src/cache/storage.rs | 9 +- apollo-router/src/plugins/cache/entity.rs | 20 +- apollo-router/src/plugins/cache/tests.rs | 30 +- .../src/plugins/response_cache/plugin.rs | 18 +- .../plugins/response_cache/storage/redis.rs | 5 + 7 files changed, 224 insertions(+), 442 deletions(-) diff --git a/apollo-router/src/cache/metrics.rs b/apollo-router/src/cache/metrics.rs index 328a046aec..abcc4412fd 100644 --- a/apollo-router/src/cache/metrics.rs +++ b/apollo-router/src/cache/metrics.rs @@ -1,56 +1,32 @@ use std::sync::Arc;

In datadog, however, they +//! are less granular - it is expected in Datadog that a service will have single +//! primary span name that is the root of all traces within that service, with an additional piece of +//! metadata called resource_name providing granularity. See [here](https://docs.datadoghq.com/tracing/guide/configuring-primary-operation/) +//! +//! The Datadog Golang API takes the approach of using a `resource.name` OpenTelemetry attribute to set the +//! resource_name. See [here](https://github.com/DataDog/dd-trace-go/blob/ecb0b805ef25b00888a2fb62d465a5aa95e7301e/ddtrace/opentracer/tracer.go#L10) +//! +//! Unfortunately, this breaks compatibility with other OpenTelemetry exporters which expect +//! a more granular operation name - as per the OpenTracing specification. +//! +//! This exporter therefore takes a different approach of naming the span with the name of the +//! tracing provider, and using the span name to set the resource_name. This should in most cases +//! lead to the behaviour that users expect. +//! +//! Datadog additionally has a span_type string that alters the rendering of the spans in the web UI. +//! This can be set as the `span.type` OpenTelemetry span attribute. +//! +//! For standard values see [here](https://github.com/DataDog/dd-trace-go/blob/ecb0b805ef25b00888a2fb62d465a5aa95e7301e/ddtrace/ext/app_types.go#L31). +//! +//! If the default mapping is not fit for your use case, you may change some of them by providing [`FieldMappingFn`]s in pipeline. +//! +//! ## Performance +//! +//! For optimal performance, a batch exporter is recommended as the simple exporter will export +//! each span synchronously on drop. You can enable the [`rt-tokio`], [`rt-tokio-current-thread`] +//! or [`rt-async-std`] features and specify a runtime on the pipeline to have a batch exporter +//! configured for you automatically. +//! +//! ```toml +//! [dependencies] +//! opentelemetry = { version = "*", features = ["rt-tokio"] } +//! opentelemetry-datadog = "*" +//! ``` +//! +//! ```no_run +//! # fn main() -> Result<(), opentelemetry::trace::TraceError> { +//! let tracer = opentelemetry_datadog::new_pipeline() +//! .install_batch(opentelemetry_sdk::runtime::Tokio)?; +//! # Ok(()) +//! # } +//! ``` +//! +//! [`rt-tokio`]: https://tokio.rs +//! [`rt-tokio-current-thread`]: https://tokio.rs +//! [`rt-async-std`]: https://async.rs +//! +//! ## Bring your own http client +//! +//! Users can choose appropriate http clients to align with their runtime. +//! +//! Based on the feature enabled. The default http client will be different. If user doesn't specific +//! features or enabled `reqwest-blocking-client` feature. The blocking reqwest http client will be used as +//! default client. If `reqwest-client` feature is enabled. The async reqwest http client will be used. If +//! `surf-client` feature is enabled. The surf http client will be used. +//! +//! Note that async http clients may need specific runtime otherwise it will panic. User should make +//! sure the http client is running in appropriate runime. +//! +//! Users can always use their own http clients by implementing `HttpClient` trait. +//! +//! ## Kitchen Sink Full Configuration +//! +//! Example showing how to override all configuration options.
