Clean up span operations

[Lms24]

Description

Currently, many of our instrumentations send span ops that are not defined in conventions. This has two reasons:

1. The span op is simply still missing in conventions and needs to be added
2. SDKs sent suboptimal, maybe, too fragmented ops. For example, ops that include the framework or library name (e.g. middleware.express or function.sveltekit). Ops should be a bit more general than that.

I (okay, mostly my clanker, followed by a manual review) audited our instrumentations and these are the places we should make changes to:

Add to conventions

Effort	Priority	Category	Current op(s)	Replacement or conventions action	Registry status	Rationale / other findings	Preserve detail in	Production locations
XS	High	Routing	router	Add generic router to conventions	Missing	This is the common framework-neutral replacement target for frontend and backend router spans. Router work is distinct from both navigation roots and generic middleware.	ui.framework; navigation.phase; code.namespace or framework; router.name; route attributes	packages/angular/src/tracing.ts packages/sveltekit/src/client/svelte4BrowserTracing.ts packages/sveltekit/src/client/svelte5BrowserTracing.ts packages/ember/addon/utils/instrumentEmberAppInstanceForPerformance.ts packages/core/src/integrations/express/patch-layer.ts packages/server-utils/src/integrations/tracing-channel/express/instrumentation.ts packages/node/src/integrations/tracing/koa/vendored/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/koa.ts packages/node/src/integrations/tracing/hapi/vendored/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/hapi-utils.ts
XS	High	UI	ui.interaction.click|hover|drag|press	Keep ui.interaction.* and add all four leaves to conventions	Missing	Event Timing and INP interaction spans remain distinct from ui.action roots. Register click, hover, drag, and press as the finite interaction taxonomy.	Keep DOM event type and INP metric identity as attributes	packages/browser-utils/src/metrics/browserMetrics.ts packages/browser-utils/src/metrics/inp.ts packages/browser-utils/src/metrics/webVitalSpans.ts packages/browser/src/tracing/browserTracingIntegration.ts
XS	High	UI	ui.long-task / ui.long-animation-frame	Keep both operations and add them to conventions	Missing; ui.task is not equivalent	Long Task and Long Animation Frame are distinct browser performance APIs. The generic ui.task operation is not a semantic replacement.	browser.performance.entry_type=long-task|long-animation-frame	packages/browser-utils/src/metrics/browserMetrics.ts
XS	Medium	Browser	browser.${timingPhase}	Keep the browser timing-phase ops and add them to conventions	Only browser is currently registered	Current finite values include browser.unloadEvent, redirect, domContentLoadedEvent, loadEvent, connect, TLS/SSL, cache, DNS, request, and response. These phases remain useful as distinct operations.	Keep browser.performance.phase as complementary detail	packages/browser-utils/src/metrics/browserMetrics.ts
XS	Medium	Browser	measure	Keep measure and add it to conventions	Missing	PerformanceMeasure is a distinct, fixed, useful category.	Keep the PerformanceEntry name in the span name	packages/browser-utils/src/metrics/browserMetrics.ts
XS	Medium	Browser	resource.${initiatorType}	Keep initiator-type leaves, add them to conventions, and retain resource.other as fallback	Partially registered	Register the browser-standard initiator types, including currently undocumented values such as worker, icon, frame, object, ping, or track. Values outside the recognized browser set must still map to resource.other.	resource.initiator_type	packages/browser-utils/src/metrics/browserMetrics.ts
XS	Medium	HTTP	navigation.redirect	Keep navigation.redirect and add it to conventions	Missing	Redirect timing is a stable navigation category worth retaining as its own operation.	navigation.type=redirect	packages/browser/src/tracing/browserTracingIntegration.ts
XS	Medium	Storage	object.get|head|put|delete|list|upload_part|multipart_upload.abort|create|complete	Keep object.* and add an object-storage category to conventions	Missing	Unlike framework suffixes, these are a finite, provider-neutral API taxonomy for a domain not represented by current conventions. If a smaller taxonomy is preferred, normalize to object.read/write/delete before registration.	cloud provider and bucket/object identity remain attributes	packages/cloudflare/src/instrumentations/worker/instrumentR2.ts
XS	Medium	UI	ui.mount / ui.update / ui.unmount	Add ui.mount, ui.update, and ui.unmount to conventions; ui.render already exists	Generic lifecycle leaves are incomplete	These are framework-neutral replacement targets for equivalent React, Vue, and Svelte lifecycle work.	ui.framework; ui.component_name; ui.lifecycle_phase	packages/react/src/profiler.tsx packages/vue/src/tracing.ts packages/svelte/src/performance.ts
XS	Medium	UI	ui.webvital.lcp / ui.webvital.cls	Keep and add both to conventions	Missing	These are fixed, cross-framework browser concepts. They are better convention candidates than framework-specific lifecycle leaves.	web_vital.name and measurement value remain authoritative	packages/browser-utils/src/metrics/lcp.ts packages/browser-utils/src/metrics/cls.ts packages/browser-utils/src/metrics/webVitalSpans.ts
XL	High	Gen AI	gen_ai.embeddings / gen_ai.generate_content / gen_ai.rerank	embeddings / generate_content / rerank	Missing	These are fixed, provider-neutral, semantically distinct model operations. Add their unprefixed forms to conventions, then migrate SDK emission consistently.	gen_ai.operation.name and gen_ai.operation.type	packages/core/src/tracing/langchain/embeddings.ts packages/core/src/tracing/openai/index.ts packages/core/src/tracing/google-genai/index.ts packages/core/src/tracing/workers-ai/index.ts packages/core/src/tracing/vercel-ai/index.ts packages/server-utils/src/integrations/tracing-channel/openai.ts packages/server-utils/src/integrations/tracing-channel/google-genai.ts packages/server-utils/src/vercel-ai/vercel-ai-dc-subscriber.ts

Replace with another op

Note: The additive "gap" rows — adding a sentry.op to spans that currently emit none, which is not breaking — were split out into #23138 (rate-limit, DO WebSocket, DataLoader prime/clear/clearAll, GraphQL, generic-pool, Effect). The row numbering below therefore skips 21–23.

Row #	Effort	Priority	Category	Current op(s)	Replacement or conventions action	Registry status	Rationale / other findings	Preserve detail in	Production locations
1	S	High	FaaS	http.request (Firebase Functions)	function.gcp	http.request missing	The wrapper instruments all Firebase function trigger types, not only HTTP. A fixed http.request op is semantically wrong.	faas.trigger already exists; keep faas.provider=firebase	packages/node/src/integrations/tracing/firebase/otel/patches/functions.ts
2	S	High	HTTP	http.client.${serviceIdentifier}	http.client	Dynamic suffix missing	Service identity belongs in attributes; endpoint-derived suffixes fragment grouping and can be high-cardinality.	rpc.service or server.address / cloud.service.name	packages/google-cloud-serverless/src/integrations/google-cloud-http.ts
3	S	High	HTTP	http.client.prefetch / http.server.prefetch	http.client / http.server	Missing; base ops exist	OTel inference fabricates unregistered suffixes. Preserve direction and move prefetch to data.	sentry.http.prefetch=true	packages/opentelemetry/src/utils/parseSpanDescription.ts
4	S	High	Messaging	faas.queue plus sentry.op=queue.process on one span	queue.process only	queue.process exact; faas.queue missing	Cloudflare passes conflicting values. The sentry.op attribute wins, so faas.queue is effectively dead and should be removed.	—	packages/cloudflare/src/instrumentations/worker/instrumentQueue.ts
5	S	High	RPC	grpc.${serviceIdentifier}	grpc	Dynamic suffix missing	Service identity can be high-cardinality and already has standard RPC attributes.	rpc.service; rpc.method	packages/google-cloud-serverless/src/integrations/google-cloud-grpc.ts
6	S	High	UI	ui.angular.init / ui.angular.${methodKey}	ui.mount for init; function for TraceMethod	Parent ui.angular exists	The method-key suffix is user-controlled and unbounded. Component initialization is a mount; arbitrary decorated methods are functions.	ui.framework=angular; code.function.name	packages/angular/src/tracing.ts
7	S	High	UI	ui.ember.route.before_model|model|after_model|setup_controller	function	Missing	These are route-hook functions. The hook name is already available and should not be encoded in sentry.op.	code.function.name; ember.route.hook	packages/ember/addon/index.ts
8	S	High	UI	ui.ember.runloop.${queue}	ui.task	Missing; ui.task exists	Queue values are phase details and Ember can be configured with custom queues.	ui.framework=ember; ember.runloop.queue	packages/ember/addon/utils/instrumentEmberGlobals.ts
9	S	Medium	Browser	paint	browser.paint	browser.paint exists	Rename the raw paint operation to the registered browser-specific operation.	Keep the PerformanceEntry name in the span name	packages/browser-utils/src/metrics/browserMetrics.ts
10	S	Medium	FaaS	function.aws.lambda	function.aws	function.aws exists	Lambda is already implied by provider/runtime attributes; use the registered provider-level operation.	faas.name; cloud.provider=aws; cloud.platform=aws_lambda	packages/aws-serverless/src/requestSpanOptions.ts
11	S	Medium	HTTP	http.client.stream	http.client	Missing; parent exists	Streaming changes response behavior but not the HTTP operation category.	http.response.body.streaming=true	packages/browser/src/integrations/fetchStreamPerformance.ts
12	S	Medium	UI	ui.ember.component.render / component.definition / init	ui.render / function / ui.mount	Only parent ui.ember exists	Map render and initialization to cross-framework lifecycle ops. Component definition lookup is generic function work.	ui.framework=ember; ui.component_name; code.function.name	packages/ember/addon/utils/instrumentEmberGlobals.ts
13	M	High	Cache	cache.has_item|get_item|get_item_raw|get_items|get_keys|set_item|set_item_raw|set_items|remove_item|clear	cache.get / cache.put / cache.remove	Only target ops exist	This is the exact over-granularity the cache conventions avoid. Map has/get/list to get; set variants to put; remove/clear to remove.	db.operation.name already preserves the unstorage method	packages/nuxt/src/runtime/utils/instrumentStorage.ts packages/nitro/src/runtime/hooks/captureStorageEvents.ts
14	M	High	Database	db.redis / db.redis.connect	db.query for commands; db for connect	Missing; db and db.query exist	The datastore belongs in db.system.name. Library/system-specific op leaves are redundant.	db.system.name=redis; db.operation.name	packages/server-utils/src/redis/redis-dc-subscriber.ts packages/server-utils/src/integrations/tracing-channel/redis.ts
15	M	High	FaaS	faas.cron / faas.email / function.step.do	function	Missing	Cloudflare trigger/workflow phase belongs in attributes. Do not add a new op per trigger.	faas.trigger=timer|email; code.function.name; workflow.step.name	packages/cloudflare/src/instrumentations/worker/instrumentScheduled.ts packages/cloudflare/src/instrumentations/worker/instrumentEmail.ts packages/cloudflare/src/workflows.ts
16	M	High	FaaS	faas.trigger.toString() inferred as op	Infer function.<provider>, http.server, or queue.process from semantic evidence	Arbitrary values	OTel inference currently promotes an attribute value directly into sentry.op. Custom trigger strings can create unbounded ops.	Retain faas.trigger as data; never use it verbatim as op	packages/opentelemetry/src/utils/parseSpanDescription.ts
17	M	High	Gen AI	rpc on AWS Bedrock inference spans	chat or generate_content	rpc exists but is semantically wrong here	Bedrock adds GenAI attributes but inherits the generic AWS SDK rpc op. Select the GenAI operation from the Bedrock request type.	—	packages/server-utils/src/integrations/tracing-channel/aws-sdk/index.ts packages/server-utils/src/integrations/tracing-channel/aws-sdk/services/bedrock-runtime.ts
18	M	High	Middleware	app_creation.nestjs / request_context.nestjs / event.nestjs / plugin.hapi	function	Missing	These represent executable functions or setup work. Keep lifecycle/event/plugin identity in attributes.	code.function.name; nestjs.type; hapi.type; event.name	packages/nestjs/src/integrations/wrap-route.ts packages/nestjs/src/integrations/helpers.ts packages/node/src/integrations/tracing/hapi/vendored/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/hapi-utils.ts
19	M	High	RPC	rpc.server / mcp.server / mcp.notification.client_to_server|server_to_client	rpc	Only rpc exists	MCP is JSON-RPC and tRPC is RPC. Direction, method, notification kind, and protocol belong in attributes rather than op suffixes.	rpc.system=mcp|trpc; rpc.method; jsonrpc.*; messaging direction	packages/core/src/trpc.ts packages/core/src/integrations/mcp-server/spans.ts packages/core/src/integrations/mcp-server/attributes.ts
20	M	Medium	FaaS	function.gcp.http / event / cloud_event	function.gcp	function.gcp exists	Trigger type belongs in faas.trigger. The existing suffixes split one provider category.	faas.trigger	packages/google-cloud-serverless/src/gcpfunction/http.ts packages/google-cloud-serverless/src/gcpfunction/events.ts packages/google-cloud-serverless/src/gcpfunction/cloud_events.ts
24	L	High	Gen AI	gen_ai.create_agent / gen_ai.models / gen_ai.unknown / ai.run	function for create/models/unknown fallback; map ai.run to a known AI op when evidence exists	Missing	Agent compilation and model metadata calls are not inference operations. Unknown strings should not become conventions. Vercel AI's fallback should use an explicit mapping or a generic function op.	gen_ai.operation.name; code.function.name; retain provider SDK method	packages/core/src/tracing/langgraph/index.ts packages/core/src/tracing/anthropic-ai/index.ts packages/core/src/tracing/openai/index.ts packages/core/src/tracing/vercel-ai/index.ts
25	L	High	Messaging	message / message.produce / message.consume	queue.publish / queue.receive / queue.process	message* missing; queue.* exists	Kafka, AMQP, and Deno use a parallel non-convention taxonomy. Use messaging.operation.type to distinguish publish, receive, and process. Deno must not infer all ops from SpanKind alone.	messaging.system; messaging.operation.type	packages/server-utils/src/integrations/tracing-channel/kafkajs/spans.ts packages/server-utils/src/integrations/tracing-channel/amqplib.ts packages/opentelemetry/src/utils/parseSpanDescription.ts packages/deno/src/opentelemetry/tracer.ts
26	L	High	Middleware	request_handler.<library> / handler.nestjs / hono.request	function; use http.server only for a true inbound/internal HTTP boundary	Missing	Terminal framework handlers are functions, not new op categories. Hono app.request() is an in-process HTTP dispatch and should use http.server with HTTP attributes.	code.function.name; framework handler type; HTTP attributes for Hono dispatch	packages/core/src/integrations/express/patch-layer.ts packages/server-utils/src/integrations/tracing-channel/express/instrumentation.ts packages/node/src/integrations/tracing/connect/vendored/instrumentation.ts packages/node/src/integrations/tracing/hono/index.ts packages/node/src/integrations/tracing/fastify/v3/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/fastify/instrumentation.ts packages/elysia/src/withElysia.ts packages/nestjs/src/integrations/wrap-route.ts packages/hono/src/shared/patchAppRequest.ts
27	L	High	Middleware	router.express / router.koa / router.hapi	router (conventions addition tracked in the first table)	router is currently missing	Backend router layers should share one framework-neutral operation. They are semantically distinct from generic middleware.	code.namespace or framework; router.name; route attributes	packages/core/src/integrations/express/patch-layer.ts packages/server-utils/src/integrations/tracing-channel/express/instrumentation.ts packages/node/src/integrations/tracing/koa/vendored/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/koa.ts packages/node/src/integrations/tracing/hapi/vendored/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/hapi-utils.ts
28	L	Medium	UI	ui.angular.routing / ui.sveltekit.routing / ui.ember.transition	router (conventions addition tracked in the first table)	router must be added to conventions	All three measure router execution. Collapse framework identity while keeping router work distinct from the broader navigation root.	ui.framework; navigation.phase	packages/angular/src/tracing.ts packages/sveltekit/src/client/svelte4BrowserTracing.ts packages/sveltekit/src/client/svelte5BrowserTracing.ts packages/ember/addon/utils/instrumentEmberAppInstanceForPerformance.ts
29	L	Medium	UI	ui.react.* / ui.vue.* / ui.svelte.* lifecycle ops	ui.mount / ui.render / ui.update / ui.unmount (missing generic leaves tracked in the first table)	React leaves exist; generic leaves are incomplete	Preferred cleanup: normalize equivalent lifecycle work across frameworks. Current values include React mount/render/update; Vue render/activate/create/unmount/destroy/mount/update; Svelte init/update. Keeping React-specific leaves while collapsing other frameworks would preserve an arbitrary asymmetry.	ui.framework; ui.component_name; ui.lifecycle_phase	packages/react/src/profiler.tsx packages/vue/src/tracing.ts packages/svelte/src/performance.ts
30	XL	High	Framework functions	function.<framework>(.<phase>) and loader.remix / action.remix	function	function exists; function.nextjs/remix are legacy leaves	Collapse all framework and phase suffixes. This also resolves Remix's three competing loader/action taxonomies. Includes Next.js, Remix, React Router client/server, SvelteKit client/server, SolidStart, TanStack Start, and Cloudflare workflow steps.	code.function.name; code.namespace; framework-specific phase/type attributes	packages/nextjs/src/common/utils/tracingUtils.ts packages/nextjs/src/common/withServerActionInstrumentation.ts packages/remix/src/server/instrumentServer.ts packages/remix/src/server/integrations/tracing-channel.ts packages/remix/src/server/integrations/opentelemetry.ts packages/react-router/src/server/createServerInstrumentation.ts packages/react-router/src/server/wrapServerLoader.ts packages/react-router/src/server/wrapServerAction.ts packages/react-router/src/server/instrumentation/reactRouter.ts packages/react-router/src/server/instrumentation/util.ts packages/react-router/src/client/createClientInstrumentation.ts packages/react-router/src/client/hydratedRouter.ts packages/sveltekit/src/client/load.ts packages/sveltekit/src/server-common/load.ts packages/sveltekit/src/server-common/serverRoute.ts packages/sveltekit/src/server-common/integrations/svelteKitSpans.ts packages/solidstart/src/server/withServerActionInstrumentation.ts packages/tanstackstart-react/src/server/wrapFetchWithSentry.ts packages/cloudflare/src/workflows.ts
31	XL	High	Gen AI	gen_ai.chat / gen_ai.execute_tool / gen_ai.invoke_agent	chat / execute_tool / invoke_agent	Registry values are unprefixed	The SDK and source-of-truth registry disagree. Migrate to the exact convention values, or explicitly change the registry—but do not leave both. Before migration, replace SDK internals which identify AI spans via op.startsWith('gen_ai.') with gen_ai.operation.type/name.	gen_ai.operation.name and gen_ai.operation.type	packages/core/src/tracing/langchain/index.ts packages/core/src/tracing/langgraph/index.ts packages/core/src/tracing/langgraph/utils.ts packages/core/src/tracing/openai/index.ts packages/core/src/tracing/anthropic-ai/index.ts packages/core/src/tracing/google-genai/index.ts packages/core/src/tracing/workers-ai/index.ts packages/core/src/tracing/vercel-ai/index.ts packages/server-utils/src/integrations/tracing-channel/openai.ts packages/server-utils/src/integrations/tracing-channel/anthropic.ts packages/server-utils/src/integrations/tracing-channel/google-genai.ts packages/server-utils/src/vercel-ai/vercel-ai-dc-subscriber.ts
32	XL	High	Middleware	middleware.<library> / hook.fastify / http.server.middleware	middleware	middleware exists	Collapse framework identity for middleware and request-pipeline hooks. Router layers are handled separately as router.	code.namespace or framework; middleware.type; middleware.name	packages/core/src/integrations/express/patch-layer.ts packages/server-utils/src/integrations/tracing-channel/express/instrumentation.ts packages/node/src/integrations/tracing/connect/vendored/instrumentation.ts packages/node/src/integrations/tracing/koa/vendored/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/koa.ts packages/node/src/integrations/tracing/hapi/vendored/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/hapi-utils.ts packages/node/src/integrations/tracing/fastify/v3/instrumentation.ts packages/server-utils/src/integrations/tracing-channel/fastify/instrumentation.ts packages/node/src/integrations/tracing/hono/index.ts packages/hono/src/shared/wrapMiddlewareSpan.ts packages/elysia/src/withElysia.ts packages/nestjs/src/integrations/helpers.ts packages/nuxt/src/runtime/hooks/wrapMiddlewareHandler.ts packages/nitro/src/runtime/hooks/captureTracingEvents.ts packages/tanstackstart-react/src/server/utils.ts packages/nextjs/src/common/wrapMiddlewareWithSentry.ts packages/nextjs/src/common/enhanceMiddlewareRootSpan.ts packages/nextjs/src/server/enhanceHandleRequestRootSpan.ts packages/nextjs/src/edge/index.ts
