chore: remove legacy metrics in connectors by roroghost17 · Pull Request #6403 · maximhq/bifrost

roroghost17 · 2026-08-21T08:30:26Z

Summary

This PR removes all legacy/deprecated telemetry attribute constants and their emission sites, completing the migration from gen_ai.*-namespaced Bifrost-internal attributes to the canonical bifrost.* namespace. It also removes the deprecated x-bf-prom-* header prefix support from the Prometheus plugin and HTTP transport.

Changes

Removed all gen_ai.*-namespaced constants that were duplicating Bifrost-internal concepts (AttrVirtualKeyID, AttrTeamID, AttrCustomerID, AttrSelectedKeyID, AttrFallbackIndex, AttrNumberOfRetries, AttrRequestID, AttrErrorType, etc.) and their emission call sites across bifrost.go, llmspan.go, and converter.go
Removed deprecated token usage attribute constants AttrPromptTokens and AttrCompletionTokens (replaced by AttrInputTokens / AttrOutputTokens) and all emission sites
Removed AttrLegacyRetryCount (retry.count) constant and replaced its usage with AttrBifrostRetries
Removed AttrTimeToFirstToken (nanosecond TTFT) and its emission; the OTel plugin now reads AttrTimeToFirstChunk (seconds) directly, eliminating the /1e9 conversion at read time
Removed AttrDimensions, AttrEncodingFormat, AttrN, AttrPromptTokenDetailsCachedRead, AttrPromptTokenDetailsCachedWrite legacy constants and their emission sites
Updated buildSpanAttrs and entitySetFromAttrs call sites in the OTel plugin to read from bifrost.* keys instead of the removed gen_ai.* keys
Removed x-bf-prom-* header processing from collectPrometheusKeyValues, applyCustomLabels, and the HTTP transport context builder; the prefix is now silently swallowed to prevent forwarding but no longer consumed as a dimension source

Type of change

Affected areas

How to test

go test ./...

Verify that spans and metrics emitted after this change carry only bifrost.*-namespaced attributes for routing/governance fields, and that gen_ai.usage.input_tokens / gen_ai.usage.output_tokens are present while gen_ai.usage.prompt_tokens / gen_ai.usage.completion_tokens are absent. Confirm that sending x-bf-prom-* headers no longer populates any Prometheus label or dimension.

Breaking changes

Yes
No

Any dashboards, alerts, or downstream consumers still reading the removed gen_ai.* attribute names (gen_ai.virtual_key_id, gen_ai.team_id, gen_ai.number_of_retries, gen_ai.usage.prompt_tokens, gen_ai.usage.completion_tokens, gen_ai.response.time_to_first_token, etc.) will stop receiving data. Migrate queries to the corresponding bifrost.* keys or the updated gen_ai.* spec keys (gen_ai.usage.input_tokens, gen_ai.usage.output_tokens, gen_ai.response.time_to_first_chunk). The x-bf-prom-* request header prefix is fully removed; use x-bf-dim-* instead.

📝 Walkthrough

Summary by CodeRabbit

Bug Fixes
- Standardized tracing and metrics on current attribute names for retries, tokens, routing, errors, embeddings, and streaming latency.
- Removed legacy telemetry aliases and custom-label headers.
- Improved request ID, fallback, context, and custom-label consistency in observability data.
- Added support for decoding chained response encodings, including gzip, deflate, Brotli, and zstd.
- Improved detection of sensitive authentication headers.
Documentation
- Clarified that removed legacy headers are ignored and not forwarded upstream.

Walkthrough

The change removes legacy tracing attributes and telemetry header fallbacks. Provider utilities now filter passthrough encodings and decode chained response encodings. OpenTelemetry and telemetry components use canonical Bifrost keys and dimensions.

Changes

Canonical observability and provider encoding

Layer / File(s)	Summary
Canonical trace contracts and producers `core/schemas/trace.go`, `core/bifrost.go`, `core/providers/utils/utils.go`, `framework/tracing/llmspan.go`	Trace schemas and span population retain canonical attributes and remove legacy aliases for governance, usage, errors, retries, fallback indexes, embeddings, and timing.
Provider encoding passthrough and decoding `core/providers/utils/utils.go`	Passthrough headers now use buffered and streaming encoding allowlists. Response decoding supports chained gzip, deflate, Brotli, and zstd encodings.
OpenTelemetry attribute consumption `plugins/otel/converter.go`, `plugins/otel/main.go`, `plugins/otel/entityset_test.go`	OpenTelemetry conversion and metrics use canonical Bifrost request, governance, retry, token, timing, and team attributes.
Canonical telemetry dimensions `plugins/telemetry/main.go`, `plugins/telemetry/utils.go`, `plugins/telemetry/main_test.go`, `transports/bifrost-http/lib/ctx.go`	Custom labels use canonical context dimensions and `x-bf-dim-` headers. Tests cover dimension precedence and missing labels. Removed `x-bf-prom-` headers are swallowed and excluded from forwarding.

Check BilledUsage first and fall back to the response, so a failed turn is priced from what the provider actually billed. The token attributes already had the right precedence, since Tracer merges error attributes after response attributes; a test now pins that ordering. Affected packages: - framework/tracing/tracer.go - framework/tracing/llmspan_test.go Co-Authored-By: Claude <noreply@anthropic.com> * [fix]: framework/tracing - emit the spec cached-read key on failed spans too The error path emitted only the legacy nested cached-read keys and missed gen_ai.usage.cache_read.input_tokens, which both success paths emit. Add the spec key alongside the legacy ones so failed and successful spans share one attribute contract. Affected packages: - framework/tracing/llmspan.go - framework/tracing/llmspan_test.go Co-Authored-By: Claude <noreply@anthropic.com> * fix(tracing): emit cache-write usage on failed spans * fix(tracing): address review - drop retired attrs, gate totals, split cache namespaces, guard cost - Remove AttrPromptTokens/AttrCompletionTokens/AttrPromptTokenDetailsCached* from the error path; maximhq#6403 deleted them from core. - Gate token totals on > 0 so a details-only BilledUsage does not stamp explicit zeros on the span. - Emit one cache namespace per request type (input_token_details.* for Responses, prompt_token_details.* otherwise), matching the success paths. - Only write gen_ai.usage.cost when > 0, falling back to the provider-reported BilledUsage.Cost when the catalog cannot price the model. Co-Authored-By: Claude <noreply@anthropic.com> * fix(tracing): drop zero response aggregates when the error carries BilledUsage A cancelled stream's accumulated response has usage with zero totals (the final usage chunk never arrived). Those zeros were stamped on the span before the gated error path merged, so a details-only BilledUsage left a false zero in gen_ai.usage.*. Skip them at the merge site; success spans and unbilled failures are unchanged.

## Summary This PR removes all legacy/deprecated telemetry attribute constants and their emission sites, completing the migration from `gen_ai.*`-namespaced Bifrost-internal attributes to the canonical `bifrost.*` namespace. It also removes the deprecated `x-bf-prom-*` header prefix support from the Prometheus plugin and HTTP transport. ## Changes - Removed all `gen_ai.*`-namespaced constants that were duplicating Bifrost-internal concepts (`AttrVirtualKeyID`, `AttrTeamID`, `AttrCustomerID`, `AttrSelectedKeyID`, `AttrFallbackIndex`, `AttrNumberOfRetries`, `AttrRequestID`, `AttrErrorType`, etc.) and their emission call sites across `bifrost.go`, `llmspan.go`, and `converter.go` - Removed deprecated token usage attribute constants `AttrPromptTokens` and `AttrCompletionTokens` (replaced by `AttrInputTokens` / `AttrOutputTokens`) and all emission sites - Removed `AttrLegacyRetryCount` (`retry.count`) constant and replaced its usage with `AttrBifrostRetries` - Removed `AttrTimeToFirstToken` (nanosecond TTFT) and its emission; the OTel plugin now reads `AttrTimeToFirstChunk` (seconds) directly, eliminating the `/1e9` conversion at read time - Removed `AttrDimensions`, `AttrEncodingFormat`, `AttrN`, `AttrPromptTokenDetailsCachedRead`, `AttrPromptTokenDetailsCachedWrite` legacy constants and their emission sites - Updated `buildSpanAttrs` and `entitySetFromAttrs` call sites in the OTel plugin to read from `bifrost.*` keys instead of the removed `gen_ai.*` keys - Removed `x-bf-prom-*` header processing from `collectPrometheusKeyValues`, `applyCustomLabels`, and the HTTP transport context builder; the prefix is now silently swallowed to prevent forwarding but no longer consumed as a dimension source ## Type of change - [ ] Bug fix - [ ] Feature - [x] Refactor - [ ] Documentation - [ ] Chore/CI ## Affected areas - [x] Core (Go) - [x] Transports (HTTP) - [ ] Providers/Integrations - [x] Plugins - [ ] UI (React) - [ ] Docs ## How to test ```sh go test ./... ``` Verify that spans and metrics emitted after this change carry only `bifrost.*`-namespaced attributes for routing/governance fields, and that `gen_ai.usage.input_tokens` / `gen_ai.usage.output_tokens` are present while `gen_ai.usage.prompt_tokens` / `gen_ai.usage.completion_tokens` are absent. Confirm that sending `x-bf-prom-*` headers no longer populates any Prometheus label or dimension. ## Breaking changes - [x] Yes - [ ] No Any dashboards, alerts, or downstream consumers still reading the removed `gen_ai.*` attribute names (`gen_ai.virtual_key_id`, `gen_ai.team_id`, `gen_ai.number_of_retries`, `gen_ai.usage.prompt_tokens`, `gen_ai.usage.completion_tokens`, `gen_ai.response.time_to_first_token`, etc.) will stop receiving data. Migrate queries to the corresponding `bifrost.*` keys or the updated `gen_ai.*` spec keys (`gen_ai.usage.input_tokens`, `gen_ai.usage.output_tokens`, `gen_ai.response.time_to_first_chunk`). The `x-bf-prom-*` request header prefix is fully removed; use `x-bf-dim-*` instead. ## Related issues ## Security considerations None. ## Checklist - [ ] I read `docs/contributing/README.md` and followed the guidelines - [ ] I added/updated tests where appropriate - [ ] I updated documentation where needed - [ ] I verified builds succeed (Go and UI) - [ ] I verified the CI pipeline passes locally if applicable
