fix(warehouse): read the current semconv key wherever we only read the legacy one - #1190
Conversation
…e legacy one An audit of every attribute key in the repo against the semconv v1.44.0 registry found read paths pinned to the deprecated spelling. Spans from current OTel instrumentation landed in an empty bucket or matched nothing: - traces: the `http_method` group-by (timeseries and breakdown) read only `http.method`, and the raw `environment` breakdown read only `deployment.environment`. Both now coalesce through `semconv-renames` (new `httpRequestMethodExpr`, existing `deploymentEnvExpr`). - span filters: the alias table now also covers `db.system`, `messaging.destination`, `rpc.system` and `http.host` -> `server.address`, so the service-map drilldowns and the gRPC template match either key. - where-clause: `deployment.environment.name` normalizes to the environment dimension instead of falling through to a span-attribute filter. - service dependencies drilldowns: the parser drops `(a OR b)` groups, so the HTTP drill never filtered on its target and the RPC drill would not either. Each drill is now a single aliased key; an RPC target that came from the system filters on `rpc.system.name`. - trace page and peek sheet: environment badge and 5xx detection read the current keys first. - setup audit, error prompt and log chips know `service.peer.name`, `rpc.system.name`, `rpc.response.status_code`, `url.full` and the current HTTP and messaging keys. The service-map external-edge rollup still classifies RPC off `rpc.system` and `rpc.service`; fixing that needs a migration and ships separately.
Maple review🔴 Confidence 2/5 · risky as written Read paths now accept the current semconv spelling next to the legacy one: group-bys, span filter aliases, the where-clause environment key, the trace page badges and the audit key lists. Safe to merge, but two dependency drilldowns still cannot match the targets the rollup builds.

…ority The service map names a messaging edge by its system when the span has no destination, and an http edge from server.address, then http.host, then url.authority. The drills only handled the first spelling of each, so those rows opened an empty trace list. Messaging edges named by the system now drill on messaging.system, and the server.address alias covers url.authority in the rollup's order. The drill builder moves to dependency-drill.ts with tests, including one that every drill parses without a dropped clause.

…s use httpRequestMethodExpr preferred http.request.method, while the span filter aliases and trace_list_mv's HttpMethod prefer http.method. On a span that carries both keys with different values, a group-by bucket and the filter it drills into disagreed. The group-by now compiles to the MV's expression.
Maple review🟢 Confidence 4/5 · likely safe to merge Reads the current semconv spelling alongside the deprecated one in trace filters, group-bys and the service-dependency drills, and rewrites each drill as one aliased key. The changed files are internally consistent and safe to merge.

Every drill on the service Dependencies tab opened an empty or unfiltered trace list, and has since the tab shipped: - `SpanKind = 'Client'` is not a where-clause field. The traces page treats unknown keys as span attributes, so it filtered on an attribute named `SpanKind` that no span carries. - The traces page filters root spans unless `root_only = false`, and a client span is almost never a root. - `ILIKE` is not a supported operator, so the service drill's target clause was dropped. Drills now open the span-level list and filter on one aliased target key. Edges named after their messaging or rpc system also require the missing destination or rpc.service, so they no longer match every destination of the system, and the rpc system drill uses the legacy key the rollup reads. Also from review: - A span filter reads the spelling the user typed first, so a saved filter on a legacy key keeps matching spans that dual-emit a different value under the new key. HTTP method and status stay legacy-first to agree with trace_list_mv. - rootHttpMethod and rootHttpStatusCode read both spellings. - A numeric gRPC status of 0 under rpc.response.status_code is not an error.
Maple review🟢 Confidence 4/5 · likely safe to merge Widens the read paths that only understood a deprecated semconv spelling — trace group-bys and filters, the where-clause key normalizer, dependency drilldowns, the gRPC template, the setup audit and the UI chips — so a span carrying either spelling is grouped, filtered and drilled consistently. Safe to merge.

- Around line 34-35: Update the dependency-drill filtering around namedBySystem
so fallback behavior is determined by the rollup’s actual fallback status, not
inferred from target/system equality; apply the same fix to the RPC branch.
Ensure filters still include spans with a present destination or service
matching the system name, and add regression cases for both matching-name
scenarios.

treating every status except `"0"` and `"OK"` as an error. Keep unrecognized
status values neutral.

Every non-OK value was an error chip. Semconv treats only UNKNOWN, DEADLINE_EXCEEDED, UNIMPLEMENTED, INTERNAL, UNAVAILABLE and DATA_LOSS as errors on a gRPC server span; the chip does not know the span kind, so other gRPC codes are a warning and values from other rpc systems stay neutral. Also documents and pins the one drill gap left: a destination or rpc.service named after its system shares an edge with the fallback spans, and the drill reaches only the fallback half because the where-clause has no OR.

A gRPC-looking value from another rpc system ("2", "INTERNAL") still turned
red. pickImportantAttributes now passes the row's rpc.system.name (or legacy
rpc.system) to getChipTone, and the gRPC classification applies only when that
says grpc; otherwise the status stays neutral.

Why
I audited every attribute key in the repo against the semconv v1.44.0 registry. A few read paths only understand the deprecated spelling, so spans from current OTel instrumentation either land in an empty group or match no filter. Our own SDKs write both spellings, which is why we never saw this on our own telemetry.
What changes
http_methodgroup-by read onlyhttp.method, and the rawenvironmentbreakdown read onlydeployment.environment. Both now accept either spelling, preferring the current one (httpRequestMethodExpr,deploymentEnvExpr).db.system↔db.system.name,messaging.destination↔.name,rpc.system↔rpc.system.nameandhttp.host→server.address. The gRPC dashboard template now filters onrpc.system.name.deployment.environment.nameis treated as the environment filter. Before, it fell through to a span-attribute filter, which never matches because it is a resource attribute.SpanKind = 'Client'isn't a where-clause field, so the traces page filtered on a span attribute namedSpanKindthat no span has. The page also filters root spans only unlessroot_only = false, and a client span is almost never a root. On top of that, the parser drops(a OR b)groups and doesn't supportILIKE. Drills now open the span-level list and filter on one target key that matches both spellings. Edges named after their messaging or RPC system also require the destination orrpc.serviceto be absent, so they don't match every destination of that system. The builder lives independency-drill.ts, and its tests run the clause through the traces page's own parser.trace_list_mv.service.peer.name,rpc.system.name,rpc.response.status_code,url.fulland the current HTTP and messaging keys.Not in this PR
The service-map external-edge rollup still decides whether a span is RPC from
rpc.system/rpc.servicealone. Fixing it changes a materialized view, which needs a ClickHouse migration, a local schema bump and a Tinybird deploy, so it will ship separately.Testing
ch.test.tscases: thehttp_methodgroup-by (breakdown and timeseries) and the environment breakdown now read both spellings, and a filter on either spelling matches both keys for each new alias pair.where-clause.test.tscovers the new environment key alias.src/lib. Typecheck passes for domain, query-engine and web.Need help on this PR? Tag
