# OTel naming-consistency check
`check_otel_naming.py` enforces the OpenTelemetry span-attribute naming
convention documented in
[CONTRIBUTING.md](../../../CONTRIBUTING.md#telemetry-span-attribute-naming)
across every layer of the telemetry pipeline. The `*SpanNames.h` constants are
the single source of truth (L1); every other layer must agree with them.
## Running locally
```
python .github/scripts/otel-naming/check_otel_naming.py
```
It takes no arguments, can be run from any directory inside the repo, and uses
only the Python standard library (no `pip install`, matching the levelization
check). A non-zero exit code means a violation was found; the output lists each
violation as `RULE | location | token | expected`.
## What it checks
The valid key set is **derived dynamically from the OTel code** — there is no
hardcoded allowlist:
- **L1 keys** come from the `namespace attr { ... }` blocks of every
`*SpanNames.h`, resolving the `makeStr("x")` / `join(seg::a, seg::b)` DSL
(cross-file, so `join(seg::rpc, ...)` resolves `seg::rpc` from the base
`SpanNames.h`).
- **Legitimate dotted keys** = the resource attrs declared in the base
`SpanNames.h` (`xrpl.network.*`) plus the `semconv::service::*` keys the code
passes to `Resource::Create()` in `Telemetry.cpp` (`service.*`). A dotted key
declared in any other header is a violation.
### Rules (each fails the build, when its inputs are present)
| Rule | Check |
| ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| A | No stray dotted span-attribute key (only the derived resource keys may be dotted). |
| G | Attribute keys are `lower_snake_case` (`^[a-z][a-z0-9_]*$` per dot-segment) — no camelCase, UPPERCASE, or spaces. |
| F | No string literals as attribute keys or span-name arguments in `setAttribute`/`addEvent`/`span`/`childSpan`. Attribute _values_ are exempt (runtime data); `*SpanNames.h` definitions and test files are exempt. |
| B | Every collector `spanmetrics.dimensions` name exists in the L1 key set. |
| C | Every Tempo span-filter tag exists in the L1 key set. |
| D | Every dashboard PromQL label (non-builtin) exists in the L1 key set. |
| E | Every runbook attribute reference exists in the L1 key set. |
Rule F runs **unconditionally** (it is a purely syntactic check on the
call-sites and needs no `*SpanNames.h`), so a code path that calls
`SpanGuard::span`/`setAttribute` directly without ever defining a header is
still caught.
### Warnings (printed, never fail the build)
| Rule | Check |
| ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| H | A namespace-qualified constant (e.g. `foo::bar::myKey`) used at a telemetry call-site is not defined in any `*SpanNames.h`. The constant should live in the proper header; defining it in-place bypasses rules A/G/F. Warns rather than fails — the argument may be a legitimately dynamic value, and the header may live on a later branch. Bare locals and `std::` names are not warned. |
## Presence-gated
Every rule runs **only when the source files it needs are present** in the tree
and is otherwise skipped (printed as `SKIP: <rule> — <reason>`), never failed.
This keeps the check correct no matter how telemetry work is split across PRs —
a stacked chain, one large PR, or independent per-stage PRs where (for example)
the collector config lands before the dashboards. The collector/Tempo/dashboard/
runbook layers are introduced in later phases; on a branch without them, only
the L1-intrinsic rules (A, F) run.

"""
Usage: check_naming.py
This script takes no parameters and can be called from any directory inside the
repository (it locates the repo root via `git rev-parse`).
Enforces the OpenTelemetry span-attribute naming convention documented in
CONTRIBUTING.md ("Telemetry span attribute naming") across every layer of the
telemetry pipeline. The `*SpanNames.h` constants are the single source of truth
(L1); every other layer must agree with them.
Design principles
-----------------
1. No hardcoded allowlist. The set of valid attribute keys — including which
dotted keys are legitimate resource attributes — is derived dynamically by
parsing the repository's own OTel code:
* `*SpanNames.h` `namespace attr { ... }` blocks (the underscore/bare keys
and the `join(seg::..., ...)` dotted resource compositions), and
* the keys the code passes to `Resource::Create({ ... })` in Telemetry.cpp
(the standard `semconv::service::*` keys -> service.name/version/...).
2. Presence-gated enforcement. Every rule runs ONLY when the source files it
needs are present in the tree, and is otherwise skipped (never failed). This
keeps the check correct no matter how work is split across PRs: a stacked
chain, one large PR, or independent per-stage PRs where (for example) the
collector config lands in a different PR than the dashboards. The check never
assumes a file from another phase/PR exists.
Layers
------
L1 code : src/**/*SpanNames.h, include/**/*SpanNames.h (ground truth)
L1 resource : src/libxrpl/telemetry/Telemetry.cpp (dotted allowlist)
L1 callsites : setAttribute/addEvent/span/childSpan in src/**, include/**
L2 collector : docker/telemetry/otel-collector-config.yaml (spanmetrics dims)
L3 tempo : docker/telemetry/tempo.yaml (span filter tags)
L4 dashboards: docker/telemetry/grafana/dashboards/*.json (PromQL labels)
L5 runbook : docs/telemetry-runbook.md (attr tables)
Rules (each FAILS the build, when its inputs are present)
---------------------------------------------------------
A No stray dotted span-attribute key. A dotted `<a>.<b>` used as a span
attribute that is not in the derived resource-key set is a violation.
G Attribute keys must be lower_snake_case (^[a-z][a-z0-9_]*$ per segment).
Flags camelCase, UPPERCASE, spaces, and other stray characters.
F No string literals as attribute keys or span-name arguments. The
setAttribute/addEvent key and the span/childSpan prefix/name args must
reference a *SpanNames.h constant, never a "literal". Attribute VALUES are
exempt (runtime data). Definitions inside *SpanNames.h are exempt, and
test files are exempt (they pass arbitrary literals to exercise the API).
B Every collector spanmetrics dimension exists in the L1 key set.
C Every tempo span-filter tag exists in the L1 key set.
D Every dashboard PromQL label (non-builtin) exists in the L1 key set.
E Every attribute named in the runbook tables exists in the L1 key set.
Warnings (printed, but do NOT fail the build)
----------------------------------------------
H A constant referenced at a telemetry call-site is not defined in any
*SpanNames.h. Span constants should live in the corresponding
*SpanNames.h (single source of truth); defining one in-place bypasses the
naming rules. A warning (not a failure) because the argument may instead
be a legitimately dynamic local (e.g. a computed span-name leaf).
Exit code is non-zero if any present-and-enforced rule finds a violation.
Warnings never change the exit code.
