Context

Part of Configuration Inversion (Step 1) - Stack progress:

  1. → #7548 - Add GitLab step and JSON configuration file (this PR)
  2. #7688 - Reorganize keys, split config keys and platform keys
  3. #7698 - Generate ConfigurationKeys with source generator
  4. #7689 - Aliases handling and analyzers
  5. #7697 - Replace manual ConfigurationKeys by generated ones in the whole solution

Summary

Adds centralized configuration registry (supported-configurations.json + supported-configurations-docs.yaml) containing ~280 configuration keys with automated GitLab CI validation.

Changes

Configuration Files:

  • supported-configurations.json - Machine-readable registry of all configuration keys with versions, aliases, and deprecations
  • supported-configurations-docs.yaml - Human-readable documentation for each configuration key

CI/CD:

  • Added validate_supported_configurations_local_file step to .gitlab-ci.yml
  • Updated .gitlab/one-pipeline.locked.yaml to reference validation template

File Structure:

{
  "supportedConfigurations": { "DD_TRACE_ENABLED": { "version": ["A"] }, ... },
  "aliases": { "DD_AGENT_HOST": ["DD_TRACE_AGENT_HOSTNAME", ...], ... },
  "deprecations": { "DD_TRACE_ANALYTICS_ENABLED": "Deprecated - ...", ... }
}

Motivation

Provides single source of truth for configuration keys to enable:

  • Automated documentation validation
  • Cross-tracer compatibility checks
  • Configuration migration tooling
  • Automated doc generation

See: Configuration Registry Design Doc

Validation

GitLab CI validates JSON structure, naming conventions, and schema compliance on every build.

Commit Details

2639cf0 - Initial Configuration Registry

  • Added supported-configurations.json with ~280 configuration keys organized by version (A/B/C)
  • Includes aliases section mapping primary keys to deprecated/alternative names
  • Includes deprecations section with deprecation messages
  • Added GitLab CI validation step to ensure file integrity
  • Updated one-pipeline lock file to reference validation template

70e632e - Configuration Documentation

  • Added supported-configurations-docs.yaml with detailed XML documentation for each configuration key
  • Provides human-readable descriptions, default values, and usage examples
  • Includes <seealso> references to relevant code classes
  • Complements the machine-readable JSON with developer-friendly documentation
  • Enables automated generation of configuration documentation from a single source

Execution-Time Benchmarks Report ⏱️

Execution-time results for samples comparing the following branches/commits:

Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:

  • Welch test with statistical test for significance of 5%
  • Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

Where do our other tracing libraries have their declared configurations files? It seems a little strange to me to have a content file like this inside a subfolder alongside existing code.

I thought perhaps adding it to the Configuration folder made sense? but I don't mind changing it if you think it should be somewhere else, at the root in the Solution Items?
in dd-trace-js it's in packages/dd-trace/src/supported-configurations.json
in java, it's in a metadata folder
in ruby it's at the root..

Since this would be difficult to validate 100%, here's what I did to quickly validate this and feel confident about the contents:

  • I selected a sample of 5-10 configuration keys here and compared by eye the description with the contents in the existing configuration keys XML.
  • I did a CTRL+F in my local tracer/src/Datadog.Trace/Configuration folder for const string and removed non-applicable variables (non-DD/non-OTEL configs) results from my search. That left 256 entries, and I compared that count to CTRL+F : | in this doc, which had 253 results, so that's close enough for my brute force method.

Can we update the product name later? Or does this need to be decided right now and be set in stone? The reason I ask is because I think the various DD_LOGS_DIRECT_SUBMISSION_* flags and DD_LOGS_OTEL_ENABLED could all be categorized as a "Logs" product, but I would rather have that as a separate conversation and not block your work

Yes, the product is something I added for the dotnet tracer to reflect already existing inner classes but it's not set in stone. But that's a good point, how to refactor autogenerated elements? From experience, you can ctrl+R,R on the inner class in the ConfigurationKeys.g.cs which will refactor everywhere in the solution, then change find and replace product name in the supported-configurations.json, so that the newly generated file is the same as what you just refactored. Not sure this is clear lol, I think I'll add something in the docs about this

Overall LGTM. There's a lot of configurations so I listed my review process in my comments 😅

P1 Badge Remove ambiguous aliases that reuse canonical keys

The alias table introduces names that are already defined as primary configuration keys and even maps the same alias to multiple entries. For instance, DD_TRACE_PROPAGATION_STYLE is declared as a standalone key earlier in the file but here it is also listed as an alias for both DD_TRACE_PROPAGATION_STYLE_EXTRACT and DD_TRACE_PROPAGATION_STYLE_INJECT; likewise OTEL_EXPORTER_OTLP_PROTOCOL is reused for the metrics and logs variants. Downstream tooling that resolves aliases cannot deterministically choose which canonical key to use, so one of the entries will be dropped or the wrong configuration documented. Each alias should point to exactly one canonical key, and alias names should not also appear as canonical keys.

I'm gonna 👍🏽 because it does bring up an interesting point about

DD_TRACE_PROPAGATION_STYLE
DD_TRACE_PROPAGATION_STYLE_EXTRACT
DD_TRACE_PROPAGATION_STYLE_INJECT

DD_TRACE_PROPAGATION_STYLE really is just a fallback (alias) for the other two.

I could remove DD_TRACE_PROPAGATION_STYLE
I still need OTEL_EXPORTER_OTLP_PROTOCOL that is directly used in TracerSettings

The thing is if they're not listed as keys above, they wont generate a constant in ConfigurationKeys later on, and if it's needed directly without fallbacks by the ConfigurationBuilder like it is for OtlpGeneralProtocol then there needs to be a ConfigurationKeys constant

Looks like this small grammatic error was copy/pasted many times 😅

… keys (#7688)

## Context

Part of **Configuration Inversion (Step 2)** - Stack progress:
1. [#7548](#7548) - Add
GitLab step and JSON configuration file
2. **→ [#7688](#7688) -
[Config registry] Reorganize keys, split config keys and platform
keys(this PR)**
3. [#7698](#7698) -
Generate ConfigurationKeys with source generator
4. [#7689](#7689) -
Aliases handling and analyzers
5. [#7697](#7697) -
Replace manual ConfigurationKeys by generated ones in the whole solution
## Summary

Separates platform-specific environment variables into `PlatformKeys`
class and adds Roslyn analyzers to enforce proper usage of configuration
keys throughout the codebase.

## Changes

**Platform Keys Separation:**
- Created `PlatformKeys` class for external platform environment
variables (AWS, Azure, GCP, Kubernetes, CLR Profiler), those that don't
start with DD_ and come from other platforms.
- Updated all references throughout codebase to use `PlatformKeys` for
platform-specific variables
- Keeps `ConfigurationKeys` focused only on Datadog configuration

**Roslyn Analyzers:**
- **DD0007**: Platform key analyzer - Enforces use of `PlatformKeys` for
external platform environment variables
- **DD0008**: ConfigurationBuilder analyzer - Enforces use of
`ConfigurationKeys` or `PlatformKeys` constants in
`ConfigurationBuilder.WithKeys()` calls
- Prevents hardcoded strings and ensures type safety

**Configuration Mapping:**
- Added `configuration_keys_mapping.json` to map environment variable
names to their `ConfigurationKeys` constant names, so that we avoid
renaming hundreds of variables according to automatically source
generated deducted ones.
- Enables preservation of original constant names during refactoring
- Supports source generator integration

**Code Updates:**
- Updated `TracerSettings`, test files, and profiler code to use
`PlatformKeys`
- Replaced manual `ConfigurationKeys` with generated version from
`supported-configurations.json`
- Added missing `DD_TRACE_LOG_PATH` to configuration registry

## Motivation

Ensures clean separation between Datadog and platform configuration by:
- Preventing accidental mixing of platform and Datadog keys
- Enforcing compile-time validation of configuration key usage
- Making it clear which keys are owned by Datadog vs external platforms
- Catching configuration errors at build time instead of runtime

## Validation

- Roslyn analyzers run on every build
- All existing tests pass with updated key references
- Analyzers report clear diagnostic messages for violations

## Related Work

This PR builds on the configuration registry foundation established in
#7548:
- **Commit `2639cf0`** added `supported-configurations.json` with ~280
keys, aliases, deprecations, and GitLab CI validation
- **Commit `70e632e`** added
[supported-configurations-docs.yaml](cci:7://file:///Users/anna.yafi/go/src/github.com/DataDog/dd-trace-dotnet3/tracer/src/Datadog.Trace/Configuration/supported-configurations-docs.yaml:0:0-0:0)
