OpenTelemetry Collector upgrade — check your config before upgrading

Flags removed Collector components and legacy semantic-convention attribute names in OpenTelemetry Collector YAML before the upgrade drops your pipeline. Runs entirely in your browser — nothing is uploaded.

as of

Free here: Lint the Collector config you have open and see every removed component and legacy attribute name in it, with the replacement spelled out.. In the editor: Scan every YAML in the repo at once, export the findings as JSON or Markdown, and fail a CI job on blockers. — that part asks for a licence key.

Same engine as the VS Code extension, byte for byte.
