OpenTelemetry Collector Config

Editor support for OpenTelemetry Collector configuration files inside VS Code: syntax highlighting, completion, hover docs, diagnostics, cross-file references, and embedded OTTL support — powered by a bundled language server.

Features

• Diagnostics — unknown components, malformed pipelines, type mismatches checked against the collector JSON schemas.
• Completion + hover — component IDs, signal types, field names, with descriptions sourced from the collector schemas.
• Cross-file references — go-to-definition and find-references across multi-file config-set layouts.
• Embedded OTTL — range-restricted parsing inside statements, conditions and similar OTTL-bearing keys.
• Workspace heuristics — automatic grouping of otelcol-config*.yaml files into a single logical config set.

Activation

The extension claims:

• Files matching otelcol*.yaml / otelcol*.yml / otelcol-configset.yaml.
• Any YAML file whose first line is # otelcol-configset:, # otelcol, or # opentelemetry-collector.

For other naming schemes, set the file's language manually via Change Language Mode → OpenTelemetry Collector.

Settings

See the full list in Settings → Extensions → OpenTelemetry Collector Config.

Other editors

The same language server backs Zed, Helix and JetBrains via the opentelemetry-collector-config npm package. See the per-editor docs in the GitHub repository.
