Glean Parser

This linter verifies that Glean telemetry configuration files (metrics.yaml and pings.yaml) are following the Glean schema and best practices by using the built-in linting functionality from glean_parser.

Common Issues

Empty Data Review

The most common error is having empty or placeholder values in the data_reviews field:

metrics:
  example:
    counter_metric:
      data_reviews:
        - ""      # This will cause an error
        - "TODO"  # This will also cause an error

The data_reviews field must contain a valid URL to a data review.
