  // The following fields define the set of enabled trace categories. Each list
  // item is a glob.
  //
  // To determine if category is enabled, it is checked against the filters in
  // the following order:
  //
  //   1. Exact matches in enabled categories.
  //   2. Exact matches in enabled tags.
  //   3. Exact matches in disabled categories.
  //   4. Exact matches in disabled tags.
  //   5. Pattern matches in enabled categories.
  //   6. Pattern matches in enabled tags.
  //   7. Pattern matches in disabled categories.
  //   8. Pattern matches in disabled tags.
  //
  // If none of the steps produced a match, the category is enabled by default.
  //
  // Examples:
  //
  //  - To enable all non-slow/debug categories:
  //
  //       No configuration needed, happens by default.
  //
  //  - To enable a specific category:
  //
  //       disabled_categories = ["*"]
  //       enabled_categories = ["my_category"]
  //
  //  - To enable only categories with a specific tag:
  //
  //       disabled_tags = ["*"]
  //       enabled_tags = ["my_tag"]
  //

  // Default: []

  // Default: []
  repeated string enabled_categories = 2;

  // Default: [“slow”, “debug”]
  repeated string disabled_tags = 3;

  // Default: []
