  • All returned strings are capitalized.
  • "" is returned for integers that are out of Level enum range.

💡 Enhancements 💡

• component: component.Extension is temporarily set to be an alias of component.Component which will be reverted once it's moved to the extension package. Change your component.Host.GetExtensions() implementation to return map[ID]component.Component instead of map[ID]component.Extension (#6553)

  • go.opentelemetry.io/collector/component
• consumer: Split consumer into its own package (#6186) The import path for the consumer module can now be accessed directly:
  • go.opentelemetry.io/collector/consumer
