General Information
Extensions provide capabilities on top of the primary functionality of the collector. Generally, extensions are used for implementing components that can be added to the Collector, but which do not require direct access to telemetry data and are not part of the pipelines (like receivers, processors or exporters). Example extensions are: Health Check extension that responds to health check requests or PProf extension that allows fetching Collector's performance profile.
Supported service extensions (sorted alphabetically):
The contributors repository may have more extensions that can be added to custom builds of the Collector.
Ordering Extensions
The order extensions are specified for the service is important as this is the
order in which each extension will be started and the reverse order in which they
will be shutdown. The ordering is determined in the extensions tag under the
service tag in the configuration file, example:
service:
# Extensions specified below are going to be loaded by the service in the
# order given below, and shutdown on reverse order.
extensions: [extension1, extension2]

Types ¶
type CreateFunc ¶
CreateFunc is the equivalent of Factory.Create(...) function.
type Extension ¶
Extension is the interface for objects hosted by the OpenTelemetry Collector that don't participate directly on data pipelines but provide some functionality to the service, examples: health check endpoint, z-pages, etc.
type Factory ¶
type Factory interface {
component.Factory
// Create an extension based on the given config.
Create(ctx context.Context, set Settings, cfg component.Config) (Extension, error)
// Stability gets the stability level of the Extension.
Stability() component.StabilityLevel
// contains filtered or unexported methods
}
func NewFactory ¶
func NewFactory( cfgType component.Type, createDefaultConfig component.CreateDefaultConfigFunc, createServiceExtension CreateFunc, sl component.StabilityLevel, ) Factory
NewFactory returns a new Factory based on this configuration.
type Settings ¶ added in v0.103.0
type Settings struct {
// ID returns the ID of the component that will be created.
ID component.ID
component.TelemetrySettings
// BuildInfo can be used by components for informational purposes
BuildInfo component.BuildInfo
}
Settings is passed to Factory.Create(...) function.
