Exporter Helper

This is a helper exporter that other exporters can depend on. Today, it primarily offers queued retries and resource attributes to metric labels conversion.

⚠ This exporter should not be added to a service pipeline.

Configuration

The following configuration options can be modified:

  • retry_on_failure
    • enabled (default = true)
    • initial_interval (default = 5s): Time to wait after the first failure before retrying; ignored if enabled is false
    • max_interval (default = 30s): Is the upper bound on backoff; ignored if enabled is false
    • max_elapsed_time (default = 120s): Is the maximum amount of time spent trying to send a batch; ignored if enabled is false
  • sending_queue
    • enabled (default = true)
    • num_consumers (default = 10): Number of consumers that dequeue batches; ignored if enabled is false
    • queue_size (default = 5000): Maximum number of batches kept in memory before data; ignored if enabled is false; User should calculate this as num_seconds * requests_per_second where:
      • num_seconds is the number of seconds to buffer in case of a backend outage
      • requests_per_second is the average number of requests per seconds.
  • resource_to_telemetry_conversion
    • enabled (default = false): If enabled is true, all the resource attributes will be converted to metric labels by default.
  • timeout (default = 5s): Time to wait per individual attempt to send data to a backend.

The full list of settings exposed for this helper exporter are documented here.

type FactoryOption added in v0.7.0 

type FactoryOption func(o *factory)

FactoryOption apply changes to ExporterOptions.

func WithLogs added in v0.7.0 

func WithLogs(createLogsExporter CreateLogsExporter) FactoryOption

WithLogs overrides the default "error not supported" implementation for CreateLogsReceiver.

func WithMetrics added in v0.7.0 

func WithMetrics(createMetricsExporter CreateMetricsExporter) FactoryOption

WithMetrics overrides the default "error not supported" implementation for CreateMetricsReceiver.

func WithTraces added in v0.7.0

type Option added in v0.16.0 

type Option func(*baseSettings)

Option apply changes to baseSettings.

func WithCapabilities added in v0.27.0 

func WithCapabilities(capabilities consumer.Capabilities) Option

WithCapabilities overrides the default Capabilities() function for a Consumer. The default is non-mutable data. TODO: Verify if we can change the default to be mutable as we do for processors.

func WithQueue added in v0.7.0 

func WithQueue(queueSettings QueueSettings) Option

WithQueue overrides the default QueueSettings for an exporter. The default QueueSettings is to disable queueing.

func WithResourceToTelemetryConversion(resourceToTelemetrySettings ResourceToTelemetrySettings) Option

WithResourceToTelemetryConversion overrides the default ResourceToTelemetrySettings for an exporter. The default ResourceToTelemetrySettings is to disable resource attributes to metric labels conversion.

func WithRetry added in v0.7.0 

func WithRetry(retrySettings RetrySettings) Option

WithRetry overrides the default RetrySettings for an exporter. The default RetrySettings is to disable retries.

func WithShutdown 

func WithShutdown(shutdown componenthelper.ShutdownFunc) Option
