OTLP exporter 🔗

The OTLP exporter sends metrics, traces, and logs through gRPC using the OTLP format. See Process your data with pipelines for more information. The supported pipeline types are traces, metrics, and logs. By default, this exporter requires TLS and provides queued retry capabilities.

Note

For information on the OTLP/HTTP exporter, see OTLP/HTTP exporter.

Get started 🔗

The OTLP exporter is included in the Splunk Distribution of OpenTelemetry Collector default configuration in host monitoring (agent) mode for all data pipelines: metrics, traces, and logs. Learn more in Collector default configuration and Collector deployment modes.

The following settings are required:

endpoint. Address to which the exporter is going to send OTLP data, using the gRPC protocol.
- No default value.
- gRPC supports DNS as the default name-system. To learn more about the valid name syntax, see gRCP Name Resolution in GitHub.
- If you’re using a scheme of https, then client transport security is enabled and overrides the insecure setting.
tls. See TLS Configuration Settings in this document for the full set of available options.
- By default, tls: insecure is set to true.
- Mutual TLS (mTLS) is also supported. See more at TLS/mTLS configuration in GitHub.
