By default, this exporter requires TLS and offers queued retry capabilities. ## Getting Started The following settings are required: - `endpoint` (no default): host:port to which the exporter is going to send OTLP trace data, using the gRPC protocol. The valid syntax is described [here](https://github.com/grpc/grpc/blob/master/doc/naming.md). If a scheme of `https` is used then client transport security is enabled and overrides the `insecure` setting. - `tls`: see [TLS Configuration Settings](../../config/configtls/README.md) for the full set of available options. - `retry_on_failure`: see [Retry on Failure](../exporterhelper/README.md#retry-on-failure) for the full set of available options. - `sending_queue`: see [Sending Queue](../exporterhelper/README.md#sending-queue) for the full set of available options. - `timeout` (default = 5s): Time to wait per individual attempt to send data to a backend. Example: ```yaml exporters: otlp_grpc: endpoint: otelcol2:4317 tls: cert_file: file.cert key_file: file.key otlp/2: endpoint: otelcol2:4317 tls: insecure: true ``` By default, `gzip` compression is enabled. See [compression comparison](../../config/configgrpc/README.md#compression-comparison) for details benchmark information. To disable, configure as follows: ```yaml exporters: otlp_grpc: ... compression: none ``` ## Advanced Configuration Several helper files are leveraged to provide additional capabilities automatically: - [gRPC settings](https://github.com/open-telemetry/opentelemetry-collector/blob/main/config/configgrpc/README.md) - [TLS and mTLS settings](https://github.com/open-telemetry/opentelemetry-collector/blob/main/config/configtls/README.md) - [Queuing, batching, retry and timeout settings](https://github.com/open-telemetry/opentelemetry-collector/blob/main/exporter/exporterhelper/README.md)
