| # FastForward OpenTelemetry | ||
|
|
||
| This module provies an output plugin for [OpenTelemetry metrics](https://github.com/open-telemetry/opentelemetry-proto/). It does not provide any tracing related functionality. | ||
|
|
||
| ## Configuration | ||
|
|
||
| * `endpoint` - The gRPC endpoint to send metrics to. | ||
| * `headers` - An optional map of headers to include in the [MetricService export](https://github.com/open-telemetry/opentelemetry-proto/blob/v0.7.0/opentelemetry/proto/collector/metrics/v1/metrics_service.proto#L32) RPC. | ||
|
|
||
| Here is an example configuration using the OpenTelemetry plugin: | ||
|
|
||
| ``` | ||
| output: | ||
| plugins: | ||
| - type: opentelemetry | ||
| endpoint: ingestion.example.com:443 | ||
| headers: | ||
| Authentication: Bearer Z29vZCBqb2IgZGVjb2RpbmcgdGhpcyBlYXN0ZXIgZWdn | ||
| ``` |
