Overview ¶

Functions ¶
func Do ¶
Do sends r. Errors that retrying can fix (connection errors, 408, 429 and 5xx) are returned as they are, or with batch.RetryAfter; the rest are batch.Permanent.
func Endpoint ¶
Endpoint is where an OTLP signal ("logs", "traces") is posted: explicit, or OTEL_EXPORTER_OTLP_<SIGNAL>_ENDPOINT, or OTEL_EXPORTER_OTLP_ENDPOINT with /v1/<signal> added, or a collector on localhost.
func ParseHeaders ¶
ParseHeaders reads ParsePairs' format as headers.
