OTLP JSON Exporter

Creates an exporter that converts traces to OpenTelemetry Protocol (OTLP) JSON format and sends them to an OTLP-compatible collector such as Jaeger, Grafana Tempo, or any OpenTelemetry Collector.

Usage

otlp_exporter(
  endpoint = Sys.getenv("OTEL_EXPORTER_OTLP_ENDPOINT", "http://localhost:4318"),
  headers = list(),
  service_name = Sys.getenv("OTEL_SERVICE_NAME", "r-agent"),
  batch_size = 100L,
  max_retries = 3L
)

Arguments

endpoint

OTLP HTTP endpoint URL. Defaults to the OTEL_EXPORTER_OTLP_ENDPOINT environment variable, or "http://localhost:4318" if unset.

headers

Named list of HTTP headers to include in requests (e.g., authentication tokens).

service_name

Service name reported in the resource attributes. Defaults to the OTEL_SERVICE_NAME environment variable, or "r-agent" if unset.

batch_size

Maximum number of traces to buffer before sending (default 100L). Traces are accumulated and sent when the buffer reaches this size. Use flush_otlp() to force-send buffered traces.

max_retries

Maximum number of retry attempts for transient HTTP errors (429, 5xx). Default 3L. Uses exponential backoff (1s, 2s, 4s).

Value

An S7 securetrace_exporter object.

Examples

if (FALSE) { # \dontrun{
# Export to a local Jaeger instance
exp <- otlp_exporter("http://localhost:4318")

tr <- Trace$new("my-run")
tr$start()
s <- Span$new("llm-call", type = "llm")
s$start()
s$set_model("gpt-4o")
s$set_tokens(input = 100L, output = 50L)
s$end()
tr$add_span(s)
tr$end()
export_trace(exp, tr)
flush_otlp(exp)
} # }
