End an OpenTelemetry span

Spans created with start_local_active_span() end automatically by default. You must end every other span manually, by calling end_span, or using the end_on_exit argument of local_active_span() or with_active_span().

Usage

end_span(span)

Arguments

span

The span to end.

Value

Nothing.

Examples

fun <- function() {
  # start span, do not activate
  spn <- otel::start_span("myfun")
  # do not leak resources
  on.exit(otel::end_span(spn), add = TRUE)
  myfun <- function() {
     # activate span for this function
     otel::local_active_span(spn)
     # create child span
     spn2 <- otel::start_local_active_span("myfun/2")
  }

  myfun2 <- function() {
    # activate span for this function
    otel::local_active_span(spn)
    # create child span
    spn3 <- otel::start_local_active_span("myfun/3")
  }
  myfun()
  myfun2()
  end_span(spn)
}
fun()
